Detect new monitor without needing to log in again

Postby palimmo » 15 Oct 2017 19:28

Hi.
Sometimes I connect my external monitor after the login. Unfortunately Displays seems not able to detect it immediately and I have to log out and log in again to see it.
How can I solve this problem?
thanks

No real solution, sorry. But you could try arandr. I'm using arandr for 2 monitors. Sometimes they get allocated the wrong way and clicking "apply" in arandr forces the displays to reload. I'm on XFCE though.

I'm afraid not. I just have one monitor. If nobody answers here, it's usually so specific that nobody has any experience with it. Sorry.

Did you try arandr as I said? Did it not work?

arandr works very well: as soon as I start it, the external display is immediately detected.
However it is incredible that kde plasma is not able to manage it... :(
