Bug ID: 381037
Summary: Plasma desktop crash after changing Nvidia Prime to
intel after reboot
Product: plasmashell
Version: 5.10.1
Platform: unspecified
OS: Linux
Status: UNCONFIRMED
Keywords: drkonqi
Severity: crash
Priority: NOR
Component: general
Assignee: k...@davidedmundson.co.uk
Reporter: ramdaniel...@gmail.com
CC: bhus...@gmail.com, plasma-b...@kde.org
Target Milestone: 1.0
Application: plasmashell (5.10.1)
Qt Version: 5.7.1
Frameworks Version: 5.34.0
Operating System: Linux 4.8.0-54-generic x86_64
Distribution: KDE neon User Edition 5.10
-- Information about the crash:
- What I was doing when the application crashed:
Nvidia graphic card was on and I change Nvidia Prime to Intel and reboot. After
reboot, I opened Blender and it worked fine but when I opened Firefox the
system froze for few minutes than KDE Plasma desktop crashed. I have a feeling
that it somehow related to Nvidia drivers. For some reason there are a lot of
troubles after I'm changing from Nvidia to Intel in Nvidia Prime.
My system:
Dell Inspiron 17R-5720 with hybrid graphics Intel and Nvidia GT GeForce 630m.
- Custom settings of the application:
I almost sure that it is related to Nvidia Prime and Nvidia driver.
The crash can be reproduced sometimes.
-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
