[KScreen] [Bug 363238] Docked laptop lid close does not enable external monitor

So you want to switch layouts when the lid closes from only laptop screen
enabled to only external enabled?

That sounds kind of weird to me. You can achieve the same by just having the
external screen connected or not, doing it when the lid closes seems
counter-intuitive to me. Aside from that, I wouldn't know how to present it in
the UI.

Yes, but in this case, the external monitor is initially disabled and I expect
it to switch to it once the lid is closed. In this case, suspend was not
suppressed. I had to disable logind suspend events to make it work...

I cannot reproduce this bug anymore with latest git, since the Laptop now goes
to sleep - even though its on AC power and docked, while the second monitor is
connected. Stupid, but hey

Yes, indeed. I have seen your recent activity and that laptop is already
running kscreen git as of 4-5 days ago. Unfortunately, the laptop still has
issues detecting changes in monitors while docking (only discovered upon the
first xrandr call on command line). This occurs both with the intel as well as
with the modesetting driver. It might very well be a kernel driver issue?

Since it is not my personal laptop I haven't investigated further, I'll try to
have a look next weekend again.

Matthias, would it be possible for you to test the current development version
of Plasma (git master)?

We've fixed a number of bugs that prevented enabling newly connected displays
correctly, so it's quite likely that this particular problem doesn't exist
anymore. I can't reproduce it on my systems here with git master.

Hi,

Also, if you start the machine in the docker, with the lid already closed, the
composer shows both screens active, though obviously you don't see laptop
screen. This comes to a trouble when some windows turn up in the other screen.

Thanks!

Thanks for the report!

Would it be possible to run kscreen-monitor in gdb and reproduce the crash? I'd
be highly interested in the backtrace.
