Bug 1658 – gdm takes ownership over sound and nvidia files in /dev

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Artur Brodowski 2002-04-10 16:49:07 UTC]

could anyone try to reproduce this:
when i log on in gdm as a normal user, /dev/nvidia*, /dev/console and /dev/snd*
are not owned by root anymore, but by this user (first one that logs on). i
tried to chown root manually (back to root), but again, after restarting gdm and
logging on, ownership changes. this is not fixed when i close a gnome-session
kernel 2.4.19-r1, alsa sound drivers, nvidia 1.0-2880
portage version 1.8.19
gdm 2.2.5.4-r5, gnome-things are also the newest ones
this might be makedev problem, not gnome's, i'm no hacker to figure it out.

i guess the real problem with this issue shows up when many users log on the
same machine.first login gives the rights/ownership to the user so for him
desktop works fine. but after his logout rights are not back to normal
(root/audio), so next user cannot use sound (/dev/mixer, /dev/dsp and others
won't open). for single user this is no real bug, unfortunately i share my dektop :(
this rights switch was alos reproduced on mckennedy's box, i talked to him on
#gentoo the other day.

solved. the problem was not actually on gdm/gnome-session side, it was a libpam
upgrade that caused it (the rights for 'sound' in /etc/security/console.pref
changed from 660 root.audio to 600). i edited the file, everything is back to
normal.

Is this actually fixed?  I just ran into the problem on a box with sys-libs/pam-0.77 - the permissions for sound in /etc/security/console.perms are still 600.

Never mind.  Just ran across bug 31877, which seems to be closer to the actual problem, and is still open.
