DESCRIPTION
Hi! I’m a bit of a newbie at Linux (hence the “easymode” distro), and as such
I’m not sure I’ll be able to give all the information I need to. Please don’t
hesitate to ask for extra information if it can help diagnose the issue.
I’ve asked around every place I could find for support on Bazzite specifically,
but the only response I got was to try asking KDE for help, so here I am. I
asked on KDE Discuss, but no solution was found there. So submitting a bug
report is my last resort.
[KDE Discuss thread:
https://discuss.kde.org/t/screen-will-sometimes-refuse-to-turn-off-and-i-dont-get-it/48442]
I apologize if this issue is not KDE’s fault. I don’t have a good understanding
of what issues may be in the scope of the various parts of my OS: Linux,
Fedora, Bazzite, Wayland, KDE Plasma…
I’m using Bazzite DX KDE 44, which comes with KDE Plasma 6.7.1 and KDE
Frameworks 6.27.0.
I have my PC set up to dim the screen after 1 minute of inactivity and turn the
screen off after 10 minutes of inactivity. It never goes to sleep (I use it as
a Jellyfin server, so it would be a problem if it did go to sleep).
Often, but crucially, not all the time, when I walk by the PC after it’s been
unused for a long time, I see the screen on. The screen is always dimmed (if I
move the mouse the brightness shoots up), so I know it’s considering the PC
“inactive” at that point.
Whenever I try to sit down and diagnose the issue (set it to 30 seconds to dim,
1 minute to turn off), it always DOES turn off the screen. But in actual usage,
most of the time it doesn’t. I’ve tried closing an app, walking away, and
coming back 10 minutes later to the screen still on, closing another app, rinse
and repeat until there are no apps running anymore. Steam, qBittorrent,
Firefox, Thunderbird, Docker (with Jellyfin and Shoko) none of these is the
culprit.
I thought I had a bright idea. I disabled clipboard syncing in KDE Connect.
Maybe it was phone usage that woke my PC up. The PC turned off its screen ONCE
after I disabled it. I thought I had found the issue.
But the following day it was back.
Another suspect was the HDMI cable connected to the TV, or the Mac laptop
connected to the same monitor. Maybe something was periodically causing the
monitor to auto-switch inputs (auto-input switching can’t be turned off on this
one) which would “wake up” the screen every time. But no, unplugging every
other device from the screen did not change anything.
Yet another suspect was USB devices, specifically my UPS’s battery status
monitoring USB cable. I unplugged it permanently; I don’t really need that. But
no change to the issue. The PC’s screen is still occasionally, unpredictably on
when I walk in.
I don’t have many USB devices plugged in: two 8bitdo controllers, keyboard and
mouse, a printer, a headset,USB hubs and a switch that I use to switch my
keyboard, mouse and headset between my personal and work computers, and another
USB hub on an extension that is used to extend USB connectivity to the living
room where the controllers are. And crucially, the controllers on the long
extension aren’t even able to turn the PC screen back on no matter what I do
with them. When I sit down to game and the screen is off, I need to open KDE
Connect and move the mouse a bit to see anything.
At this point, my only idea is that having KDE Connect set up AT ALL may be
causing the issue. But I can’t afford to turn it off entirely. My phone is how
I control my PC from the couch when I need to do anything my controller can’t.
My friend came over and ran a bunch of commands to try and diagnose the issue.
He saw nothing preventing inactivity/sleep/etc., and indeed everything was fine
(as it always is whenever you sit down and reduce the time to turn off screen
to diagnose issues).
I just do not understand this issue and I don’t know how to dig further into
it.
STEPS TO REPRODUCE
1. In System settings > Power management, set PC to Dim automatically after 1
minute and Turn off screen after 10 minutes. (When inactive: Do nothing in the
Suspend session section)
2. Wait.
OBSERVED RESULT
Screen always dims after 1 minute, and always turns off after 10 minutes.
EXPECTED RESULT
Screen always dims after 1 minute, and will only sometimes turn off after 10
minutes. Most of the time, it stays on forever.
