Maybe it's a little better, but not there yet. I have two monitors
attached. I tried running Creator and Assistant, then running my script
which uses xrandr to remove and re-add the displays. I tried this first
in a Plasma session. When the screens came back to life I had only a
black screen (k

Upstream has struggled for a long time with these problems, and we have
plenty of backported fixes from Qt 5.6 branch in our 16.04's Qt 5.5.
Sadly they don't fix all issues still.
The next upload is already being prepared and is at

I'm currently on 5.5.1+dfsg-16ubuntu7, which should be newer and include
these, no?
I found this digging into why xenial's kde5 plasma shell and all kde
apps keep freaking when my 4k displays go away. Like others, I use big
4k tv's (3x of them) that give no signal when they power down, so the

Thanks for testing both of the new versions, at least it does not
regress from the 5.5.1+dfsg14ubuntu2. Potentially the new patch helps in
some situations as it did for Paul who submitted it to 5.6.

I'm seeing similar behavior to the previous PPA, when the screens are
disconnected the panel fails to resize, and when the screens are
reconnected plasma segfaults. Note that in my configuration, the
internal display is disabled by kscreen to allow both external monitors
