  • Linux Mint is not losing it’s ground over Ubuntu distros

    Recently, there were lots of rumors floating around that Linux Mint is dominating over Ubuntu distros. The reports and graphs collected by “DistroWatch” stirred up the arguments even higher. 

    People supporting this phenomenon, referred to an even bigger increase in Linux Mint’s DistroWatch ranking, a chart derived from the number of hits each distro page on the site receives. 

    Like a domino effect of misinformation, this week has been chock full of reports by tech news sites that Ubuntu’s market share is declining, being surpassed by the Ubuntu spin-off and close cousin Linux-Mint.

    The source of this dramatic revelation is none other than DistroWatch, the site that all Ubuntu haters love to quote, and all Ubuntu lovers love to hate. – Joey sneddon, author OMG! Ubuntu

    To talk about the facts, we should notice what Distrowatch is claiming in their graphs and reports. The Data is collected from their own website and the user who visit their pages. Actually they store the information of the visitors who register a hit on their page (which cannot be taken as any official reports or something which can be a source for some conclusion).

    Putting aside the fact that Linux Mint’s recent increase in “Page hits” on the site has been helped in part by blog after blog talking about/linking to Mint on Distrowatch as evidence of its rise against Ubuntu. There is no doubt that Linux Mint is attracting renewed attention.

    But many in camp Mint/camp anti-Unity claim that the distro is now well on its way to being, if it’s not already, more popular than Ubuntu. One infamous ‘opensource’ site with a notable distaste for Ubuntu’s Unity desktop even assures its readers that:

    “There is no way that Ubuntu will cover this distance in the near future, unless they change something dramatically.”

    Well, if you are taking a website page hit as an evidence, why not talk about some other websites which can provide better information with Billions of hits per month? 

    Let’s say “Wikimedia”, can we get relevant information from that site? Well, we investigated a little bit and this is what we found.

    To help give perspective to the whole Mint Vs Ubuntu debate lets see what some real, hard stats say.

    The stats were posted on OMG! Ubuntu, which is quoted below:

    As ZDNet report, the Wikimedia Traffic Analysis Report of Operating Systems Visiting wikimedia Pages* in October 2011 show:

    * 16,924,000 hits from Ubuntu

    * 556,000 hits from Linux Mint


    Half a Billion computer using your OS is not a bad stat at all, but it does challenge the often aggressive posturing of many in the anti-Unity brigade that Unity has been nothing short of a disaster for Ubuntu.

     

    If we look fast-forward to look at Wikimedia stats fro December 2011 then things look even brighter for Ubuntu:-

    * 29,432,000 hits from Ubuntu

    * 624,000 hits from Linux Mint

     

    There’s a hralthy 68,000 hit increase from Linux Mint users – certainly indicating a surge in its use. But look at Ubuntu – almost 13 million hits up from October, which, perhaps not coincidentally, saw the release of Ubuntu 11.10

    Linux Mint is definitely, one of the best Distros out there, which comprises huge dedicated developers swarm and a group of loyal followers thoughout the world, but getting on to a conclusion that Ubuntu is loosing it’s ground just because of it’s “co-distro” will not be a reasonable and noble effort.

  • Enable minimize, maximize button, Gnome 3 on Ubuntu 11.10

    Enable minimize, maximize button, Gnome 3 on Ubuntu 11.10

    After having an native option to upgrade the unity with New Gnome 3 with one click, thousands of Ubuntu users did the same. There are many who doesn’t like it and on the other side there are thousands who love the new Gnome interface. There are few glitches user think Gnome shouldn’t have. But, Eventually they figure it out that it has been hidden intentionally. One of it is missing Minimize and Maximize button.

    Yes, you heard me right. The new Gnome 3 for Linux doesn’t incorporate the Minimize and Maximize button by default. You have to enable them from the advanced settings. Well, the question is how you can find the advanced settings option in your Ubuntu?

    Actually, we are talking about the “Ubuntu Tweak” Repository here. You can download Ubuntu Tweak from software center. or just click here.

