Question Changing resolution in Red Hat Gnome using UltraVNC

Hi all,

I'm accessing a Red Hat Linux 5.5 machine with Gnome 2.16 and UltraVNC. I've started "vncserver" and am accessing my Linux desktop fine from my Windows machine. However, I can't change the resolution as I'm told:

The X Server does not support the XRandR extension. Runtime resolution changes to the display size are not available.

Does anyone know how I can fix this?

You normally set the geometry with the command-line option (--geometry widthxheight), and do not plan on trying to resize it from the viewer.

If you start the server WITHOUT that option, you MAY be able to select the geometry from the viewer, but you should set it in the options prior to connecting to the server.

Dynamic desktop geometry changes took a long time to provide for local desktops, and does not always work well even now. Dynamic remote desktop geometry is another interesting problem with many variables that cannot be simplified. IT can be solved for limited cases, and has: perhaps not for YOUR case.
