Hello folks! Recently I installed plasma5-mobile on a Surface Go running Tumbleweed KDE and used Plasma Mobile session for a while. It felt clean and nice but overall didn’t fit my use case. So I decided to move back to desktop session and this is when the issue occurs.
In Plasma Mobile the frame and titlebar of supported applications would be hidden and app windows would be maximized by default, which is reasonable for phones and other mobile devices. After I changed back to Plasma Wayland and uninstalled plasma5-mobile the titlebar reappeared but theme could no longer be changed.
I tried setting global theme, or rename ~/.config/kwinrc, but the issue remains after reboot. I wonder where I should go check and what caused the issue. In another word, what did plasma5-mobile do to config that changed the window behavior and how to recover it?
I created a snapshot before installing plasma5-mobile (why not?) and going back to that snapshot did not solve the issue. So I think the problem lies in my home directory.
To check that, create a new user and see how that one fares.
And for your own user, you could remove all in ~/.config and ~/.local/share that looks as belonging to KDE.
You could even clean both, but that would also remove config changes you did to some other programs.
Thanks a lot! I was wondering whether cleaning old configs would be too much but your words gave me confidence. And instead of removing them, I found it better to rename them so that I can keep old configs and see what caused the problem. Though I failed the latter one, re-login did bring everything to default including the titlebar. Restoring some configs took a while but as I have made a backup it was not painful.
Indeed , renaming is the better option of the way of removing. I did not mention that because that looks logical to me. Also restoring from your backup would be a possibility that I do not mention as being too basic a thing.
