I've had a resolution problem similar to this before, but was able to solve it on my laptop..
My maximum allowed resolution in KDE is currently 1280x1024. I've added 1600x1200 to the xorg.conf file to make it look like the following:
Code:
# "1024x768" is also a conservative usable default resolution. If you
# have a better monitor, feel free to try resolutions such as
# "1152x864", "1280x1024", "1600x1200", and "1800x1400" (or whatever your
# card/monitor can produce)
Subsection "Display"
Depth 8
Modes "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
EndSubsection

EndSubsection
I've also modified the hsync max (which solved the problem on my laptop) to support the higher resolutions. However, this time, it only allowed me to select 1280x1024 as the highest resolution. I checked the /var/log/Xorg.0.log file and saw that there were no 1600x1200 modes available. The highest mode available showing in the log file is:
Code:

This is where my laptop and desktop differ. The laptop has entries for a 1600x1200 mode. What file, and what modifications need to be done to add this 1600x1200 mode?
Thanks in advance.
