Nalin, George - is the problem here consolehelper or gdm? Most likely gdm. The problem is that there are many races and it's possible that the pam_close_session was not called in that case. This should be fixed in the newest devel version, but not in the stable version. This should be now fixed in upstream gdm 2.4.1.5 (stable) which I released today. We've upgraded, so this is likely fixed in RAWHIDE. Does it work for you? I've been using Redhat 9.0 for several months with gdm-2.4.1.3-5.1. This version does not behave in the same way; a simple ctrl+alt-bs user exit will not leave the sound device (an others) in an unusable state. However, if the user X session crashes the same problems can still occur, sometimes. e.g. the commercial demo version of Tux racers is particularly prone to causing the problem. Can I use gdm 2.4.1.5 on RH 9? If so I'll try and that and see what happens with Tux racers.... *** This bug has been marked as a duplicate of 134941 *** Changed to 'CLOSED' state since 'RESOLVED' has been deprecated. |
From Bugzilla Helper: User-Agent: Mozilla/5.0 Galeon/1.2.6 (X11; Linux i686; U;) Gecko/20020830 Description of problem: If a user exits the gnome desktop using ctrl-alt-backspace (may be because an application has locked), when another user tries to login, permissions on devices are still held by the previous user. In particular, the sound devices. If you have a mixer applet on your panel, you get an error dialogue box with the message "Couldn't open mixer device /dev/sound/mixer". Killing any hung processes from the previous user does not help. The only solution I have found is to reboot. Is there some /etc/init.d/ typer service I can restart to reset the permissions? Using Redhat 8.0, fully patched via redhat network. Version-Release number of selected component (if applicable): How reproducible: Always Steps to Reproduce: 1.login to gnome desktop as user A 2.exit desktop using ctrl-alt-backspace 3.login to gnome desktop as user B Actual Results: user B, who has a mixer applet, gets "Couldn't open mixer device /dev/sound/mixer" error and has no access to sound. Expected Results: user B should have access to sound as normal Additional info:
