Bug ID: 450980
Summary: KDE 5.24 breaks suspend to RAM (really badly);
reverting to 5.23 resolves it
Product: kde
Version: unspecified
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: major
Priority: NOR
Component: general
Assignee: unassigned-b...@kde.org
Reporter: windows2li...@zoho.com
Target Milestone: ---
Starting with KDE 5.24, when I tell my laptop to suspend to RAM, the following
occurs:
* It "appears" to suspend. (Fans stop, external monitor turns off)
* But the CPU is COOKING at maximum heat, without any running fans!
* Pressing keys on my wireless keyboard or mouse does NOT wake up it (as it
always has before)
* I need to "wake up" the laptop by pressing on the actual laptop keyboard
* When it "wakes up", the entire laptop feels like it's COOKING. Apparently,
the CPU was still running, but no fans were running to keep it cooled.
With 5.23 and earlier:
* The laptop correctly suspends to RAM
* Everything stays cool (CPU is not running)
* Pressing a key on my wireless keyboard or mouse wakes up the laptop
* No issues at all, laptop feels cool
I have an external monitor attached to the laptop, which works properly.
I had to revert back to KDE 5.23, since this bug was literally FRYING my laptop
to ungodly levels of heat. (Had I not noticed earlier and reproduced it
consistently, I could have risked damaging my components.)
Was there a change done to the "power" side of things from 5.23 -> 5.24?
To reiterate: It's specifically KDE 5.24. Trying a different kernel makes no
difference.
SYSTEM INFO:
Operating System: Manjaro Linux
KDE Plasma Version: 5.24.2
KDE Frameworks Version: 5.91.0
Qt Version: 5.15.2
Kernel Version: 5.16.7-1-MANJARO (64-bit)
Graphics Platform: X11
Processors: 8 × 11th Gen Intel® Core™ i7-1165G7 @ 2.80GHz
Memory: 15.4 GiB of RAM
Graphics Processor: Mesa Intel® Xe Graphics
I have a desktop PC with the same software, however, it uses a discrete GPU
(Nvidia), which does not have this issue with KDE 5.24.
What other information would be useful?
Thank you.
