What system do you have (Arch, Kernel, HW)? Does it happen with other DEs or just with KDE ? Ist it a recent observation?
Kernel~4.13.11-towo.1-siduction-amd64 x86_64Plasma 5.10.5, Frameworks 5.37.0, QT 5.9.2
This started happening maybe 10 or so du's ago. And has been a problem through several kernel versions. I'm pretty sure it started after a KDE update, but I didn't put together which one.
I've searched everywhere, the closest thing I've found was to turn off the KDE splash screen, that didn't help. None of the systemd analyze reports give any clues.
Booting in general is ok, the problem seems to be KDE startup. I've tried making a new user and logging in from a clean KDE desktop, that didn't help either.
I'm quite frustrated. My system was working so great, it still is except 2-3 minutes is a ridiculously long time to wait. Once I'm in, everything is reasonably fast and normal.
