11.4 jumps to log in screen after starting an application

I just installed the brand new 11.4 on an old Dell Optiplex GX280 box.
After the proxy been set, I tried to open firefox but then, all jumps back to the log in screen. The same happens when I try to open pgadmin.
After logging in, all the open windows are gone.

This doesn’t happen in failsafe mode.
Any help?

begin reading from the top (so you get the context) this page,
http://en.opensuse.org/SDB:Configuring_graphics_cards and when you get
to it, try “The 1st thing to try is to boot from grub with boot code:

i suspect that will cause the jumping back to stop…if it does then
there is a second thing to try, and so on . . .
