There were too many changes for me: upgrade of gcc to 4.3.2, and configuration of hal (a difficult thing to do on a laptop at the moment). What really slowed me down was that for some unknown reason my windowmaker was completely messed up and took me almost a day to get it fixed.
Back to the glxgears problem. This is critical for me since my ooimpress presentations have embedded animated gifs and they play really really slow under slideshow after the xorg upgrade. A random run of glxgears gave me this clue (go figure; I must have ran glxgears a hundred times before I saw this message) -> glxgears get fences failed: -1 param: 6, val: 0 298 frames in 5.0 seconds = 59.518 FPS 297 frames in 5.0 seconds = 59.293 FPS 297 frames in 5.0 seconds = 59.281 FPS do_wait: drmWaitVBlank returned -1, IRQs don't seem to be working correctly. Try adjusting the vblank_mode configuration parameter. Googling vblank_mode on the web I came across this web site http://en.gentoo-wiki.com/wiki/Intel_GMA which is pertinent to my hardware and kernel/drivers. Therefore if I do -> vblank_mode=0 glxgears ATTENTION: default value of option vblank_mode overridden by environment. get fences failed: -1 param: 6, val: 0 4418 frames in 5.0 seconds = 883.510 FPS 4490 frames in 5.0 seconds = 897.871 FPS 4491 frames in 5.0 seconds = 898.054 FPS 4481 frames in 5.0 seconds = 896.043 FPS 4382 frames in 5.0 seconds = 876.251 FPS I get much better performance as I used to have before the xorg upgrade. This is where I am now trying to gather information on how to deal with dri and vblank_mode settings. Hope this helps. -- Valmor
