Same here the upgrade to xorg-server-1.5.x introduced lots of surprises. |
26 |
There were too many changes for me: upgrade of gcc to 4.3.2, and |
27 |
configuration of hal (a difficult thing to do on a laptop at the |
28 |
moment). What really slowed me down was that for some unknown reason my |
29 |
windowmaker was completely messed up and took me almost a day to get it |
30 |
fixed. |

Back to the glxgears problem. This is critical for me since my ooimpress |
33 |
presentations have embedded animated gifs and they play really really |
34 |
slow under slideshow after the xorg upgrade. A random run of glxgears |
35 |
gave me this clue (go figure; I must have ran glxgears a hundred times |
36 |
before I saw this message) |
37 |
|
38 |
-> glxgears |

Try adjusting the vblank_mode configuration parameter. |
46 |
|
47 |
|
48 |
Googling vblank_mode on the web I came across this web site |
49 |
|
50 |
|
51 |
http://en.gentoo-wiki.com/wiki/Intel_GMA |
52 |
|
53 |
which is pertinent to my hardware and kernel/drivers. Therefore if I do |
54 |
|
55 |
|
56 |
-> vblank_mode=0 glxgears |
57 |
ATTENTION: default value of option vblank_mode overridden by environment. |

I get much better performance as I used to have before the xorg upgrade. |
67 |
This is where I am now trying to gather information on how to deal with |
68 |
dri and vblank_mode settings. |
69 |

Hope this helps. |
