compiz utterly slow after resume (intel integrated)

[sibidiba]

Binary package hint: xserver-xorg-video-intel

Compiz works on my Lenovo R61i with acceptable speeds. However, after resuming from suspend, it becomes utterly unresponsive. Even an expose or alt+tab takes up to seconds to show, desktop effects must be disabled as a result. Desktop applications are not affected, only compiz effects.

Architecture: i386
Distribution: current Jaunty
Uname: 2.6.28-13-generic
Intel Driver: 2:2.6.3-0ubuntu9.4
lspci: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 0c)
# glxinfo |grep render
direct rendering: Yes
OpenGL renderer string: Mesa DRI Intel(R) 965GM GEM 20090326 2009Q1 RC2 x86/MMX/SSE2

Sync to VBlank is disabled. I also would like to note, that switching to the text console is necessary after resume to switch on the monitor signal.

Hi sibidiba,

Please attach the output of `lspci -vvnn`, and attach your /var/log/Xorg.0.log (and maybe Xorg.0.log.old) file from after reproducing this issue. If you've made any customizations to your /etc/X11/xorg.conf please attach that as well.

Hi sibidiba,

This sounds a lot like an X performance issue particular to Jaunty which got solved in Karmic when we moved to the 2.6.30-rc2 (and newer X bits). Can you please test to see if Karmic solves this for you? Testing a LiveCD should be sufficient - you can get an ISO image of karmic (alpha-2 or newer) from http://cdimages.ubuntu.com/.
