Pinephone: Failed to set capabilities on file '/usr/bin/kwin_wayland': Operation not supported

Hi,

my PinePhone is on the unstable branch. Since the update to Plasma 5.23.2 I have issues with kwin and powerdevil. During the update there is an error on setting the capabilities:

# pacman -S kwin

The same error occurs when I try it manually:

# setcap cap_sys_nice+ep /usr/bin/kwin_wayland
Failed to set capabilities on file '/usr/bin/kwin_wayland': Operation not supported

So I guess the error was caused by an other update (e.g. the pine phone kernel 5.14.14-2?).

Best,

A kernel downgrade fixed the first error only. Now I have an other issue:

A downgrade to kwin 5.23.2 fixed this.

Check if it is a known issue, else fill a new issue:

The kernel is fixed with 5.14.15-6

Second bug is fixed with kwin-5.23.3-1.

Regarding gitlab: Why I can’t login using my Discourse account and have to rely on a third party instead?
