Red Hat Bugzilla – Bug 113987
xscreensaver dies randomly
Last modified: 2007-11-30 17:10:35 EST
Description of problem:
xscreensaver dies randomly with both blank and gflux (and probably
other) screen savers.
Version-Release number of selected component (if applicable):
reproducible every other day with gflux as screensaver.
reproducible every 2 weeks with blank as screensaver.
Steps to Reproduce:
1. Configure xscreensaver. Make it require a password to unlock.
2. Walk away for a while.
3. Come back and see if the screensaver is running.
sometimes the screensaver is not running.
the screensaver should not die and should require a password to unlock
if locking is enabled.
some gdb output:
Core was generated by `xscreensaver -sync -verbose -no-capture -nosplash'.
Program terminated with signal 11, Segmentation fault.

I'm running Fedora Tettnang release as downloaded 2 weeks ago, and
this problem still seems to be there except it comes up more randomly.
And given that I run the machine 24x7 and have only seen the problem
when the saver kicks in, I have to assume that it only locks up the
machine if you try to use the machine while the particular SS is
active. i.e. if you let the problem SS run it's course (e.g. while
I'm gone all day) and let the next one start, it's fine. Maybe that's
an invalid assumption.
I've had it happen twice now. Sorry, don't recall which saver it was
either time. First time when I moved the mouse to deactive the saver
text appeared in the top left of the screen. i.e. it was console text
coming out over top of the X server as though X were not even running
if you get what I mean. I could still move the mouse and alt-tab
windows - for a bit. Then things locked up completely. But when I
hit the power button X came down and then I had the regular clean
Linux shutdown with all the "blah blah blah ..... [OK]"
The second time was just a few minutes ago and there was no console
text coming through, and it was hung tight from the beginning and the
power button seemed to initiate a shutdown but I didn't get all the
"blah blah blah ..... [OK]" - a few lines of shutdown text came up
then the power went out. On reboot filesystems were clean though.
I've got an Nvidea Gforce (440 I think) video card, and an ASUS mobo
either A7N8X-X or A7V8X-X don't recall of the top of my head.
I will disable OpenGL savers to see if that fixes it. Are they all
the ones that start with "GL"?
BTW, sorry but I entered the above text into another bug but this one
seems to be a much better fit.
do you run ldaps or any other unusual authentication methods?
i think the problems i was seeing are better described here:
Nope. I just have /etc/passwd. I only log in via SSH (no telnet) but
I don't think that should matter. In any case I've turned off all the
GL savers and we'll see what happens.
This appears to be a duplicate of bug 126428. Let's track the problem
*** This bug has been marked as a duplicate of 126428 ***
No, that's not at all what is happening to me. As noted, I leave my
machine on 24x7 and I have never had a problem with it after being
idle for hours on end. I get up in the morning and it's been sitting
there 7 or 8 hours and no problems. Get home from work and same
thing. I don't think this is a duplicate.
Actually, probably my bad. Reading the original report in this bug
report, the two are probably duplicates but my problem is something
else altogether so I probably should have started a new bug. But if
you feel my problem is closely enough related I supposed we could
track them together.
Yes, I'm sorry. I actually meant to address that message to Rob.
Your problem sounds like it may be an X problem. Did disabling the
OpenGL screensavers help you? Either way, could you post a new bug to
the xorg component? Thanks.
just to clarify my situation-
i desire a screensaver that locks my screen.
after having problems with the opengl screensavers dying randomly, i
switched to a blank screensaver. this successfully avoided bugs seen
in #113987 and #126428. however, another bug appeared when unlocking
the screen, #121734. i believe a similar problem causes gdm to crash
when ldaps is configured for authentication.
do you still think i should post a new bug to xorg? if not xorg, what
is an appropriate component to post #121734 to?
thanks for your help.
Comment 6 was supposed to be addressed to you, but comment 8 was
addressed to Alan.
You shouldn't need to do anything else right now, until more activity
occurs on the relevent open bugs.
Well, I've been running ever since with all the GLxzy screen savers
disabled, and have not had the problem again. It seems pretty clear
that's what it was since I used to get the hang once a day prior to that.
