Description Sebastian Keller 2008-12-27 15:42:15 UTC

I recently switched to the vesa driver instead of the intel driver and I noticed that gnome-settings-daemon was not starting anymore. Further investigation showed that it was segfaulting in the xrandr plugin. Removing 
~/.config/monitors.xml fixes this.
