Ubuntu 9.10 Karmic Koala - VNC resolution limited without monitor

Update 04/23/2010 - I’m not finding a solution to this issue. Sorry. I’ve lost interest.

I recently setup Ubuntu 9.10 on a desktop system, so I could use it as a file server. I’m was able to enable the remote desktop feature for it, which is basically a VNC server.

The issue is that once I disconnected a monitor from the computer and set it up next to my router (plugged directly in), and restarted it, VNC would only work with a maximum resolution of 640x480.

In a forum someone pointed out that this configuration added to /etc/X11/xorg.conf would save the day:

Section "Device"
  Identifier "VNC Device"
  Driver "vesa"
EndSection

Section "Screen"
  Identifier "VNC Screen"
  Device "VNC Device"
  Monitor "VNC Monitor"
  SubSection "Display"
  Modes "1024x768"
  EndSubSection
EndSection

Section "Monitor"
  Identifier "VNC Monitor"
  HorizSync 30-70
  VertRefresh 50-75
EndSection

I just restarted after my ‘sudo service gdm restart’ command didn’t seem to work. I think this might have something to do with a special Nvidia driver I’m using. Hm…

And I thought this most recent article was giving me the holy grail.

Eh. I’m going to bed now. It’s 3:29 AM. I’ll slay this dragon later perhaps.
