Another nVidia Problem

[David]

I have an nVidia GT 220 with 1MB of RAM on an AMD Athlon 7750 dual
core processor with 4 GB RAM running Open SuSE 11.3 and KDE.

I recently changed my KVM switch to one which allows the use of DVI-D
with my LG W2343 monitor.

The windows machine accepted the change gracefully but the Linux
machine does not want to set the resolution to the native 1920 x 1080.

I have recompiled the nVidia module with the recommended
NVIDIA-Linux-x86-304.43.run downloaded from the nVidia site.

Can anyone help me with the appropriate modeline to put in the
configuration files, please?

Assuming you are running Xorg as your X11 server, then if you do not have
an xorg.conf to specify suitable resolutions for your monitor, then the
Xorg server will try to query the monitor to get the resolutions that
it will support.

Look for something like "Printing probed modes for output VGA-0"
in /var/log/Xorg.0.log

If the KVM switch is preventing the Xorg server from getting the
information from the monitor, then you will need to manually
specify your supported and preferred native resolution of 1920x1080
in an xorg.conf file.

In the screen section

SubSection "Display"
Depth 24
Modes "1920x1080"
Viewport 0 0
EndSubSection

Thank you, this gave me the clue by four I needed. I had the following
line in my xorg.conf file

Option "UseEDID" "False"

I changed that to "true" and everything worked as desired.

Was it set to "False" before you started using the KVM?
