 Posted: Fri Sep 28, 2007 9:34 pm Post subject: Xinerama with different resolutions |
 |
|
Hello Forum,
I'm trying and googeling now for about a year about the same Problem and didn't find a solution yet.
I have a Laptop with a screen which has 1024x768 resolution. At work I connect it to a second Monitor which has 1280x1024px. I use them both with Xinerama. I guess that's the only solution for the i810 onboard graphics Chip.
The Problem I have with that is that both monitors must have the same resolution and because Laptop has a lower, the other Monitor (a 19" TFT) must also have this low resolution and the picture looks quite ugly because of that.
You can already guess  My Question: Is it possible to use two screens with different Resolution with Xinerama and how?
For information I'll post my xorg.conf at the end of this posting.
Thanks and best regards,
Joe

I use Nvidia's Twinview in conjuction with Xinerama, and there's a property of the Screen section in my xorg.conf called meta modes which allows me to do just this.
| Code: | Section "Screen"
Identifier "Screen-Auto"
Device "LCD"
Monitor "LCD-Panel"
DefaultDepth 24
Option "Twinview" "1"
Option "metamodes" "CRT: 800x600 +1280+0, DFP: 1280x800 +0+0; CRT: 640x480 +1280+0, DFP: 1024x768 +0+0; DFP: 800x600 +0+0"
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x800" "1024x768" "800x600"
EndSubSection
EndSection
|
Not sure if metamodes are a twinview or a xinerama thing though, I'd have to look it up, and it's nearly 3am right now...

I tried the meta modes but it hadn't any effect. I suppose it's twinview specific...
I tried to set the TFT screen on 800x600 and the laptop screen on 1024x768 to see if it's in general possible to have two screens with different resolution running with Xinerama, and it worked.
So there must be a way to have TFT with 1280x1024 and Laptop with 1024x768... Something must be wrong with my configuration...
Any more hints?
Thanks!
