Have just developed an odd problem on a laptop running Linux Lite 1.6. I have been using it as my main PC but want to demote it soon, so detached it from my external monitor. For some reason now, I cannot get a display on the PC screen - if I detach it, on startup it displays normally, but after login goes to a dark screen with an immobile cursor on the extreme left-hand side. This is as if it is still starting up thinking it is the right hand side display (which it was), despite being detached from the external monitor, and freezing since there is no main display. I have removed the two monitor setup from the startup routine (which uses ArandR), but this has had no effect on the PC. If I restart with the monitor attached, it runs as it always did, fine, despite the startup routine being removed. The session isn't saved, so it isn't that either.
Is there a simple way to remind my laptop that it is an individual again?
