That's very odd. I'm using the nouveau driver, and 2560x1600 works
for me. /var/log/Xorg.0.log should provide some clues.

Have you got something in /etc/X11/xorg.conf or /etc/X11/xorg.conf.d ?

If the monitor doesn't return its capabilities via EDID reliably, the
system will default to 1024x768. Try "xrandr" and see what you get.
Here's a sample from my system:

[root@prophead tmp]# xrandr
Screen 0: minimum 320 x 200, current 1920 x 1080, maximum 8192 x 8192
DVI-I-1 connected 1920x1080+0+0 (normal left inverted right x axis y
axis) 598mm x 336mm

1920x1080 60.0*+ 60.0
1600x1200 60.0
1680x1050 60.0
1280x1024 75.0 60.0
1440x900 59.9
1280x960 60.0
1152x864 75.0
1024x768 75.1 70.1 60.0
832x624 74.6
800x600 72.2 75.0 60.3 56.2
640x480 72.8 75.0 66.7 60.0
720x400 70.1
DVI-I-2 disconnected (normal left inverted right x axis y axis)

If you don't see your 1920x1080 in there, then you can forcing it by
trying "xrandr --mode 1920x1080" to see if that'll bite. If it does,
then you can add appropriate lines to your xorg.conf file.

No, except what was previously installed.

There should not be one. That's ancient history. Everything
should be autodetected. The interesting question in your case
is why the monitor isn't being autodetected. Is it some ancient
monitor with no EDID? Or a faulty cable?

My problem now is to make it starts with the right resolution.
I tried to edit /etc/gdm/Init/Default

and to create a /etc/X11/xorg.conf

but it does not help.

tried what yoou suggest. Although man xrandr says there iws a --mode
option when I run xrandr --mode I get a response that the option does
not exist. Why is that?

Ah, yes. Try "xrandr --fb 1920x1080". I think "--mode" was for a
previous version of xrandr. Did just "xrandr" show the ability to do
1920x1080? I'm trying to see if your monitor or cable just isn't
reporting the EDID info properly.
