kernel-2.6.24-0.150.rc7.git4.fc9

xorg-x11-drv-i810-2.2.0-3.fc9
The same problem:
Section "DRI"
Mode 0666
EndSection
crw------- 1 root root 226, 0 Jan 14 22:30 /dev/dri/card0
Weird -- looks like duplicate of bug 245398, but that one is for F7. Just run strace to check what X server does with /dev/dri/card0...
strace -f X 2>&1|grep /dev/dri/
open("/dev/dri/card0", O_RDWR|O_LARGEFILE) = 13
open("/dev/dri/card0", O_RDWR|O_LARGEFILE) = 13
open("/dev/dri/card0", O_RDWR|O_LARGEFILE) = 13
open("/dev/dri/card0", O_RDWR|O_LARGEFILE) = 14
open("/dev/dri/card0", O_RDWR|O_LARGEFILE) = 14
No chmod calls...
If you want try this way please use remote shell because X under strace is very
slow.
Parts of my config:
$cat /etc/X11/xorg.conf |grep -C2 666
Section "DRI"
Mode 0666
EndSection
$ ls -l /dev/dri/card0
crw------- 1 root root 226, 0 Jan 15 04:17 /dev/dri/card0
$ glxinfo |grep -i DRM # non-root
libGL error: open DRM failed (Operation not permitted)
# glxinfo |grep direct # from root
direct rendering: Yes
Created attachment 291671 [details]
my xorg.conf (generated automatically by X without config)
as temporary bugfix i use crontab to update mode of /dev/dri/card0 every minute... Updated rawhide: xorg-x11-server-Xorg-1.4.99.1-0.19.20080107.fc9.i386 xorg-x11-drv-i810-2.2.0-3.fc9.i386 kernel-2.6.24-9.fc9.i686 Seems the problem is fixed right now But I even don't know who fix and which package was fixed. ;-) Tested with Mode 0666, Mode 0644, Mode 0466 etc. All ok. Closing the bug. |
Description of problem: Section "DRI" Mode 0666 EndSection Doesn't change mode of DRI device. glxgears failed with "permission denied error". Temporary solved by changin mode from root user before starting of X server. Xorg.0.log seems no errors! Version-Release number of selected component (if applicable): xorg-x11-server-Xorg-1.4.99.1-0.13.fc9 xorg-x11-drv-i810-2.2.0-2.fc9 kernel 2.6.23.1 (yeah not latest) Additional info: fc8's X server set mode with same xorg.conf without any problems
