Public bug reported:
I have the release version of Gutsy running on a Dell Inspiron 6400 with
1280x800 main screen, and an Acer AL707 1280x1024 secondary screen.
I found I was logged out after a period of inactivity, which turned out
to be when the screensaver kicked in. I could stop this occurring by
either disabling the second screen in "Screens and Graphics" or by
choosing a non-OpenGL screensaver like Braid. After each crash,
Xorg.0.log.old contained this at the end:
SetClientVersion: 0 9
SetGrabKeysState - disabled

Further investigation showed that OpenGL applications are not rendered
on the second monitor, and I imagine this will be the source of the
screensaver crash. I run glxgears and see the gears on the main screens,
but when I drag it onto the secondary screen the window is black - the
gears are not rendered.
Finally, here is my xorg.conf:
# xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

# Edit this file with caution, and see the xorg.conf manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
