Debian Lenny.

Have not used Linux (Debian) for a while. Today, my old computer for my son showed some problem with X windows. I could not start the X server. Tried to reconfigure the Xorg. The Wiki from Debian is very helpful. Followings are the steps I followed.

Switch to a console as root (not a terminal emulator in X), then run:

/etc/init.d/kdm stop
/etc/init.d/gdm stop
/etc/init.d/xdm stop
cd /etc/X11/
Xorg -configure

Alternatively, reboot the machine in single user mode, then run:

cd /etc/X11/
Xorg -configure

Follow the on-screen instructions. This should give you something to work with.

Run X

After installation run:

startx