     

    Advanced Settings 029Instructions :

    1. search for “advanced Settings” in your Computer where you have installed Gnome.

    2. Click on “Shell” from the list on the left-hand side of the window.

    3. You will find an option “Arrangement of buttons on Titlebar” With the dropdown menu.

    4. choose the option suitable for you.

    5. Close “advanced Settings” Window.

    6. Done.

  • Things you can do after installing Ubuntu 11.10

    Things you can do after installing Ubuntu 11.10

    Ubuntu 11.10 is quite a large over-ripped (and wrapped) version of it’s predecessor. The new Ubuntu 11.10 Oneiric ocelot was released on Oct 13th 2011. I have been using Ubuntu 11.10 since it’s release (and even before, when alha 1 was released). Ever since the arrival of Unity, many new and old Ubuntu users are looking for ways to improve the functionality aspect of Ubuntu and customize the Unity environment to their respective needs. Here are the few tips and tricks you can opt for, for your new Ubuntu 11.10 :

     

    1) Installing Restricted extras during Installation

    * Starting from Ubuntu 11.04 release, you can install restricted codecs package(which include Adobe Flash, MP3 codecs and such) during installation of Ubuntu OS itself.

    Screenshot* Notice the arrows pointing to the boxes in the screenshot above. If you tick both of them during the Ubuntu installation process(make sure you are connected to the internet before doing so), restricted extras package will be installed automatically and you will be able to play mp3’s and watch flash videos(YouTube videos for example) right after Ubuntu installation is complete.

    * But there is a catch. If you have a slow internet connection(which is very rare these days), ticking the boxes shown in the screenshot above will unnecessarily lengthen the installation process. I for one prefer to do all that after installing Ubuntu. If you are like me, the next two steps are for you.

     

    2) Update Repositories

    * After you install brand new Ubuntu 11.10, the first thing you need to do is to update repositories and make sure you have the latest updates installed(Like I said before, you need to do this only if you haven’t ticked the boxes shown in the above screenshot).

    *Open Terminal(Ubuntu 11.10 Keyboard Shortcut: Ctrl + Alt + T) and copy-paste the following command into Terminal. 

    sudo apt-get update && sudo apt-get upgrade

    * Done. Ubuntu repositories have been successfully updated.

     

    3) Install Ubuntu Restricted Extras

    * Install the “ubuntu-restricted-extras” package. This will enable your Ubuntu to play popular file formats like mp3, avi, Flash videos etc. Click Here OR simply copy-paste the command below into Terminal to install the package(You need not do this also if you have ticked the ‘right’ boxes).

    sudo apt-get install ubuntu-restricted-extras

    * Done.

     

    4) Enable Full DVD Playback(Dual Layer DVD Support)

    * Though installing the restricted extras package will solve most of your problems, you may not be able to play dual layer dvds yet in your Ubuntu.

    * For that, you need to install libdvdcss2 package from medibuntu repositories. Simply do the following in Terminal.

    sudo wget –output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list && sudo apt-get –quiet update && sudo apt-get –yes –quiet –allow-unauthenticated install medibuntu-keyring && sudo apt-get –quiet update

    sudo apt-get install libdvdcss2

    * Done.

     

    5) Check for Availability of Proprietary Hardware Drivers

    driver copydrivers ubuntu1110
    * In my case, all the hardware drivers including graphics, sound and wireless drivers were enabled automatically(though, as you can see, I still have a proprietary wireless driver on offer, which I have not activated). But this may not be the case with everyone.

    * If you are among the not-so-lucky, open Unity dash (Ubuntu 11.10 Keyboard Shortcut: Super key) and search for ‘Additional Drivers’ application.

    * Check for additional drivers available and activate the ones you want. In 90% of the cases, this will do the trick. Those who were not able to get their hardware drivers enabled yet will have to do fair amount of digging through ubuntuforums.

