I have a small funny problem that I have to disconnect and re-connect my keyboard after boot before I can type password to login into KDE Plasma.
The problem is definitely Xorg / SDDM / Plasma since my first NixOS generation was without X and I didn’t have that problem. But then when I configured plain simple Plasma: KDE - NixOS Wiki
it started happening. I can change generation in Grub so keyboard is just fine and something kills it before or immediately after I see graphics.
Is there anything I could try to disable / change?
