I have a very similar card in my Gentoo laptop (Mobility Radeon 9700, |
34 |
I think maybe it's the same as 9600 but clocked higher). I tried KMS |
35 |
radeon driver but had some issues, maybe it was user-error but when I |
36 |
disabled KMS everything went back to normal. |
37 |
|
38 |
Otherwise if you want to stick with KMS all I can think of is to try |
39 |
different AccelMethod settings in your xorg.conf to see if you get |
40 |
better performance from one of them. I think maybe you need to disable |
41 |
console framebuffer as well, in case you're using one. |