     

    6) Install Compiz Config Settings Manager

    digitfreakccsmCompizConfig Settings Manager 019
    * Compiz desktop effects are available in your Ubuntu by default and if you have any kind of 3D acceleration available(graphics driver ie), you are good to go with Compiz.

    * Now to tweak Compiz desktop effects in Ubuntu, you need to install “compizconfig-settings-manager” package. Click Here OR simply copy paste the following command into Terminal to install “compizconfig-settings-manager”.

    sudo apt-get install compizconfig-settings-manager

    * Done. Compiz Config Settings Manager(CCSM) is significant as far as Ubuntu 11.10 Oneiric Ocelot is concerned. We will get to that later on.

     

    7) Essential Ubuntu Unity Keyboard Shortcuts

    * Productivity can be increased significantly in new Ubuntu Unity desktop if you know the essential Unity keyboard and mouse shortcuts. Here are some of the most important among them.

    * Super Key(Windows Key) – Opens dash.

    * Hold Super Key and hit 1, 2, 3 etc – Open an Application from Launcher. When you hold the Super Key, specific numbers will be displayed in order above each application.

    * Alt + F1 – Put keyboard focus on the Launcher, use arrow keys to navigate, Enter key launches the application, Right arrow exposes the quicklists if an application has them.

    * Alt + F2 – Opens dash in special mode to run any commands.

    * Super + A – Opens up applications dash.

    * Super + F – Opens up files and folders dash.

    Super + W – Spread mode, zoom out on all windows in all workspaces.

    * Super + D – Minimize all windows(acts as Show Desktop). Hitting it again restores them.

    * Super + T – Opens trash can.

    * Super + S – Expo mode (for everything), zooms out on all the workspaces and let’s you manage windows.

    * Ctrl + Alt + T – Launch Terminal.

    * Ctrl + Alt + L – Lock Screen.

    * Ctrl + Alt + Left/Right/Up/Down – Move to new workspace.

    * Ctrl + Alt + Shift + Left/Right/Up/Down – Place window to a new workspace.

    * F10 – Open the first menu on top panel, use arrows keys to browse across the menus.

     

     Mouse Shortcuts/Tricks for Ubuntu Unity

    * Clicking and holding an icon and then dragging it around will allow you to reorder it on the launcher. You can also drag it off to the right of the launcher to move it around. Note that you need to make an explicit movement to the right to move the icon off the launcher before you can move it around.

    * Dragging and Dropping an icon into the trash can will remove it from the Launcher.

    * Moving and holding the cursor on the left side for a few seconds will launch Unity dock.

    * Moving the cursor to top-left corner(near Ubuntu icon) will launch Unity dock as well.

    * Scrolling the mouse wheel while over the Launcher scrolls the icons if you have too many and need to move around quickly.

    * By Scrolling the mouse wheel while over the Sound icon on top panel helps you increase or decrease system volume.

    * Middle click on an application’s launcher icon – Open a new instance of the application in a new window. Very useful at times. In laptops with touchpads, hitting left/right click buttons together is akin to middle click.

    * Maximizing – Dragging a window to the top panel will maximize it.

    * Restore/Unmaximize – Dragging the top panel down OR double clicking on the top panel will do.

    * Tiling – Dragging a Window to the left/right border will auto tile it to that side of the screen. One of the highlights of new Unity experience.

     

    And Some Useful Window Management Shortcuts(Generic)

    * Alt + F10 – Toggle between Maximize/Unmaximize current window.

    * Alt + F9 – Minimize current window.

    * Alt + Tab – Toggle between currently open windows.

    * Alt + F4 – Closes current window.

    * Alt + F7 – Moves the current window(both keyboard and mouse can be used).

     

    8) Enable Transparency for Unity Top Panel

    ccsmCompizConfig Settings Manager 021
    * Launch CCSM. Hit Super + a and search for CCSM.

    * After launching CCSM, select Ubuntu Unity Plugin from ‘Desktop’ category. Now choose the Experimental tab from above.

    * There you will see the ‘Panel Opacity’ option. Change it to the value you like.

