The qt5- * KDE update does not start - ksplashqml Segmentation fault.

I made the Qt5- * update today and KDE does not start. I have restored the system from a backup to write a forum post.

Where should I look for a solution?

I have a window → https://imgur.com/a/svh0sWx.

My ksplashqml-20190204-161855.kcrash:

Re: The qt5- * KDE update does not start - ksplashqml Segmentation fault.

I restored the system from January 12 this year. I restarted the system. I turned off 4 of the 6 monitors. I turned the composer off. I've updated the system. I restarted the system with 2 monitors. The system turns on and after a while it hangs. No difference with composer enabled (XRendr).

I restart the computer to the effect. I turn on 4 monitors and I have an error:

The "plasmashell" process takes 200% - 500% of the CPU.

The main screen is not active. 3 have remained working. The "Start" button does not work. Other times, all 4 screens are black. I can run Yakuake (F12) or Terminator (for me, the F9 keyboard).

Re: The qt5- * KDE update does not start - ksplashqml Segmentation fault.

I have *no idea* if this is related or not, but I was having problems getting to the sddm login screen with the qt5 updates installed.
My journal was flooded with messages like 'kernel: nouveau 0000:01:00.0: gr: FECS 00000002'.
Switching from nouveau to nvidia drivers fixed it for me (this was something I had been planning to try anyway).

Since you seem to be using nouveau as well I thought I should mention it. FWIW, my laptop video card is NVIDIA GK107GLM [Quadro K1100M].

Re: The qt5- * KDE update does not start - ksplashqml Segmentation fault.

I was just migrating from the closed Nvidia drivers → https://bbs.archlinux.org/viewtopic.php … 7#p1821437.

The last update fixes the error... hmm
