SamSung 213T LCD DVI with X under Fedora ??

[Ernest L. Williams Jr.]

Hi,

I just got a brand new SamSung 213T LCD monitor and a Matrox G450 MMS
graphics card and it doesn't want to play on the DVI interface.  When I
used the analog input all is well at 1600x1200.  What a beautiful
monitor.

In order to get the DVI going is there a special configuration in the
xorg.conf?


Any ideas?



Thanks,
Ernesto

What kind of problem are you having? Errors or warning in
your /var/log/Xorg.0.log when you have it hooked up DVI?

Wait until you have had it a while and get used to it. :-) I've I had my
213T(silver) since April connected to the DVI output on an ATI Radeon
9800 Pro. The picture is fantastic.

I the only thing I changed in my xorg.conf was to set the refresh rates.
Note, the DVI rates are different from the analog rates. These should be
auto detected by the video driver anyway.

I have tried it so many
times the history only shows success with the
analog.
I will switch back to DVI and try again.

When I had the DVI cable connected, the monitor kept switching between
analog and digital.

Do you have a matrox G450 as well?

Maybe, I need to add the following sort of lines to the device section
of my xorg.conf file:
=============================================================================
Option      "DigitalScreen1" "on"
Option      "DigitalScreen2" "on"
===============================================================================

Does linux support for ATI Radeon is good?

Okay, I got it now had to add the following:

To add DVI support, add the following line to the device section:
Option "DigitalScreen" "yes"
