 |
|
Hi, running the ATI proprietary drivers, and the latest Gnome releases as well as Xorg, I have both monitors up and running in a Big Desktop scenario but Monitor 2 is always at the "incorrect" resolution. Now I know that **ideally** you are supposed to have 2 identical monitors when you run dual heads in Linux since the driver situation is very primitive.
Unfortunately, what I have here is a 1400x900 widescreen and a 1280x1024 "square" flat panel.
The 1400x900 is monitor 1 and it's running perfectly.
The 1280x1024 insists on displaying 1280x720 and it's making the screen look like hell since it's not a native resolution not to mention the messed-up aspect ratio.
To get this to work, I stacked the "big desktop" vertically, with Moni 2 below moni 1.
So where is a good starting place for me to troubleshoot this? Once I get a clue or two, I can probably figure it out. For the record, this ATI 9800 can do both monitors in their correct native modes in Win XP so it's not the card.

My magic 8-ball is saying "Reply hazy. Please post your xorg.conf file."

I don't know much about this "PairMode" option, but it would seem to me that the first monitor resolution should be listed first, and it's listed second.
Could that be causeing your craziness?

| I reversed the PairMode option and nothing changed, but I did change Monitor 1 to Monitor 0 and this made the dominant mode 1280x1024 ... the Square monitor was now "correct" and the widescreen was now in the wrong modes; the reverse of the original situation. |

Isn't there an option to set up the specs of the second monitor in the drivers section?
