Red Hat Bugzilla – Bug 23659
X hang observed
Last modified: 2005-10-31 17:00:50 EST
I installed RedHat 7.0 on my machine yesterday. When I came in today,
the screensaver was not changing and would not put up a login screen.
In fact, X refused to quit on C-A-BackSpace, nor would it allow me to
switch to a virtual console. A remote login showed that X was running
at 99% CPU; xscreensaver-command -restart hung, as did chvt 1. It's
not clear where the problem was. This is a 7.0 install with all the latest
updates; architecture is i686, card is ELSA GLoria Synergy.
I've had X crash several times more. I've disabled a couple of screensavers
that seem to be implicated: Laser and Flow. I *think* they'll only crash the X
server if they're run immediately after another screensaver. This is a pretty
serious bug, leaving the machine in a state where I am forced to reboot it in
order to get anything done.
I have exactly the same problem: I leave my machine, I come back and X is
completely hung. A remote ssh showed X at 99% of the CPU; explicitly killing
X with -9 didn't help, init 3 didn't help, I had to reboot my machine.
Disabling xscreensaver fixes it; I'll try disabling the same xscreensavers
that klmitch mentioned and see if that helps.
I just installed RedHat 7 Saturday, and have been using RedHat 6.2 on this
machine since it came out without problems. I'm using a stock install with
all the latest updates. X driver is 3Dlabs Permedia2 (glint) for Diamond
Fire GL 2000. PII 400Mhz (i686), 256M RAM.
I can reliably reproduce the problem by using "Laser" as the screen saver in the
Control Center, then clicking on the Lock button in the panel (or
-activate). The Laser saver starts, then X freezes after only a couple of
Upgrading to XFree86-4.0.2-1 and xscreensaver-3.26-2 (using rawhide RPMs)
I forgot: I don't have a completely stock install, I am using Helix,
i mean, Ximian GNOME. I doubt that's relevant, but just in case...
TO the original reporter, please (as always) attach X server error logs
and X configuration file to bug report. I have no idea what an Elsa Gloria
Synergy is. What I need to know should be in the server log though.
Please upgrade XFree86 to the latest Rawhide release.
