So, i've just installed Debian 6.0.4 as a dual boot set up, so I still have windows if need be.
I havent had this problem with any other linux distro I've used (specifically Mint OS and Ubuntu).
Having installed Debian on my i5 2500k based system, and installed necessary graphics drivers to allow my radeon 6950 to work, I notice some terrible performance problems.
Moving windows around the screen causes phenomenal tearing (I've played around with the ATI console settings, but its still very slow)
So, I launch System Monitor to try see whats going on, and although System Monitor doesnt allow me see Gfx card usage, I can see a huge spike in CPU usage when I move windows around.
Playing a video (albeit, not a HD stream) caused barley a spike in my CPU usage.
Does my x window system not know about my graphics card? If so, how do I let it know!!
Any other help ye can give me would be great.
EDIT: Also, If ye need any more info, feel free to ask!
Its pretty late here, so I could be missing something simple... Also, I'm going to be sluggish in work tomorrow as a result of this...
Anyway, cheers in advance!
