gnome-screensaver crashes on start
Last modified: 2007-11-30 17:11:44 EST
Description of problem:
When trying to lock/blank the screen, gnome-screensaver dies with an X Window
Seems to happen consistently on updated FC6T3 (with exception of gsf-sharp and
hsqldb, which give me checksum errors from the mirrors.)
System is a Dell Latitude X1 laptop with an "Intel Corporation Mobile
915GM/GMS/910GML Express Graphics Controller".
Version-Release number of selected component (if applicable):
$ rpm -qf /usr/bin/gnome-screensaver
$ ldd -v /usr/bin/gnome-screensaver | perl -ne 's,^\s*(/.*):$,$1,g && print;' |
xargs rpm -qf | sort | uniq
Seems completely reproducible here, by trying to lock the screen using main menu
-> "Lock screen".
Screen turns black briefly, then returns to the Gnome desktop I came from.
A locked screen.
Attached is the output from "gnome-screensaver --debug --no-daemon" when I try
to lock the screen.

Can you please attach the output from the following? That will be a big help.
gdb --args gnome-screensaver --no-daemon --debug --sync
(gdb) break gdk_x_error
Make breakpoint pending on future shared library load? (y or [n]) y

(Doesn't look as if the breakpoint found anything to break...?)
I didn't think of checking with the out-of-the-box xorg.conf. Sorry about that.
I tested it now, and I couldn't reproduce this crash with the original config
file. I'm attaching my xorg.conf as well, in case anyone wants to look at it.

I think you may need to install the debuginfo rpms first. Can you try that?
Getting this backtrace will help a lot.
Some info here:
Particularly: gnome-screensaver, gtk+, gdk, glib

Thanks for the tip about the debuginfo packages. Here's the output from gdb
with debuginfo packages installed.
Thanks for the info.

Can you please attach a "diff -u" between your non-working xorg.conf and your
Actually, nevermind. The reason it didn't work with your posted xorg.conf is
due to having dual heads with different supported visuals. This should be fixed
in CVS and 2.16.1 (released later this week). Thanks.
Fedora Core 5 and Fedora Core 6 are, as we're sure you've noticed, no longer
test releases. We're cleaning up the bug database and making sure important bug
reports filed against these test releases don't get lost. It would be helpful if
you could test this issue with a released version of Fedora or with the latest
development / test release. Thanks for your help and for your patience.
[This is a bulk message for all open FC5/FC6 test release bugs. I'm adding
myself to the CC list for each bug, so I'll see any comments you make after this
and do my best to make sure every issue gets proper attention.]
Closing, as this bug went away when the versions with the mentioned fix made it
