I've been using a VNC server for quite a few years and have run into a problem with setting screen geometry. The server and config were working great up until Fedora 16 and 17. I thought it might be something to do with systemd, but the same problem occurs when I launch vncserver from the command line. Here is what I use.
Code:
vncserver :2 -geometry 1366x768 -depth 24
When I connect, rather than getting 1366x768 it comes up 1920x1200. Now where in the world is it getting that from? I could understand if it were the default of 1024x768, but this value is coming from out of the blue.
My log file is below. There are a lot of warnings and a few other oddities. You can see the width and height settings where it starts talking about Xinerama. I also don't understand why Xinerama and DPMS are even coming into play. I'm guessing it might be something that Gnome is doing or maybe even X. Anyone else run into this or have an idea what could be causing the trouble?
