I faced with two strange problems since i got updates at 06.12.2022.
- Dell Laptop with nvidia+intel graphics cards
- Plasma desktop
- 2 monitors. External is my primary and left monitor, laptop’s monitor is my right monitor.
- Using pulseaudio.
After some time of idle, my sound cards stops serving. Playback device and confguration in KDE still exists however there is no sound untill i disable and enable device. I dug in and found that this problem is happening when my device gets in sleep mode. So i commented out
# load-module module-suspend-on-idlein
/etc/pulse/default.paand problem solved. However i have no idea why i had to do that after this updates.
When i close my laptop monitor, it also turns off monitor (set in Settings->power management → energy saving ). However after i do that everything moves very slow. i can’t drag a window left to right under 3-4 seconds, games in a window gets laggy etc. Mouse moves as usual.
I discovered that if i stop KScreen2 before doing that everything goes normal. I don’t prefer disable it permenantly. But it starts becoming a headache because whenever i play a game , i have to go first
settings-> statup and shutdown -> background services and stop it.
