Comment 1 Albert Flügel 2012-08-27 10:25:41 EDT
This was a misunderstanding, sorry. I found now, that GNOME3 by default
uses the RANDR extension of an Xserver to change the resolution and
there seems no way to keep GNOME3 from doing this. So starting vncserver /
Xvnc with option -extension RANDR prevents the resizing.

When i connected the vncviewer, the resize was already done and i
did not try with any other window manager. So i did not see, that
initially Xvnc sets the correct resolution and later changes due to
