[Bug 60438] Re: Changing Screen Saver locks up entire system

[Tormod Volden]

Does for instance "Deco" also crash ? (One surely without 3D graphics).
Can you please look through /var/log/syslog to see if there were any
error messages? Please attach /var/log/Xorg.0.log.old just after
rebooting from the crash.
