@tsikas80s I hear you :( it’s the same for me. If I can’t use external monitor, my whole laptop is kind of useless…
@Spange good idea with the shorcut keys!!
In my case, I was doing fine at home, no more freezing. But now I’m back at the office and I found something very weird, which only happends if the laptop monitor is not at its full resolution.
The max resolution in my case (and also the default one, when I set the external monitor as extended of the laptop monitor in my Monitor Settings app) is 2560 x 1600
But this resolutions makes everything ridiculously small for my tasks, so I always lower it to 1920x1200. At home (LG screen) I had no problems doing that, but with this other external monitor (Samsung) this happens:
When I set the resolution to 1920x1200, the 2nd monitor does not freeze, but the mouse pointer is trapped within the primary display only!! Everything in the 2nd monitor works fine (I can do whatever is possible using the keyboard), but I can not use the mouse on this monitor. If I switch back the resolution to maximum, everything works fine again… Weird!
PS. as a reminder, I am using 525 drivers, here’s the story
