Because I want to fill a bug report, I need to start my X server with some log options. Therefore, I did on my Jaunty 9.04 installation in tty1 (ctrl-alt-f1):
sudo /etc/init.d/gdm stop
startx -- -logverbose 6
This results in stopping the current X server and it starts a new one. However, the new one only displays a black screen and I have to switch back to the terminal and type
sudo /etc/init.d/gdm start
to get a working X again.
I'm running the 185.18.14 driver on a Geforce 7300. This behavior also occured with the previous installed 185.18.10.
Does someone know a solution to my problem?
