--- Comment #1 from Arch Murphy <a...@longhead.com.au> --- I just checked after rebooting and it looks like I was incorrect about the second Xorg session. It seems that as soon as I log in now (on Xorg vt1) a new Xorg is created for my login on vt2 and the original vt1 session remains with the login screen. I discovered this by checking process list as pressing Ctl-Alt-F1 to see the screen would almost certainly require another reboot. So perhaps there really are two problems? screen locker bug plasma loop bug Sorry for the confusion.
