I'm new to Linux and recently switched to Ubuntu 11.04 due to my project requirement. My laptop has been freezing and going to black screen of death when I run anything related to display (Share desktop, stream video, etc). Today I went through the Ubuntu forum to install the appropriate graphic driver and, after doing it, I rebooted my PC. It gave an error before login saying "select the recovery mode" and after clicking OK, it didn't give the same error on reboot but I've lost the 11.04 graphical interface and all I see is the interface of Ubuntu v10 with slow visuals (even scrolling up/down on browser is really slow). For the reference, here's a desktop screenshot so that you can understand the situation. Also the laptop is overheating.

How can I fix this problem? How can i get the Ubuntu 11.04 view back?
I also tried Google, but couldn't find any issue like this.

Some general Information:

  • Laptop: HP TouchSmart TX2-1160ea
  • Processor: AMD Turion TX2
  • Memory: 4GB
  • OS: Ubuntu 11.04

Some debugging information::

$ report-hw | grep controller

Hmm. Why didn't I think about this. hah. Thanks for switching my light ON. May be because that forum caused me this problem and I trust meta stack, i came here instead of going anywhere else. –  Sam Scar Aug 17 '11 at 11:57

I had similar problems with my video card ATI/AMD Radeon HD6470M. Look through this source and follow an instruction how to install proprietary driver Catalyst/fglrx
Hope it will help to solve an issue

:- I tried the given link, doesn't seems to make any difference. give the same output on 'dpkg' run as above. Also, the UI stays like Ubuntu v10. Moreover, at this point of time, i can't reinstall the OS as i'm half way project. Any help on this? –  Sam Aug 18 '11 at 8:05
    
Did you remove previously attempted installing FGLRX/Catalyst as mentioned in "Removing the Driver" section before new installation ? –  Justas Aug 18 '11 at 9:57
    
Hi,Yes i did. Then installed. no go. –  Sam Aug 18 '11 at 13:27
    
your desktop screenshot looks like you login as Classic Gnome Desktop. Try to login in Unity - you've got this choice when login screen appears (in the bottom) and see if something changes –  Justas Aug 18 '11 at 15:21
    
if nothing changed, then the easiest way how to repair everything - reinstall OS :) You could back-up all your home directory and also applications settings (most of them). Here you can find a comparision of back-up tools : askubuntu.com/questions/2596/comparison-of-backup-tools I like Deja Dup and Back in Time. –  Justas Aug 18 '11 at 15:24
