Comment 8 for bug 1878421

dmesg looks clean so far, intel card (internal display) is fb0 and nvidia-card for hdmi (external 4k monitor hp 27f)

$ dmesg | grep frame
[ 0.882504] efifb: framebuffer at 0x80000000, using 8100k, total 8100k
[ 0.882611] Console: switching to colour frame buffer device 240x67

see full dmesg in attachment

strange is that i have no X.org.log in /var/log, anything i can try to workaround/test for affected Package?

noticed, that on login-screen the background of external monitor is purple and switches to black (default color without background-image)
