Default Resolution independance and dual monitor setup possible?

When I enambel twinveiw on my SUSE 9.0 system I get one resolution for moth monitors...

One of my monitors is smaller then the other and the desktop gets bigger than the actual visible area on the screen... is there a way to get the configuration to give the second monitor a more accurate resolution?

thx in advance for your help!

Default Re: Resolution independance and dual monitor setup possible?

This is a "feature" of X and it can't be disabled. In case of the type of twinview you are using X thinks it has lets say a desktop of 2 * 1024x768 = 2048x768. Although you might only want 800x600 of the second screen. The rest of the screen becomes "virtual" (you nee need to scroll to reach it).
Assuming you use that "1024x768, 800x600" you can access the unused space by using "1024x768, 800x600@1024x768" but this is I think not what you want.

The only way to get two different resolutions on both screens is to use the "seperate X desktop" approach as described in appendix R of the driver readme. Then both screens will be seperate but you can't move screens over (can be done if you enable xinerama but then the virtual problem is back again too). Note that when using seperate desktops the desktops are really seperate so you need to load gnome or kde on it.

What about using a second video card for the second display? (like a FX5200 pci)

Using this seperate desktop approach, the system behaves like there are two videocards both with a different desktop.

If I do use this "1024x768, 800x600@1024x768" will I be able to see the entire screen on the second monitor? And if it does will it screw with the the first monitor?

Also, It seems I'm unable to play quake3 at full screen... is there a way to get around that and have the game play on the main 1024X768 monitor?

Thx for your help!

I never tried it but:
Option "MetaModes" "string"
This option describes the combination of modes to use
on each monitor when using TwinView.

i can recommend: http://www.sorgonet.com/linux/nv-online/

I tried that script using the following inputs:

Driver "nvidia"
Option "NvAGP" "3"
Option "DigitalVibrance" "0"
Option "TransparentIndex" "0"
Option "CursorShadowAlpha" "64"
Option "CursorShadowXOffse" "4"
Option "CursorShadowYOffset" "2"
Option "Twinview" "TRUE"
Option "TwinViewOrientation" "RightOf"
Option "SecondMonitorHorizSync" "0"
Option "SecondMonitorVertRefresh" "0"
Option "MetaModes" "1024x768 , 1820x1024"
Option "ConnectedMonitor" "CRT , CRT"


I put them here: (where the "#" are with the exception of the "driver" line)

Section "Device"
BoardName "GeForce FX5600"
BusID "1:5:0"
Driver "nvidia"
Identifier "Device[0]"
Screen 0
######################
VendorName "NVidia"
EndSection

This failed and I had to go to the backup file..... My left monitor is a TFT flat screen does this matter? I also tried just using one line: Option "Twinview" "TRUE" This did not work either... I used XF86Config as the script build option also... and I used "1280x1024, 1280x1024" in metemodes to trie balance and then I also took everything out but the twinveiw option.... it always went to the same screen... never went twinview...

Anybody got any suggestions? Thanks!
