Description Wiktor 2015-11-21 10:19:27 UTC

Yesterday upgraded my Arch Linux system. After upgrade I see systemd init check, then sddm should welcome me with logging in gui, but instead it hangs in systemd console output. I'm still able to switch between other tty.

Downgrading from 5.16 to 5.15 temporarily solves problem.

Because Arch gave me best KDE experience as they provide mostly vanilla packages I've decided to create bug report in both places cause I don't know where is the problem.

I'm using vanilla kernel, and Plasma 5.4 from stable repository. System is up to date.

Reproducible: Always

Steps to Reproduce:
1. Install pkg in version 5.16.
2. Restart.

Actual Results:  
Sddm hangs

Expected Results:  
Should see logging in gui.

Comment 2 Wiktor 2015-12-04 15:47:25 UTC

There is updated package now in Arch, 5.16.0-2 which seems to have fix for this bug. Or it was something different in Plasma 5.5 Beta which I've decided to test.
