gnome doesn't start from gui login
I installed redhat 8.0 several days ago. I found only the most basic window manager "twm" start up (instead of the default -- gnome) when I login from the gui login. However, if I change the setting of /etc/inittab, start the machine on text mode, and use startx command to start the x-windows and gnome, it works just FINE (i.e., Gnome starts successfully). Does this means that I need to configure some files related to gui login so the gnome (instead of twm) can start? If so, which file should I try? Thanks!
