Ubuntu 12.04 and ATI driver 100% CPU usage bug makes it useless on laptop
I am unfortunate enough to be suffering from this bug:
As soon as the screen goes into standby mode the compiz maxes one of the cores of the CPU. This of course drains the battery in no time flat :(
When I use the opensource driver this issue doesn't exist but I want to play games with a proper frame rate in Linux and especialy seeing as steam is coming to Linux this will be a big issue for all using laptops and ATI display cards...
I am not sure if the problem is compiz or ATI related. The same thing happens when using cinnamin on Mint 13 so it definetly is some incompatibility in compiz and the ATI driver.
I installed the driver via the software centre and by following these steps:
All of them gives the same results...
