I have ubuntu 32 bits.
My initial problem is freeze of xorg with
[ 31.514] (EE) CHROME(0): [drm] Failed to open DRM device for pci:0000:00:01.0: No such file or directory message in Xorg.0.log file
xorg.conf is :
Section "Device" Identifier "carte1" Driver "openchrome" # zotac BusID "PCI:00:01:0" # zotac EndSection
Driver "vesa" works, but is limited to 1024x768 mode.
dmesg seems strange :
[ 8.539958] [drm] Initialized drm 1.1.0 20060810 [ 10.890285] EXT4-fs (sda1): ....
There are more 2 seconds between drm initialisation and the next message. And no others drm posts then. drm kernel module is not loaded, despite it is possible manually with modeprobe.
It seems drm have some special file to create and don't make them.
I've disabled dri module at xorg.conf, but xorg stay frozen.
Thanks for your help
It's the same without xorg.conf.
I really think it's drm issue. On my thinkpad dmesg says :
[ 12.139863] [drm] Initialized drm 1.1.0 20060810 .... [ 12.188649] i915 0000:00:02.0: irq 43 for MSI/MSI-X [ 12.188657] [drm] Supports vblank timestamp caching Rev 1 (10.10.2010).

and I can find two special files :
crw-rw----+ 1 root video 226, 0 juin 18 13:42 card0 crw-rw---- 1 root video 226, 64 juin 18 13:42 controlD64
ZOTAC's dmesg gives only drm initialisation message, without gpu initialisation massage, as at thinkpad's listing at
[ 12.914841]. The special dri files are not at ZOTAC, neither.
