Re: [opensuse] display freezes on "log out" OK on shutdown. What to check?

Mates,

Suse 10.3, kde, compiz. The screen freezes on log out and will not
return you to the login prompt. You can see the text screen from boot
flash just for a second before kdm tries to restore the login. The
the screen goes blank. (not totally black like off, the display is
still active, it's just black) The system is hardlocked and must be
hard reset. ctrl+alt+[either del or backspace] has no effect. Lockup
occurs regardless of whether the WM is kwin or compiz. The logs are
empty.

When this happens, have you tried accessing a virtual console
(CTRL+ALT+N where N is 1 through 6) to log in an run diagnostic or
restorative commands? If you cannot, have you tried logging in via ssh
for the same reason?


What should I check or what link can I read to start to sort this
out? thanks.

Is this repeatable, or has it just happened once? If repeatable, does it
occur 100% of the time?

If it's a one-time (or rare) thing, it might be the Reiser FS hang
problem (Bug 336669:
<https://bugzilla.novell.com/show_bug.cgi?id=336669>), but this never
manifests itself the same way twice, other than that one or more
processes end up permanently hung in a D wait state. It seems to strike
any process at any time and is (my hunch) a concurrency bug. Do you
have a HT, multi-core or multi-processor system?
