Fedora 18 Terminal is automatically closed

edit

if your ctrl+alt+F2 doesn't work or hands you probably have video driver problem with the terminal windows, but this is not the question to resolve right now, you can boot your laptop with a dvd an follow this step :

select troubleshooting 
rescue a fedora system 
continue 
ok
ok 
start shell

now you are in the terminal, now you have to access your system, type this in the terminal :

chroot /mnt/sysimage/

now you are in your system.

If you would like to do a complete reset of the Gnome Terminal settings, the directory that store this information is ~/.gconf/apps/gnome-terminal (in a normal situation you can delete with ctrl+alt+F2 and the back to GUI with ctrl+alt+F1).

Then delete it:

rm -rf /home/youruserhere/.gconf/apps/gnome-terminal

and reboot you laptop as normal.

hth,