     

    9) Increase/Decrease the Launcher Icon Size

    CompizConfig Settings Manager 021* Just as before, Launch CCSM(Super + a and search for CCSM) and then browse to Ubuntu Unity Plugin. Choose ‘Experimental’ tab.

    * Adjust the value of ‘Launcher Icon Size’ by simple scrolling. The default value of ‘Launcher Icon Size’ is 48, but I like it around 40 for my laptop.

     

     

    10) Change Desktop Size

    * By default, Ubuntu 11.10 Oneiric Ocelot gives you four workspaces to play around. Keyboard shortcut for activating the four workspaces is Super + s. Now, if you want to increase/decrease that number do the following.

    * Launch CCSM yet again, and select General Options from the category ‘General’. Select the tab ‘Desktop Size’ and choose the values you want. Simple as that.

     

    11) Add your Favourite Places As Quicklist for Home Icon in Unity

    Unity quicklistsQuicklists are something that I thought would be included as a default feature in Ubuntu 11.10 Oneiric Ocelot(at least some of them). But that didn’t happen. Home Menu quicklist in my opinion, is a must have feature(see screenshot to know how it will look like). Follow the steps to add your favorite places as quicklists.

    * Copy ‘Home Folder’ launcher file to your home directory. For that, you need to open Terminal(Unity Shortcut: Ctrl + Alt + T) and copy-paste the following commands.

    cp /usr/share/applications/nautilus-home.desktop ~/.local/share/applications

    * Open the file in your favorite text editor. I am using Gedit here.

    gedit ~/.local/share/applications/nautilus-home.desktop

    * Now replace the content of the file with the following text.

    [Desktop Entry]

    Name=Home Folder

    Comment=Open your personal folder

    TryExec=nautilus

    Exec=nautilus –no-desktop

    Icon=user-home

    Terminal=false

    StartupNotify=true

    Type=Application

    Categories=GNOME;GTK;Core;

    OnlyShowIn=GNOME;Unity;

    X-GNOME-Bugzilla-Bugzilla=GNOME

    X-GNOME-Bugzilla-Product=nautilus

    X-GNOME-Bugzilla-Component=general

    X-Ubuntu-Gettext-Domain=nautilus

    X-Ayatana-Desktop-Shortcuts=Videos;Documents;Music;Pictures;Downloads

    [Videos Shortcut Group]

    Name=Videos

    Exec=nautilus Videos

    TargetEnvironment=Unity

    [Documents Shortcut Group]

    Name=Documents

    Exec=nautilus Documents

    TargetEnvironment=Unity

    [Music Shortcut Group]

    Name=Music

    Exec=nautilus Music

    TargetEnvironment=Unity

    [Pictures Shortcut Group]

    Name=Pictures

    Exec=nautilus Pictures

    TargetEnvironment=Unity

    [Downloads Shortcut Group]

    Name=Downloads

    Exec=nautilus Downloads

    TargetEnvironment=Unity

    * And restart Unity. Hit Alt + F2 and run the following command to restart Unity.

    unity –replace

    * Done. If that doesn’t work, you might need to log out and log back in to restart Unity.

     

    12) Enable Uity Grab handles

    CompizConfig Settings Manager 022CompizConfig Settings Manager 023CompizConfig Settings Manager 024unity grab handles
    This is another feature that I thought would be included as a default. Unity grab handles are a easy and eyecandy way of resizing windows, better suited for touch screen devices though.

    * Launch CCSM(just search for CCSM in Unity Dash).

    * Make sure that the category Png(highlighted above) is ticked.

    * In the Uncategorized section at the bottom of CCSM, make sure that Unity MT Grab Handles is ticked as well. Click on Unity MT Grab Handles option now.

    * You will see that the Toggle Handles option is Disabled by default. Click on the Disabled button and tick the resulting Enabled box.

    * Hit Grab key combination button and select the shortcut you want. As you can see in the screenshot above, Control + Alt + g was my choice. Its up to you.

    * Done. Unity Grab Handles are enabled in Ubuntu 11.10 successfully.

