When I give in this command to find out which graphic card is present in my laptop working on Ubuntu 12.10:
lspci | grep VGA
I get the following result:
00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09)
01:00.0 VGA compatible controller: Advanced Micro Devices [AMD] nee ATI Caicos [Radeon HD 6400M/7400M Series]
From the following link I read that there is something called integrated graphic card and a "discrete" one;
How to manage graphics cards?
Please correct me if my logical consequences are not right
I assume that I have to install a driver for the discrete graphic driver. I have been trying to install a graphic driver for many times but I didn't manage it at all.
I've seen that many people have problems installing a working graphic driver and I did read many questions and followed many many suggestions but the results were merely the same;
You could read at booting when I tried to install the propriatery AMD graphic driver - as example from the Software Center :
The disk drive for /dev/mapper/cryptswap1 is not ready yet or not present
Can someone give me a hint to install the correct propriatery graphic driver for my graphic card?
