Log out of X, log back in: no change.
Log out of X, zap X (/etc/init.d/gdm restarts it), log in: no change.
Log out of X, /etc/init.d/gdm stop, reload driver, /etc/init.d/gdm start,
log in:
root@pc:~# runlevel
unknown
That can't be good. Lemme reboot.
...
eben@pc:~$ time xterm -e bash -c exit
real 0m0.019s
user 0m0.013s
sys 0m0.005s