     

    13) Install sysmonitor App Indicator

    Unity’s top panel is locked down and it is not easy to add apps to it anymore. App Indicators are an excellent way to extend the functionality of Unity top panel in Ubuntu Oneiric. And Sysmonitor application indicator is one of my favorite.

    digitfreak2Screenshot at 2011-12-15 025139
    * To install Sysmonitor Indicator in Ubuntu 11.10, you need to copy paste the following commands into Terminal.

    sudo add-apt-repository ppa:alexeftimie/ppa

    sudo apt-get update

    sudo apt-get install indicator-sysmonitor

    * Done. Now, simply launch Sysmonitor Indicator from Unity dash.

     

    14) Install Gnome Shell on Ubuntu

    Screenshot at 2011-12-09 112836
    Installing GNOME Shell in Ubuntu is not “mission impossible” anymore. Ubuntu 11.10 Oneiric Ocelot is GNOME 3.0 based and installing GNOME Shell in Oneiric is just a click away. Instead of one simple GNOME interface, now you have two, each one unique and special in its own way. Here is how you install it. Just search for ‘GNOME Shell’ in Software Center OR do the following in Terminal.

    sudo apt-get install gnome-shell

    Read How to Install Gnome 3 in Ubuntu 11.10, for more details and further configurations.

  • How to Get Gnome 3 On Ubuntu 11.10

    How to Get Gnome 3 On Ubuntu 11.10

    Gnome is getting a great shape and it is now stable and user-friendly. The best thing is that Ubuntu 11.10 + (one of Linux Member) can have the gnome interface without much hassle. There are no special tricks to do the specific job. You just need an internet connection and a brief knowledge (or work experience on Ubuntu OS).

    Ubuntu 11.10 finally provides Gnome installation through “ubuntu Software Center.” Curious users who wants to try the new Gnome 3 on their Ubuntu 11.10, can now go through the easy and safe steps to try out and install “Gnome-Shell”.

    This means that unlike previous releases of Ubuntu installing GNOME Shell in Ubuntu doesn’t require the addition of any extra ‘software repositories’, or the running of any dubious scripts: it can be installed directly from the Ubuntu Software Centre with a simple click.

     

    Click Here to Install Gnome Shell

    Gnome Extra’s

    To get the ‘best’ GNOME Shell experience in Ubuntu we should also install a number of additional ‘extras’.

    These include GNOME Contacts – a slick Google-integrated address book: –

    Contacts 002

    GNOME Sushi is a handy file preview tool integrates into Nautilus (the default file-manager). To preview an image, movie, audio track or text file just select it with your mouse or keyboard then tap the space key once to ‘peek’ inside: –

    Selection 005

    GNOME Tweak Tool lets you tweak the way GNOME Shell behaves. Whether you want to enable icons on the desktop, change the system theme, or adjust system font size, GNOME Tweak Tool lets you do it: –

    Advanced Settings 003


    Click Here to Install Gnome Extras

    Once all of the above applications have finished installing it’s time to dive on in to GNOME Shell. Hit the ‘Power Cog’ icon in the top right hand corner and choose ‘Log out’. Be sure to save any work or files before doing this.

     

    Enabling Gnome-Shell

    Now It’s time to rock-n-roll. follow the following simple steps toactivate gnome-shell on your Ubuntu 11.10 OS.

    1. At the login screen click the ‘cog’ icon to the right of your username

    2. Choose the session you want to log into from the menu. For GNOME Shell you’ll want to select ‘GNOME’

    3. Enter your password and login as normal

    shell-log-500x290
    And That’s it.  But wait you might feel that Gnome 3 windows are ugly. Because of black and white tint of colors on the file manager and other windows.

    The thing is that you didn’t enable the Gnome Default theme. You are still using the Ubuntu 11.10 “Unity” Theme. So the next step is to change the Default Unity theme to “Adwaita”  Gnome Theme. Here’s how:

    1. Open ‘System Settings’ from the furthest right-hand menu.

    2. In the window that opens we will select the ‘Appearance’ option.

    3. From here use the drop-down box at the bottom of the window to choose the ‘Adwaita’ theme.

    4. Log out and back in to see the theme take full effect.

    Appearance 006

    Here are some Final ScreenShots, This is what you’ll get on finalized installation.

