Description of problem:
The dri device "card0" has no other's access rights as follows.
crw-rw---- 1 root root 226, 0 Jan 11 09:12 card0
And OpenOffice1.1.3 programs open the device "card0", then
fail to open "card0".
This causes segmentation error and OpenOffice cannot start.
On the kernel-2.6.10-1.1053_FC4, "/dev/dri/card0" has access rights
crw-rw-rw- 1 root root 226, 0 Jan 11 09:30 card0
So, OpenOffice1.1.3 can start normally.
I attached strace log.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
2.start any OpenOffice1.1.3 Program
3.this symptom ocuured
Created attachment 109587 [details]
strace log of OpenOffice invocation
New facts I find.
1. kernel-2.6.10-1.737_FC3 is OK.
2. Editing /etc/udev/permissions.d/50-udev.permissions
dri/*:root:root:0660 ---> dri/*:root:root:0666
In this case, kernel-2.6.10-1.1076_FC4 is OK.
3. In kernel-2.6.10-1.737_FC3, even though not editing
50-udev.permissions, the sypmtom does not occure.
I don't know which has a problem kernel or OpenOffice.
when you get the segmentation fault, is there a kernel panic in the
output of 'dmesg' ?
660 is correct permissions for this devnode, as otherwise it would be
a security hole.
No, there is not a kernel panic.
