Description Kevin L. Mitchell 2001-01-09 11:18:00 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.
Comment 2 Raul Acevedo 2001-01-15 04:21:06 EST
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
Comment 4 Raul Acevedo 2001-01-15 07:42:37 EST
Upgrading to XFree86-4.0.2-1 and xscreensaver-3.26-2 (using rawhide RPMs)
didn't help.

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...
Comment 5 Mike A. Harris 2001-02-17 11:47:31 EST
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.
Comment 6 Mike A. Harris 2001-03-17 15:45:09 EST
Please upgrade XFree86 to the latest Rawhide release.
