Ok. Sorry Guys to make you wait so long but I want to make sure that this configuration is WORK.

The point to to this is to expand your desktop to an another LCD or CRT Monitors. For me, I call Dual Monitor Setting.

Note: This method support for ATI users with Ubuntu Linux 8.04 and using aticonfig command to do this

HOW TO:

  1.  Back up xorg.conf by

    • sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf.backup

  2. Config X Windows use fglrx Drivers

    • sudo aticonfig --initial --overlay-type=Xv

  3. Config Dual Monitor Setting
    1. This sections will describe which options that you can enter is
      • --desktop-setup=horizontal,reverse <= flips your screens.
      • --desktop-setup=vertical <=places your monitors in a up-down orientation.
      • --desktop-setup=vertical,reverse <=flips your screens.
      • --desktop-setup=clone
      • --desktop-setup=single
        Note: These options is almost self-describe such as desktop-setup=clone // that is make the monitor show the same display.
      • --add-pairmode=Width0xHeight0+Width1xHeight1 // this command prevents tearing during 3D rendering. Because this command tells X what the resolutions are for Monitor1+Monitor2. 
      • sudo aticonfig --desktop-setup=horizontal --sync-vsync=on --add-pairmode=Width0xHeight0+Width1xHeight1

  4. Now Check The Monitors we can detect:

    • sudo aticonfig --enable-monitor=STRING,STRING

      • The value STRING can be one of these
        1. none
        2. crt1
        3. crt2
        4. lvds
        5. tv
        6. tmds1
        7. tmds2
  5. If the enable-monitor commands doesn't work for you, we need to use this command:
    • sudo aticonfig --force-monitor=STRING,STRING
  6. Restart X by (Ctrl+Alt+Backspace) or Reboot the System
