I using a thinkpad T460s, and I've tried the following:

  1. Changed QT_QPA_PLATFORM to other plugins

  2. Set hostname

  3. Checked the env variables

  4. Removed xfce

  5. Started from a fresh Arch install

This problem is not affecting klauncher alone but many other applications such as Spyder, GitKraken....

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

I'm using X11 with intel integrated graphic ( Thinkpad T460s).
I've read in other posts that the xfce might have caused the problem, but removing it didn't solve the issue.

Re: [SOLVED] Qt platform plugin

I solved the problem by resetting arch and installing a minimal plasma kde from scratch. I think the problem was conflicting packages

Re: [SOLVED] Qt platform plugin

Hello guys!
i too had the same problem with pyside6 in an arch-xfce machine.
i got it running by installing  "qt6-tools" and "xfce4-dev-tools".

i suspect the "xcb-util-cursor" package that comes with "qt6-tools" as the missing culprit.
because it is a dependency of "qt-base" package.

Hope this works for those 1000 guys looking it after 10 years XD
