since my last posting the ‘hp elitebook 8530w’ kept crashing quite often, when doing a resume after pm-suspend. i think i found a cure. disabling ‘compositing’ using:
- kde – system settings – desktop – ‘enabled desktop effects’
made it work. but for some unknown reason there were these random crashes when resuming.
it is NOT enough to disable this in kde as for some reason, it sometimes got reenabled without my influence (i don’t have any clue why). so today i tried to find a way to make these crashes reproducable: with some good results.
the problem was definitely related to ‘compositing’ (or AIGLX?) so i remembered the times when the ‘compositing’ extension was disabled by default, maybe for good reason?
i disabled it by editing xorg.conf:
Section “Extensions”Option “Composite” “Disable”EndSectionSection “ServerFlags”Option “AIGLX” “off”EndSection
after a restart of xdm with this new settings i could not get it to crash as i did before. that is good news to me! maybe it’s time to test x11-drivers/nvidia-drivers-256.35 again!
right now i’m using =x11-drivers/nvidia-drivers-195.36.24 with 2.6.34-gentoo-r1 with this graphics card:
01:00.0 VGA compatible controller: nVidia Corporation G96M [Quadro FX 770M] (rev a1)
i also have 2d and 3d acceleration running. *yepee*
21.09.2010 this is so strange, i still receive regular crashes on ‘resume’ but maybe they are not directly related to the nvidia module. the problem is that this is very hard to debug as there is no graphical output nor any log files to start with …
