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
DFP1 disconnected (normal left inverted right x axis y axis)
DFP2 disconnected (normal left inverted right x axis y axis)
DFP3 disconnected (normal left inverted right x axis y axis)
DFP4 disconnected (normal left inverted right x axis y axis)
DFP5 disconnected (normal left inverted right x axis y axis)
DFP6 disconnected (normal left inverted right x axis y axis)
DFP7 disconnected (normal left inverted right x axis y axis)
DFP8 disconnected (normal left inverted right x axis y axis)
DFP9 disconnected (normal left inverted right x axis y axis)
CRT1 connected 1600×1200+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
1600×1200      60.0*+
1400×1050      60.0
1600×900       60.0
1280×1024      60.0
1440×900       59.9
1280×960       60.0
1366×768       59.8
1360×768       60.0
1280×800       59.8
1152×864       60.0
1280×768       59.9
1280×720       60.0
1024×768       60.0
800×600        60.3
720×480        60.0
640×480        59.9

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
