I have two monitors that i would like to have run at 1280x1024. I have a geforce ti4200 card. My current XFConfig makes the monitor on the right at a lower res than the monitor on the left and also, they are messed up, the image starts on the left most side of the monitor on the left but goes to the left and continues on the right most part of the the monitor on the right. Its basically like i need to pick up both moinitor and swap there position. here is my XFConfig file:

Code: Select all

# Server flags section.

    HorizSync   30-94


#    HorizSync  30-64         # multisync

I'm not sure why the second monitor is at a different resolution. I would guess it is something with your twinview setup, I've got two cards a geforce2 in the agp and a crappy s3 in a pci so I'm not familiar with the twinview options/setup. It could also be that the second monitor isn't configured propery and X won't let it run at that high of a resolution.

For setting up where the monitors are though try something like this instead the RightOf part

Code: Select all

Section "ServerLayout"
    Identifier "Xinerama" # whatever you want to call it
    Screen "Screen 0" 0 0
    Screen "Screen 1" 1280 0
    #Upper left corner is 1280 right and 0 down
    option "xinerama"
    InputDevice "Mouse1" "CorePointer"
    InputDevice "Keyboard1" "CoreKeyboard"
EndSection

don't mean to hijack the thread, but does anyone know anything about keeping an S3 card from interferring with sound when there is movement on the screen?

This is some relevant bits from my setup with a ti4200 (both monitors are the same rez). You should be able to adjust the twinvieworientation and metamodes settings to get your monitors in the right area and configured with the right modes. I found good information in the nvidia-glx (or -kernel) does in /usr/share/doc/nvidia-{glx,kernel}/*

HTH. Email me at alan - at - ufies dawt org and I can pass on my complete XF86Config file.
