 You need typical keyboard and mouse configuration sections, too.
+===== xserver 1.8+ and input devices + udev =====
+Hal is no longer used. See [[https://wiki.ubuntu.com/X/Config/Input#Input|https://wiki.ubuntu.com/X/Config/Input#Input]]

 ===== synaptics and mouse tapping =====
+**WARNING**: do not add any kind of synaptics entries to xorg.conf. If you do, xorg will see two of them -- the manually-added one and the automatically-detected one (type //xinput list// to see a list of all detected input devices) and all of the configuration options listed below will get applied to the **wrong** one. In other words, as long as there's a synaptics entry in xorg.conf, you won't have any way to change the drivers configs.
 Xorg v7.4 does not enable tapping by default. To enable add to 11-x11-synaptics.fdi:

+===== 100% CPU usage when using xdm (kdm, gdm) and SysVinit (not upstart-SysVinit) =====
+The problem is that when xdm runs with recent X server then tty0 (as it's first free tty) is taken by xserver. Then when [[:SysVinit|SysVinit]] tries to run mingetty also on tty0. This ends with mingetty fighiting with X server for tty0.
+upstart-Sysvinit is not affected as it starts mingetty before xdm runs, so xdm choses different, first free ttyX.
+Solution: change xdm to use fixed tty that's not used in inittab for mingettys (like tty9).
+===== xorg-driver-video-intel >= 2.9.99.0 requires KMS =====
+Latest Intel xorg drivers require KMS (kernel mode setting) to be active. Run kernel >= 2.6.31 and set in /etc/sysconfig/geninitrd:
+<file>PREMODS="intel-agp i915"
+</file>
+and regenerate geninitrd.
+Alternatively run:
+<file>modprobe i915
+</file>
+===== XDMCP =====
+If you want to create cross computer X sessions using XDMCP please enable it *dm (kdm, gdm) on machine you wish to connect to.
+Now you can run:
+<file> X -query xdmcp.enabled.server
+</file>
+or just  X or local kdm and select network log in instead of local log in.
+==== Source IP# number problem on client machine ====
+Rules which X selects interface on which it binds for X sessions are not clear for some people. If you spot problem :
+<file>XDMCP fatal error: Session failed Session <some_number> failed for display my.adress.not.acessible.to.server:0: cannot open display
+</file>
+Try if forcing connection source ip adress helps:
+<file> X -query xdmcp.enabled.server  -from  my.adress.acessible.to.server
+</file>
