From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; ja-JP; rv:1.7.5) Gecko/20041108 Firefox/1.0 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 as follows. 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): kernel-2.6.10-1.1076_FC4 How reproducible: Always Steps to Reproduce: 1.start kernel-2.6.10-1.1076_FC4 2.start any OpenOffice1.1.3 Program 3.this symptom ocuured Additional info:
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.
