Right after upgrading to kernel 2.6.15-rc5 things are getting better.
This is with 'Option "OldDmaInit" "true"' in my xconf file. (**) MGA(0): DPMS enabled (II) MGA(0): Using overlay video (II) MGA(0): X context handle = 0x1 (II) MGA(0): [drm] installed DRM signal handler (II) MGA(0): [DRI] installation complete (II) MGA(0): [drm] Mapped 128 DMA buffers (II) MGA(0): [drm] dma control initialized, using IRQ 7 (II) MGA(0): Direct rendering enabled and this is from glxgears 1210 frames in 5.0 seconds = 241.964 FPS 1206 frames in 5.0 seconds = 241.097 FPS 1206 frames in 5.0 seconds = 241.014 FPS 1207 frames in 5.0 seconds = 241.209 FPS 1207 frames in 5.0 seconds = 241.253 FPS 1206 frames in 5.0 seconds = 241.181 FPS However the cogs turning when glxgears are running are VERY slow a lot slower than I am used to and the 241FPS is slightly down on 311FPs that I used to get (but why are the cogs moving so slowly as if direct rendering is turned off). Remove 'Option "OldDmaInit" "true"' and drm is disabled again. Dave ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
