I made a partition on my desktop pc, 100 GB and installed Ubuntu 12.10 on it. It was pretty slow first thought it had to install updates or something, so I rebooted it. Now after the login it looks like everything freezes, I can move my mouse only, but that's it! I can see my desktop and launcher, but the task bar doesn't display time and misc system info, only a black bar, I downloaded the Android SDK pack and installed vlc media player before I rebooted.

My computer info:

  • 1 TB HDD
  • 8 GB ddr3 RAM
  • ATI Radeon 4890 videocard (1 GB)
  • AMD Phenom 2 x4 black 3, 2ghz CPU (64 bits)

Have you installed drivers for your graphics card? –  Seth Nov 26 '12 at 23:52
    
No I didn't. I already uninstalled the OS. I salvaged my dad's old pc its HDD and placed it inside my computer. Installed Ubuntu 12.10 x64 from cd onto the 'new' HDD (160gb). Installation went flawless, but after the installation I had to log in and the same thing happened; I can't do anything... –  Mystogan Nov 27 '12 at 1:09
    
Try to use GNOME classic (gnome-shell), this could be a video driver issue. –  Terry Wang Nov 27 '12 at 1:30
    
Ok, thanks for your comments. Can I do this during/before my login? And how can I download a videocard driver through this OS? –  Mystogan Nov 27 '12 at 1:35
    
Use sudo apt-get install jockey-gtk to install a program called 'additional drivers', use this to install drivers. –  Seth Nov 27 '12 at 3:30

Note: If you can boot into Ubuntu just fine, skip to step 8.

If this is a video card issue following these steps should fix the problem (make sure you have internet):

  1. Boot as far into Ubuntu as you can

  2. Press Ctrl+Alt+F1 to open a terminal.

  3. Log in with you username and passoword
  4. Run sudo apt-get update

  5. Then

    sudo apt-get install gnome-session-fallback 
    

    (this one will take a while) Note: you might be asked which display manager you want to use, select 'lightdm'

  6. After all that is finished run sudo reboot now which will reboot your computer

  7. At the login screen, click on the ubuntu logo, in the top right corner of the window, and select "GNOME Classic" click OK, and login.

8. After you have logged into Gnome Classic, open 'Software Center' enter image description here 9. Click 'Edit' from the menu and select 'Software Sources' 11. Open the 'Additional Drivers' tabenter image description here 12. Select the driver you want and click 'Apply Changes' 13. Reboot.

Jockey-gtk has been integrated into software sources inside the software center.

So in 12.10 you change drivers by:

  1. Opening software center

  2. Clicking 'Edit' --> 'Software Sources'

  3. Opening the 'Additional Drivers' tab

  4. Selecting the driver you want and clicking 'Apply Changes'

If the above steps don't fix the problem, then your graphics card is probably not supported.

In this case you have four options:

  1. You can install Ubuntu 12.04 LTS (where I think your graphics card is still supported)

  2. You can continue to use Gnome Classic

  3. You can use Xubuntu by running sudo apt-get install xubuntu-desktop or installing from scratch.

  4. Or you can try Lubuntu by running sudo apt-get install lubuntu-desktop or installing from scratch.

Kubuntu is also worth mentioning, but I'm not sure it will work without drivers. You can try though. sudo apt-get install kubuntu-desktop

Wow, thank you. I can't find the 'additional driver's program in the software centre (installed). If I download it through Firefox it says it has already been installed. –  Mystogan Nov 27 '12 at 9:31
    
Oh, sorry jockey-gtk has been removed from 12.10. For the time being try jockey-kde –  Seth Nov 27 '12 at 14:41
    
Thank you for your time and great explanation iSeth. It is weird, I installed the jockey-kde , but it doesn't show any drivers. Look at this: i.imgur.com/5lKJU.jpg [IMG]i.imgur.com/5lKJU.jpg[/IMG] –  Mystogan Nov 28 '12 at 0:17
    
Can you post more info about your machine? e.g. Make and Model? I'm afraid your graphics card is not supported in 12.10. It should work on 12.04 though. See here and here –  Seth Nov 28 '12 at 0:59
    
I use the radeon HD 4850 1gb videocard –  Mystogan Nov 28 '12 at 1:00
