External (thunderbolt) monitor frequently freezes

I didn’t find my model number in the first link. And I removed supergfxctl, asusctl because they were causing problems with a new kernel.

Should I reinstall?

I installed the asusctl and supergfxctl package, the issue still persists.

I didn’t glean much from the thunderbolt page. Did install the plasma-thunderbolt package and reboot. Should this be enough?
