I just finished a netinst of Debian Squeeze on a clean (repartitioned and reformatted) old dell desktop.
When first booting up, it attempts to start GNOME but fails with the error:
"Failed to start the X server (your graphical interface). It is likely that it is not set up correctly. Would you like to view the X server output to diagnose the problem?"
If I say yes, what it shows me seems to be an abbreviated version of Xorg.0.log. (I have attached the complete log.) This shows the following errors
(EE) open /dev/fb0: No such file or directory
(EE) ioctl EVIOCGNAME failed: Inappropriate ioctl for device
(EE) PreInit returned NULL for ""ImPS/2 Generic Wheel Mouse""
When I continue it says "The X server is now disabled. Restart GDM when it is configured correctly."
hitting 'ok' takes me back to a terminal screen login prompt.
NOW I can log in and issue 'startx' and GNOME WILL LOAD, (eventually) but runs so slow I can't actually use it for anything.
'top' shows the cpu is being consumed by Nautilus (around 50%) and Xorg (around 30%.)
<ctrl>+<alt>+<F1> kills GNOME and returns me to the terminal where it displays the last few entries to Xorg.0.log, but it never gives me a prompt so I'm just stuck there. I have to SSH in from another machine and kill the startx process before I can get a prompt on the server.
Any advice on troubleshooting this would be greatly appreciated. Logs attached.
e: And fwiw, this link in the post-install configuration sticky is dead.
