Bug ID: 415820
Summary: Plasma crash after resuming from a suspend and
starting to enter a password for user login
Product: plasmashell
Version: 5.17.4
Platform: unspecified
OS: Linux
Status: REPORTED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: kvanton....@yandex.ru
CC: plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.17.4)
Qt Version: 5.13.2
Frameworks Version: 5.65.0
Operating System: Linux 5.3.13-050313-generic x86_64
Distribution: KDE neon User Edition 5.17
-- Information about the crash:
- What I was doing when the application crashed:
Plasma crash after resuming from a suspend and starting to enter a password for
user login.
At first, the input field hung (keyboard and mouse did not respond)
I deleted the USB bluetooth dongle (although there were no problems with it
before, but somehow I wanted it that way)
mouse and input field still did not respond
I pressed the ctr+alt+2 to go to tty2, there the user was already authorized
earlier.
I switched to tty2 and started htop, in order to check the CPU/RAM load.
But at that moment the plasma recovered and I was thrown into tty1 and the
login screen. After entering, I saw a plasma crash message
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
