Background: This question is on the back of Nvidia X Server flickers, hangs and segfaults on start-up. I am able to start X only if I install the proprietary Nvidia graphics for my graphics card (say, nvidia-304) in one kernel (3.2.0-23-generic), then boot in a different kernel (3.2.0-57-generic). It clearly uses some fallback driver, but I can't understand if it's nouveau or something else.
EDIT1: As suggested:
liv@malou-laptop:~$ lspci -v
[..]
01:00.0 VGA compatible controller: NVIDIA Corporation G86M [Quadro NVS 140M] (rev a1) (prog-if 00 [VGA controller])
Subsystem: Lenovo ThinkPad T61
[..]
Kernel modules: nouveau, nvidiafb
[..]
But strangely, these modules don't seem to be in use:
root@malou-laptop:/home/liv# lsmod | grep -i nouveau
root@malou-laptop:/home/liv# lsmod | grep -i nvidia
Although they're clearly available:
liv@malou-laptop:~$ modprobe -l | grep nouveau
kernel/drivers/gpu/drm/nouveau/nouveau.ko
liv@malou-laptop:~$ modprobe -l | grep nvidia
kernel/drivers/video/nvidia/nvidiafb.ko
lspci -voutputsKernel modules: nouveau, nvidiafb. But strangely, these modules don't seem to be in use when checking withlsmod(see EDIT1). – landroni Jan 10 '14 at 10:17sudo apt-get install nvidia-current) and runsudo nvidia-xconfig, then reboot, the system crashes? – Ash Jan 10 '14 at 12:00nouveauis the kernel module name for the Nouveau drivers (see modified EDIT1), and it is missing fromlsmodoutput here. If I install the latest officially-recommended Nvidia drivers (nvidia-331) for my card, then the Nvidia X Server flickers, hangs and segfaults on start-up (see that question for details). – landroni Jan 10 '14 at 12:26Additional Drivers:nvidia-173,nvidia-304andnvidia-319, in addition to theproposednvidia-331; all with the same effect ofXcrashes. According to Nvidia's website, bothnvidia-304andnvidia-331should support my graphics card, but obviously something doesn't fly. – landroni Jan 10 '14 at 15:47/var/log/Xorg.0.logwhich driver is currently being used? From parsing the log, my hunch is that it tries in successionnvidia,nouveau,nv, and for various reasons fails to load any of those. Then defaults to eithervesaorfbdev, one of which works. But I'm not sure that I'm getting this right. – landroni Jan 11 '14 at 08:22
