Bug ID: 380181
Summary: Crash after desktop icons and panel go to external
monitor
Product: plasmashell
Version: 5.5.5
Platform: Ubuntu Packages
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: jose...@main.nc.us
CC: bhus...@gmail.com, plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.5.5)
Qt Version: 5.5.1
Operating System: Linux 4.4.0-78-generic x86_64
Distribution: Ubuntu 16.04.2 LTS
-- Information about the crash:
- What I was doing when the application crashed:
Opening notebook with external screen connected.
Found possible duplicate, but couldn't see how to get back to it.
I had a main panel that went to the external display a couple of days ago and
wouldn't come back when it was disconnected.
I had to add a new panel to the notebook screen (at the bottom).
It had come back to the notebook a few minutes before the crash (I had it set
to the top of the screen and set it to autohide. The HDMI to my external
monitor is still plugged in,
but I had disabled it in system settings.
- Unusual behavior I noticed:
When I switch monitors, sometimes it works fine, but a minute or two before the
crash, my notebook screen had no icons on it. This has happened before and I
have to log out and back in to fix it. Also, some sort of short tooltip was
covering part of my panel and was stuck there like the desktop wouldn't
refresh. It blocked the things that were under it.
This weird stuff seems to happen when both displays are active and I close my
notebook lid. It drives me crasy when the panel and icons just disappear.
Sometimes they end up on my HDMI screen which I never want to happen. Logging
out and back in gets my icons back, but the panel only comes back way later
after I give up trying to get it back. Even rebooting doesn't get it back.
