OK, by that logic, it should be arch then 😃👍 (I think that to get the system working again if the DE crashes, I have to install a new DE through the terminal, control + shift + t I think, and then start the DE session through the terminal.)

What? 😐

I can run KDE with Kubuntu well

I can’t upgrade, I will try arch. If I can’t, endeavour.

Can you recomend a tutorial?
