ways to configure Linux X display driver

continuing my popular howto easily configure x display, here are other ways to configure X display driver in Linux.

first, we should backup the original xorg.conf, just in case...
cp /etc/X11/xorg.conf xorg.conf.backup1
and when we need to restore:
sudo cp xorg.conf.backup1 /etc/X11/xorg.conf
you might also want to backup xorg.conf from each step result and then choose the one that satisfy you most.

so here's many ways how to configure your X display driver:
  • sudo rm /etc/X11/xorg.conf # just remove the xorg.conf. usualy, X will try to configure itself.
  • if you have gdm installed, kill it with Ctrl-Alt-Backspace until it gives safe mode. or intentionally breaks xorg.conf with wrong entries. 
  • sudo X -configure && sudo cp xorg.conf.new /etc/X11/xorg.conf
  • sudo dpkg-reconfigure -phigh xserver-xorg
  • sudo displayconfig-gtk
  • try paste xorg.conf from failsafe / default xorg.conf
  • Fix Video Resolution Howto on ubuntu
as always, most stuffs should also works with debian and derivatives.
