This is a problem I had with PCLinuxOS 2007 while using my Dell 2407WFPb.
With onboard video ∞
(2007-06-24 or earlier)
PCLinuxOS .93 works fine at 1920x1200. However the PCLinuxOS 2007 test releases and final version were displaying some kind of 1600x1200 resolution.
This is not an issue of 'fill' or 'aspect' monitor settings.

s3 unichrome Pro VGA Adapter
When I configure it, it shows the proper monitor.
It also shows my expected resolution - except that it's obviously lying. I change the resolution right down and test it, and it shows the same exact resolution and asks for my confirmation. Strange.
What I did to solve it was hack
Remove all excess options, including different resolution options and such.
Change an existing Monitor setting thusly:
ModeLine "1920x1200_60" 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -HSync +Vsync
ModeLine "1920x1200" 193.16 1920 2048 2256 2592 1200 1201 1204 1242 -HSync +Vsync
With a GeForce 5200 ∞
- Fix the BIOS so that it's defaulting to use an AGP video card and not onboard video.
Install the correct drivers:
apt-get install dkms-nvidia_96xx
I then get the below message. I did exit the shell I had open while I had the 10 second grace period.
My next steps ∞
Full reboots and reinstalls of this software did not change anything. There is no 'nvidia' driver.
I even installed this:
apt-get install nvidia_96xx
which didn't seem to have been installed before. Then when I reinstalled the other drivers like so:
apt-get reinstall dkms-nvidia_96xx
This seems to have reinstalled both
nvidia_96xx .. strange. Something is broken with the packaging.
other notes ∞
cp /etc/X11/xorg.conf /etc/X11/xorg.conf.orig
nvidia-xconfig -composite; nvidia-xconfig --allow-glx-with-composite
nvidia-xconfig --render-accel; nvidia-xconfig -add-argb-glx-visuals
Open your xorg.conf file and make sure the
Section "Module" contains the line
Load "glx" and that this section exists:
Option "Composite" "Enable"
