Hello !
Im opening this topic, because im experiencing a lot of problems after the Wyndsdey update.
I was using KDE5 with X11, it was fine.
I was stupid enough to update the system while i was logged in.
Now in experiencing very slow I/O performance in the X11 session.
Now the wayland session is available, i tried it, the UI feels more responsive, but the i/o slowness still persists, maybe not that bad like in the X11 session.
I read that KDE 6 introduced a bug where the bluetooth service constantly polls the devices on the main thread, that is causing the slowdown.
However, im on the latest stable KDE version, and the problem still persists.
I set back the theme to Breeze, and disabled the login greeting screen.
Maybe someone can help me troubleshoot the root cause:
- VERY slow I/O performance, cant even play an mp3 song without lagging and buffering, laoding a CS 1.6 map takes minutes, firefox is dead slow, it takes minutes to load my emails, (chrome is fine for some reason).
- CS 1.6 freezes for seconds during play,
- CS 1.6 black horizontal lines splashing randomly (wayland related).
- Booting and shuttind down takes a minute or two instead of 15s like before the update (the quiet and the splash kernel parameteres somewhow disappeared, now it shows log messages during booting and shutting down)
The boot and shutdown process stops at mounting/unmounting my hard drives for around a minute. - Websites in Chromium flashes randomly (wayland related?)
- High CPU usage on idle
Actions that i already did to mitigate this problem after the update:
- resetting KDE configurations
- added fb_dev and modeset kernel parameters
