==== xorg.conf ====

Grunde til at skulle kunne redigere xorg.conf (fra mailinglist)

 1) have a tablet work;

 2) have a blacklisted Synaptics touchpad work;

 3) have some AGP graphics cards run in 4x mode instead of the default 1x mode;

 4) enable some extensions that were not enabled by default, like DRI2, EXA, XRANDR, or disable some that did not  oexist peacefully with some other (IIRC I once had to disable COMPOSITE in order to activate some other feature);

 5) have a custom ServerLayout section;

 6) have a working ModeLine for a mode that was not automatically detected by Xorg;

 7) enable the intel drivers' MPEG2 MC support that was disabled by default on the gpu used.
