Freezes and slow performance

Hey all,

Have been a happy Manjaro user since ~6 months. However since around 1 or 2 weeks, my system has had many issues. A few examples:

  • When copying a screenshot to the clipboard, flameshot crashes and freezes the UI
  • Adjusting brightness using the buttons has a ~30 second delay
  • Firefox freezes and crashes regularly
  • Opening anything from the tray takes around 1 minute (nm-applet, blueman, pamac, volicon, etc)
  • Starting a filemanager (nautilus or pcmanfm) takes around 30 seconds

The problem does not seem related to swapping (problems happen when I have lots of free RAM), nor to disk io (iotop shows low rates often).

Anyone an idea how to start fixing this?

My view is that it does not happen by itself. You probably installed something what causes the problems.

Hmm, looking through my recently installed packages I'm not sure what i'm looking for. Since it seems so fundamental, would it be kernel related? I seem to be running an LTS kernel though.

I do not think it is kernel, it would be something like another DE or part of it, hard to say.

Oh my! Seems like you might be right. As part of installing kdenlive I somehow ended up installing KDE... Removing it seems to be the solution so far. Will report if not.

Thanks
