As I said, display was so badly broken with that kernel that I was unable to test, though it might have been co-incidence - it has always been rather temperamental with all the 4.1 and 4.2 kernels I have tested. In my few short tests I was unable to get the external monitor to display anything at all while the X server was active either with or without the panel open, though a VT worked. gnome-display-settings (or whatever it is called) clearly thought that the monitor was enabled though. I will give it another test next time I have to reboot anyway.