  • How to install Firefox 8 on Linux Mint, Ubuntu, Debian, Fedora, Opensuse, … or any other Linux distribution.

    How to install Firefox 8 on Linux Mint, Ubuntu, Debian, Fedora, Opensuse, … or any other Linux distribution.

    firefox-4This howto explains how to install Firefox 8 on Linux distros, without replacing your current Firefox installation.

    Firefox 8 will be released on November 8, 2011.
    Firefox 8 Beta 6 has been released on November 3.

    More information on Firefox release dates, beta, aurora and nightlies on the official releases wiki.

     

    A. Install Firefox 8 in 5 easy steps

    1. Download

     

    Download the release from the official channels page:
    www.mozilla.com/firefox/channels/

    (if the link does not work, use Mozilla’s FTP server)

    A 64 bit build is also available in the x86_64 directory of Mozilla’s FTP.

    This how-to supposes that the downloaded file is saved in the “Downloads” directory situated in your home directory.

    2. Extract

    The downloaded file is a compressed .tar.bz2 archive. In case you want to Learn more on these extensions: tar, bzip2.

    To extract this juicy archive, open the Downloads directory. Look for a file named firefox-8.0.tar.bz2, right-click on it and select “extract here“.

    Alternatively, you can extract the archive from the command line:

    cd ~/Downloads/

    tar xjf firefox-8.0.tar.bz2

    For those interested, here are the tar  arguments used in the command:
    x : eXtract
    j : deal with bzipped file
    f : read from a file (rather than a tape device)

    The .tar.bz2 archive can now be deleted.

    3. Move to /opt

    External programs like LibreOffice, Google Chrome, Adobe reader, … are all installed in the /opt directory. If you want more info about why, check out these two links:
    Where to install my products on linux?
    Filesystem Hierarchy Standard

    If you already had a previous Firefox version installed in the /opt directory, remove it with the following command:

    sudo rm -r /opt/firefox

    Now move the firefox directory – which was created in your Downloads folder during extraction – to /opt:

    sudo mv firefox /opt/firefox8

    4. Set up symbolic links

    Depending on you usage pattern, follow the instructions for case 1 OR for case 2.

    Case 1: you want to use Firefox 8 as you default browser:

    “Backup” the old Firefox launcher:

    sudo mv /usr/bin/firefox /usr/bin/firefox-old

    Create a symbolic link pointing to the new Firefox version:

    sudo ln -s /opt/firefox8/firefox /usr/bin/firefox

    No need to update your icons/shortcuts, they should now launch the new version of Firefox.

    Your old Firefox version is still installed. If you want to use it, run firefox-old in a terminal or create shortcuts/icons referring to firefox-old.

    Case 2: you want to keep using your “old” Firefox by default:

    Create a symbolic link pointing to the new Firefox version:

    sudo ln -s /opt/firefox8/firefox /usr/bin/firefox8

    Launch the newly installed Firefox by running firefox8 in a terminal, or create shortcuts/icons referring to firefox8.

    5. Updates & Final

    Firefox 8 will manage its own updates independently of your system’s package manager, an download subsequent releases.

    There will be no need to repeat the whole “procedure”… Enjoy Firefox 8!

    B. Ubuntu’s case, Linux Mint and Debian

    1. Ubuntu: no ubuntu-mozilla-daily ppa!

    Many howtos on this subject will tell you to install Firefox pre-versions through Mozilla’s ppa ubuntu-mozilla-daily.

    Using this ppa will not only install the latest Firefox 10 nightly build, used to be called “minefield” – updated daily! It will also update your current Firefox and Thunderbird to test versions.

    These testing versions are not meant to be stable or usable.

    ? Avoid this ppa unless you know exactly what you’re doing!

