Dual Head Monitor in Gutsy

ตอนแรกนึกว่าจะใช้ไม่ได้แล้น :P

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
