Created attachment 141521
  --> https://bugs.kde.org/attachment.cgi?id=141521=edit
New crash information added by DrKonqi

plasmashell (5.22.5) using Qt 5.15.3

- What I was doing when the application crashed:
Connected two external displays
Bottom panel disappeared from Plasma desktop
Used system preferences to reset layout to theme defaults to force panel to
reappear

- Unusual behavior I noticed:
Bottom panel disappeared from Plasma desktop until reset layout

Definitely an issue for me. Also seems to be triggered when changing resolution
on the primary monitor after disconnecting a second monitor.

Still seems to suffer from the same issue when I swap between using my 2
different laptops, both having my external monitor attached via HDMI. The
external screen has a higher resolution (not sure if that matters). Oftentimes
when I switch from 1 laptop to the other, and I alter the source of my external
monitor (through buttons on the screen), the monitor ends up with a desktop but
no KDE taskbar at the bottom. At that stage, even if I press F10 and manage to
go back to 2 screens, neither of the screens will have a taskbar. That means a
hard reset is the only way I know to deal with this.

I forgot to say this has happened to me using every single Plasma version for
the last 2 or 3 years. That's the time I'm using Linux.
On several computers.

Almost every time I have 2 video outputs and I change something using Switch
Display (Meta + P) the panel disspears when I reboot.
In my case I use a monitor and a TV.
I'm forced to set the output to Unify Outputs and don't change it.
I always solve it with Timeshift restoring my last system backup.

I also have the problem in Fedora 24. I have 2 monitors (HDMI + DisplayPort).
When I disable HDMI output in kscreen, the taskbar disappear.

Executing this:

[plasmashell] [Bug 356727] Plasma Panel sometimes disappears with multiple monitors

[Fabio Coatti via KDE Bugzilla]

https://bugs.kde.org/show_bug.cgi?id=356727

--- Comment #28 from Fabio Coatti  ---
Same problem here, with 5.5.4

two monitors setup, the behaviour is a nightmare: standard panels appears and
disappears when plugging on and off the external monitor; the absolute chaos is
when the laptop goes in standby mode when not connected to external monitor and
wakes up with two monitors. 
It also happens to have the default panels duplicated, one per screen.
Even wallpapers are swapped (that is to say, a wallpaper initially placed on
external monitor, after reboot it appears on laptop screen even with the
external plugged in).

Sometimes I can fix (well, improve a bit) things by logging out from kde and
editing plasma-org.kde.plasma.desktop-appletsrc by changing all lastScreen=1 to
lastScreen=0

I don't know if this can be related to wrong rc file creation or what else.

If needed I can provide more details or debug info or even compile with
patches.

Thanks.

I am running Kubuntu with Plasma 5.5.3 from the backports PPA.

I can confirm this bug. Here is the behaviour for me:

I have a laptop running at 1920x1080 with the default panel.

I plug in a second monitor running at 1920x1080 and configure it to be the
primary, and disable the laptop panel.  The panel moves to the external
monitor.

I unplug the external monitor. The panel disappears. I plug the external
monitor in again - the panel reappears.

It is a similar issue if I unify the outputs across both monitors - unplugging
the external monitor makes the panel disappear, plugging it in again makes it
re-appear.

Thanks

I have this problem also here running Fedora 23.  I have not been able to get
the default panel back, so I have had to add a new one to be able to work with
the laptop. Just like cher...@aip.de, I use the laptop to give presentations,
and the disappearing panel is certainly not helping out.

Restarting plasmashell  has not helped. In the course of my tests, I have seen
the newly created panel going to the external monitor, so that there were two
panels there and none in the laptop screen which, by the way, is the primary
output all along.

Confirming bug because it affects multiple users spanning over quite a few
reports which are marked as duplicates of this one (bug 353426, bug 347195).
Unfortunately were the other bugs about the plasma panel generally
disappearing, not only on drag & drop; I thus changed the subject to be more
generic.
