Description of problem: vncserver / Xvnc ignores -geometry and -screen scrn ... always sets 1920x1200, what is furthermore not the documented default (1024x768) Version-Release number of selected component (if applicable): tigervnc-server-1.1.0-5.fc17.x86_64 How reproducible: start a vncserver, connect and look and run xdpyinfo Steps to Reproduce: 1. prompt# vncserver -geometry 1000x800 (or whatever) ( 2. prompt# vncviewer :1 Actual results: Display size is always 1920x1200 Expected results: Display size is 1000x800 Additional info: -screen scrn ... does not work either.
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 request.
