Bug ID: 362119
Summary: Plasmashell crashes after screen goes into powersave
mode
Product: plasmashell
Version: 5.5.5
Platform: Fedora RPMs
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: shamim.is...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Application: plasmashell (5.5.5)
Qt Version: 5.6.0
Operating System: Linux 4.4.7-300.fc23.x86_64 x86_64
Distribution: "Fedora release 23 (Twenty Three)"
-- Information about the crash:
- What I was doing when the application crashed:
I was doing nothing. The monitor locks (kscreen). Then the monitor goes into
low power mode. On unlock, I get this. Sometimes I can't even unlock because
the password textbox cannot receive focus.,
This has been reported before but has been closed for a "lack of information".
I can repeat this behavior ON EVERY ITERATION of KDE from Fedora 21 to Fedora
23.
THis is not a lack of information issue. This is a lack of desire to fix.
Please do not mark this as a duplicate of a previous bug that has been closed
due to a lack of information.
Steps required to restore from this is one of:
1. Click restart
2. kstart plasmashell --shut-up
3. Restart the display manager using Ctrl-Shift-F2 (sometimes this fails too)
4. Reboot the system (hard boot)
Depending on the time it happens, I go through the above procesas until one of
the steps restorees my session but I NEVER reliably restart on just one of the
steps above.
This is way too serious to be a "closed due to lack of information"
I can replicate this EXACT same behavior on 4 laptops.
I have similar issues with Kwin crashing.
All machine have 16GB of memory.
Sometimes it seems like buffes and caches are taking up too much memory.
Other times, none of that is taking place.
Regardless, this is crazy. It needs to be fixed.
