after upgrading to 12.04 I've encountered the following problem with
gnome3 desktop:
I have 2 screens for my laptop (dell xps502z), one at home and one at
work. they have different resolutions, and both connected via the mini-
displayPort socket (the hdmi socket on this dell doesn't work due to
Nvidia Optimus crap).
When moving from one monitor to the other, the monitor doesn't get a
signal. Opening the display manager shows the screen blackened, and
trying to enable it brings about the following error:
GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface
`org.gnome.SettingsDaemon.XRANDR_2' on object at path
/org/gnome/SettingsDaemon/XRANDR
restarting X11 solves this, but of course means I have to exit any open
window, and reconfigure my dual monitor layout each time. this was 100%
fine in 11.10.
this happens when moving from either screen to the other.
