[desktop-discuss] [osol-bugs] Sound doesnt work after i use "gdmflexiserver --xnest"

Arthur:

This problem was fixed in Nevada, but not S10.  Refer to bugster
bug #6406880.

The problem is that GDM shouldn't be calling logindevperm for Xnest
sessions.

If this is a serious problem for S10 users, then it could be
fixed if the issue were escalated.

There are a few workarounds you could do:

1) Modify /etc/logindevperm to set mode 0666 for /dev/sound.  This
    will allow all users on the system to always have access to the
    audio device.  This might not be desirable if you share the
    machine with other users.

2) Modify /etc/logindevperm to not set the mode at all for /dev/sound
    by commenting out that line.

    Then you could edit the GDM PreSession script to chown /dev/audio
    to the logging in user and set perms to 0600.  The GDM PostSession
    script could be modified to change it back to root ownership with
    0600 permissions.  If you only do the chown/chmod calls if DISPLAY
    is ":0", then xnest sessions won't change the audio device perms.

    This is perhaps better if you share the machine with multiple users
    and you only want the person on display :0 to have access.

    The GDM PreSession script is /etc/X11/gdm/PreSession/Default and
    the GDM PostSession script is /etc/X11/gdm/PostSession/Default
