Bug ID: 364613
Summary: plasma crashes upon hotplug of external display on
modern intel graphics
Product: plasmashell
Version: 5.6.4
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: databasede...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.6.4)
Qt Version: 5.6.0
Frameworks Version: 5.22.0
Operating System: Linux 4.5.7-200.fc23.x86_64 x86_64
Distribution (Platform): Fedora RPMs
-- Information about the crash:
- What I was doing when the application crashed:
I docked my laptop, plugged in an external mini-displayport cable connected to
a Samsung 4K monitor. Upon doing so, the screen flickered a few times, and
plasma crashed with the attached trace.
Since I have access to a variety of recently built Lenovo laptops in the
Thinkpad T series, I tested this case out on a few systems. The T430 was the
last one that *didn't* crash. The T440p, T440 and T450s all crash when
connecting an external monitor.
The only correlation I found is to the newer intel integrated GPUs which
contain eDRAM as part of the integrated silicon. See below chart for
comparison. (please excuse terrible Confluence-like formatting, I'll try to
clean it up for the report.)
