I'm a newbie at ubuntu and i'm trying to learn how to use it but my graphics card is well known to have problems in linux. I've tried several drivers and the results were incredibly bad. I used open source drivers on ubuntu 12.10 but after software-update it never boots right (black screen and at the top of the screen just a smidge of the mouse pointer is visible) Also in system settings/details the graphics card is shown as "Unknown". I overcame this issue by installing fglrx drivers by this method : Sudo apt-get install fglrx-updates aticonfig --initial -f Then it booted allright but the performance was really bad. Desktop framerate drops from time to time and compiz uses high levels of CPU. In system Settings/details the graphics card is displayed as (VESA: CAYMAN) I think Vesa is the equivalent of windows generic drivers... I thought this was the reason why CPU load was high because Data being offloaded to CPU by GPU. I tried fglrx instead of fglrx-updates same result. I tried to use xorg crackers ppa (open source fglrx) which was referred to me in a topic here in ask ubuntu. It didn't boot , the same display black screen mostly just a line at the top where if you move the pointer to the top you can see a small part of the pointer.
I want to be able to use my system in Ubuntu "efficiently". So , HD6950 users who were able to use the card in ubuntu efficiently could you please direct me into the right direction ? Which driver do you use and what should my glxgears and fgl-glxgears scores be ?
My system is ; 16 GB DDR3 2133 MHZ Ram Asus Crosshair V Formula Amd FX-8350 CPU Amd hd6950 GPU
Thanks in advance.
