I have installed Ubuntu 12.10 on my system with USB. After installation it seems that the system is slow. I think the problem is with its graphics card driver. The system that I am using is an HP Pavilion DV6 laptop with a Radeon HD 6400M/7400M ATI graphics card.
When I ran
lspci -nn | grep VGA in the terminal the output was:
00:02.0 VGA compatible controller : Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0116] (rev 09) 01:00.0 VGA compatible controller : Advanced Micro Devices, Inc. [AMD/ATI] Seymour [Radeon HD 6400M/7400M Series] [1002:6760]
I already tried running
sudo apt-get install fglrx fglrx-amdcccle and that made the Unity launcher disappear, so I reinstalled Ubuntu 12.10. How can I install the graphics driver for my HP Pavilion DV6 laptop without losing the Unity launcher?
Now its showing X.org X server AMD/ATI dsplay driver. But still its showing slow and the laptop temperature is increasing and after sometime laptop goes to shutdown automatically.
