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
