Hello, are there any Gnome/GTK wizards on this list? Something went horribly wrong this morning with the new install of FC3 on my son's computer: nothing that uses GTK will work. On boot, or when exiting a session, this message appears on what should be the login screen: "The greeter program appears to be crashing. I will attempt to use a different one." When trying to log in using GNOME the following error appears: "Your session only lasted less than 10 seconds. If you have not logged out yourself, this could mean that there is some installation problem or you are out of disk space...." There is a checkbox that allows viewing of ~/.xsession-errors -- checking it reveals nothing interesting, only this: [first line:] /etc/X11/gdm/PreSession/Default: registering your session with wtmp and utmp [second line:] /etc/X11/gdm/PreSession/Default: running: /usr/bin/X11/sessreg -a -w /var/log/wtmp -u /var/run/utmp -x "/var/gdm/:0.Xservers" -h "" -l ":0" "root" [third line:] Agent pid 9172 [last line:] SESSION_MANAGER=local/hostname:/tmp.ICE-unix/9684 This happens no matter who tries to log in to a GNOME session (even root). We can log in to KDE sessions but nothing that relies on GTK (such as system-config-packages, which would allow us to remove and reinstall Gnome) works. This is a fresh stock install that was fully updated last night. It's probably not a FC3-specific bug because my install is working perfectly on similar hardware. I presume there is a file somewhere that got corrupted, but running 'rpm -Va' produces a very long listing of dependencies that changed when prelink was run, and there's a lot to comb through there. Is there anyone reading this who can tell me where to look next? Thanks, Ken
