Daniel, |
| 46 |
I'm seeing the same problem here and trying to follow my way |
| 47 |
through your kernel config changes. I don't think I have it yet on |
| 48 |
this box as I'm seeing a message about rendering being disabled in |
| 49 |
Xorg.log.0 |
| 50 |
|
| 51 |
c2stable ~ # cat /var/log/Xorg.0.log | grep render |
| 52 |
[ 29.017] (WW) RADEON(0): Direct rendering disabled |
| 53 |
c2stable ~ # |
| 54 |
|
| 55 |
|
| 56 |
even though glxinfo says it's enabled: |
| 57 |
|
| 58 |
c2stable ~ # glxinfo | grep render |
| 59 |
direct rendering: Yes |
| 60 |
OpenGL renderer string: Gallium 0.4 on softpipe |
| 61 |
GL_NV_blend_square, GL_NV_conditional_render, GL_NV_light_max_exponent, |
| 62 |
c2stable ~ # |
| 63 |
|
| 64 |
Anyway, I'm sure I'll figure it out but I'm curious how you measure |
| 65 |
that it's working up to it's potential. I'm getting less than 200FPS |
| 66 |
in glxgears. I get >2500 on a cheaper nvidia card so I'm certain this |
| 67 |
Radeon 300 can do better. |
| 68 |
|
| 69 |
What do you see in glxgears? |
| 70 |
|
| 71 |
Thanks, |
| 72 |
Mark |
