Hi titan,
Thanks for the tips. It turns out I did not have a driver for my graphics card installed. After installing the ATI FirePro v4900 driver, I was able to get higher resolution. It seem to default at 1600×1200, which appears to be the highest mode indicated by the xrandr command:
# xrandr -q
Screen 0: minimum 320 x 200, current 1600 x 1200, maximum 1600 x 1600

However, my monitor attached to the machine I am running the NoMachine client from is capable of much higher resolution – 1920×1080. I have tried using the cvt command to create a Modeline for 1920×1080 and adding to my xorg.conf, but it seems to be ignored and my NoMachine sessions are stuck at 1600×1200.
Do you have any advice on how I can get 1920×1080? I have also tried capturing the EDID info for my monitor to a file and using the CustomEDID option. That didn’t work either.
Thanks,
Dallas
