VNCViewer screen resolution

I didn’t have much to report with my upgrade fom 6.06 – 6.10 – 7.04 as everything worked ok. I have just inherited a new PC and so I have installed Ubuntu 7.04 from scratch, no problems so far. I decided to use my old PC as a server for web, mail and ftp and will be reporting on my experience with this project as I go along. In order to access the server I have installed VNCviewer and here was my first problem. The server had a maximum resolution of 800×600 and whatever I did by adding to the xorg.conf file I couldn’t improve it. I finally figured it out that because there was no monitor for x to autodetect it stuck to a default resolution. To stop the autodetect you have to enter a horizontal and vertical refresh range into the monitor section of /etx/X11/xorg.conf. Like this:
Section "Monitor"
Identifier "Generic Monitor"
Option "DPMS"
HorizSync 31-95
VertRefresh 50-60
EndSection

Then you can select any resolution you want.
