I just installed Ubuntu 9.10 yesterday. The only problem is that 9.10 fail to detect my dual monitors; therefore, the resolution of my two monitors were set to 1024*768 by default. I spent one day to complete solve this problem. My graphic card is a ATI one. You may skip this page if your graphic card is not ATI. Here’s how.
1. Download ATI driver from Ubuntu Hardware Driver setting. Run the following command.
sudo amdcccle
2. Set correct resolution for both screen. (1280*800 and 1600*1200 for me). It was weird at the beginning, because ATI control center only allowed me to set my second monitor to 1280*800. I solved this problem by unplugging the monitor and reboot my box(Maybe).
3. (Optional) Revert the screen location. My second monitor is on my right hand side. I tried to set the screen position in AIT control center. But the control center always crash after I apply the change. I have no option but changing xorg.conf manually.
Section “Monitor”
Identifier “0-LCD”
Option “VendorName” “ATI Proprietary Driver”
Option “ModelName” “Generic Autodetecting Monitor”
Option “DPMS” “true”
Option “PreferredMode” “1280×800″
Option “TargetRefresh” “60″
Option “Position” “0 0″
Option “Rotate” “normal”
Option “Disable” “false”
EndSection
Section “Monitor”
Identifier “0-CRT1″
Option “VendorName” “ATI Proprietary Driver”
Option “ModelName” “Generic Autodetecting Monitor”
Option “DPMS” “true”
Option “PreferredMode” “1600×1200″
Option “TargetRefresh” “60″
Option “Position” “1280 0″
Option “Rotate” “normal”
Option “Disable” “false”
EndSection
The position option indicates the start point of a screen.
All Done!

First, backup your /etc/X11/xorg.conf
Then, sudo dpkg-reconfigure xserver-xorg This command reconfigures xorg.
Then, reboot the system. Your ubuntu should be able to recognize your monitor but not in right resolution
in system->Administration->Hardware Device. Select ati driver. Reboot again.
Make sure in your xorg.conf contains the following info
Section “Screen”
#add these three lines
SubSection “Display”
Virtual 2640 1568 #2640=1200+1340 1568=800+768 which is my two monitors resolution
EndSubSection
#———————————
Identifier “Default Screen”
Device “Configured Video Device”
Monitor “Configured Monitor”
DefaultDepth 24
EndSection
Reboot again. I spent 2+ hours to make everything right. Here is my xorg.conf file. I use default ubuntu ati driver. It takes time, be patient
