1600x1200 though DVI in Ubuntu 9.1

[oversky]

I connect Dell 2007FP(1600x1200) to my T42(ATI mobile radeon 9000) through port replicator II DVI port.
I have no problem in windows xp sp2, but the monitor turns into sleep mode in Ubuntu 9.1
Can anyone share your xorg.conf that works? Thanks.

Moved to the Linux forum for more responses.

Check your /var/log/Xorg.0.log

The file is 234 KB. Can you tell me what to check?
I uploaded the file to dropbox.

DVI is being set up correctly, it seems. Did you enable the output? Either gnome-display-properties or xrandr --output DVI-0 --auto. Do you see other resolutions?

Finally, I made it work. Following is my xorg.conf. I got the correct modeline from power strip. See following link for detail.
