Personally, I would prefer, in those scenarios, the monitor be treated as different as long as it remembers it. I don't mind having to setup / re-setup a couple of desktop settings per "monitor configuration" once and some of those scenarios really wouldn't happen if the monitors are in the same place except in major edge cases. Really, as long as I don't have to do it after every time my monitors go to sleep and plasmashell crashes and suddenly KDE thinks I have new monitors / forgets the background / flips the task bar from one to another, etc... I'll be ecstatic. -- You are receiving this mail because: You are watching all bug changes.