    2. The Firefox Beta ppa: mozillateam/firefox-next

    The firefox-next ppa will replace your current Firefox installation with the current available version in Mozillas Beta channel. Simply run these two commands in a terminal:

    sudo apt-add-repository ppa:mozillateam/firefox-next
    sudo apt-get update && sudo apt-get upgrade

    You may also have a look at the Firefox Aurora ppa.

    Note: you can use only one of these three channels (Aurora, Beta, and Daily) at the same time!

    3. Official Ubuntu updates for Firefox (automatic)

    Since Ubuntu 11.04 “Natty Narwhal”, Ubuntu will update automatically to the newest stable Firefox version when it is released. (it may take a few days more, though) This is also valid for Ubuntu 11.10 “Oneiric Ocelot” and upcoming releases.

    5. Linux Mint 11, and Debian 6 “Squeeze”, …

    This howto has been tested with success on the following distributions, with Firefox 6, 7 and 8:

    Debian 6 “Squeeze”
    Linux Mint 10 “Julia”
    Linux Mint 11 “Katya”
    Ubuntu 10.04 LTS “Lucid Lynx” (Long Term Support, until April 2013)
    Ubuntu 10.10 “Maverick Meerkat” (support until April 2012)
    Ubuntu 11.04 “Natty Narwhal” (support until October 2012)
    Ubuntu 11.10 “Oneiric Ocelot” (support until April 2013)

    this installation procedure is reliable and should work with a wide range of distributions. Please share your experience with OpenSuse and Fedora in the comments.

    C. Uninstall/remove Firefox 8 (for non-ppa installations)

    Remove the Firefox directory:

    sudo rm -r /opt/firefox8

    You also should consider changing back or removing symbolic links which pointed to the old Firefox directory. Change back:

    sudo mv /usr/bin/firefox-old /usr/bin/firefox

    Or remove the firefox8 symlink:

    sudo rm /usr/bin/firefox8

    D. Run multiple profiles and instances simultaneously

    Problem: it is possible to run different Firefox versions with the same profile (profiles are compatible through major versions). However this is not very convenient, as Firefox will check the profiles extensions and plugins every time you start a newer or older version.

    Solution: create a profile for each Firefox version. Create new profiles with:

    firefox -no-remote -ProfileManager

    The -no-remote option starts a new instance of Firefox even if there is already a Firefox instance running. Use the -no-remote option to run Firefox 8 and Firefox 9 instances at the same time.

    Let’s say that you’ve created two profiles: ffox8_profile and ffox9-profile. You can start one instance of Firefox 8 and one instance of Firefox 9 with the following commands:

    firefox -no-remote -P ffox8-profile

    How to Connect Internet On Ubuntu (3G/UTMS/2G/GPRS)

    Ubuntu detects all the external media by its own automatically without any problem, however, it is not fairly possible to detect all the devices out there without any issues, some devices cannot be detected (which is very rare). Here is the instruction you can follow to setup a new connection for GPRS/3G/4G network configuration. To set up a new connection you can follow these steps.

    1. on the upper right corner of the screen click on a triangular shape which is the indicator or internet connections on Ubuntu just like on Windows or Mac.

    2. After clicking on it, go to “Edit Connections” and click on it.

    3. You will be greeted with a new pop-up window.

    4. Click on “Mobile Broadband” tab. Click on “Add” button.

    6. Choose you country

    7. choose your internet service provider. If it is not listed by default you can add manually. But most likely it will be there.

    8. Click “Continue” and then “Apply.”

    9. Go to the triangular icon we clicked at the beginning and select your connection from the drop down list. Ubuntu will connect to your ISP and viola you can now surf the internet without any problem.

    10. If you want to get your internet connected automatically at the system startup, Go to “Edit Connections” (that we visited before), click on “Mobile Broadband” tab, select your connection from the list and click on “Edit” button. In the Next window you will see a checkbox at the top tick the “checkbox” where it says “Connect Automatically” and you will get connected to your internet connection automatically at the system start up.
