Sometimes xorg.conf is missing for some reason. Xorg will then probe your hardware on every startup. Though this works fine in most cases, some settings remain inaccessible. To create a starting point for customization, do the following: If xorg.conf is missing for some reason, Xorg will probe your hardware on every startup. Though this works fine in most cases, some settings remain inaccessible. To create a starting point for customization, do the following:

Xorg is a the default X-Window server since Debian 4.0 (etch). It replaces XFree86. It is maintained in Debian by the XStrikeForce.

Current Status

  • Current testing release is roughly Xorg 7.2. In unstable it is roughly Xorg 7.3. Please see Xorg69To7 if you are upgrading from XFree86 or a 6.x version of Xorg.

  • There is currently no experimental release although individual driver updates are available.

Configure X

To reconfigure keyboard settings, run as root in a terminal: 

dpkg-reconfigure xserver-xorg

This command formally included steps to configure video settings but as of Winter 2008 in Testing, these screens no longer appear. This is reportedly because auto-detection of video settings works in most cases so a wizard is unneeded. Any further adjustment to video settings must be done by editing /etc/X11/xorg.conf directly.

Edit xorg.conf

Some settings are only accessible through editing xorg.conf by hand.

How can I edit my xorg config file?

Open a terminal (or console) as root, then run : 

editor /etc/X11/xorg.conf

What if I do not have an xorg config file?

If xorg.conf is missing for some reason, Xorg will probe your hardware on every startup. Though this works fine in most cases, some settings remain inaccessible. To create a starting point for customization, do the following:

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

or as root run 

invoke-rc.d gdm

(see gdm manpage).

KDE user should use kdm. Others might use xdm.
