Hey boss!
Good to hear from you.
If I ignore the wiki method and try to run it directly from the same X session (from an X- or gnome-terminal), the screen blanks totally and I lose keyboard input completely -- not even Alt+SysRq+B interrupts properly to reboot, and I have to hard- or soft-reset the machine.
Just before it attempts to launch, I get about five or six error messages saying that they can't access /dev{/sound}/dsp ... which is strange, as most everything else (alsa and openal-related; other apps, that is) seems to be fine.
Following the wiki entry, I set up an alternate Xsession, changed the Xwrapper permissions, and when I try to login, I get a blank Xsession, with stderr showing the following:
AUDIT {date and time: process/thread #} X: client 1 rejected from local host
Xlib: connection to ":1.0" refused by server
Xlib: No protocol specified
waiting for X server to begin accepting connections
... which I take to mean that I need to add suitable permissions or something.
Hm.
Any advice you could provide would, of course, be much appreciated.
Cheers
Mass
