Created attachment 810023

I have a tumbleweed system with a nvidia quadro K4200 on which 2 screens are
- one on the DVI port
- the second on the display port 1 (DP1)
the two screens use resolution 1920*1080 and are defined as a virtual screen
of 3480*1080.
I use nouveau as driver; DE is KDE

This worked form years without problem. After installation of snapshot 20190708
I rebooted and the second screen doesn't more display anything.
I found that my config in
- /etc/X11/xorg.conf.d/50-monitor.conf
- /etc/X11/xorg.conf.d/50-screen.conf
- /etc/X11/xorg.conf.d/50-device.conf
has been reset to default . my config were saved as *rpmsave. I copied back the
rpmsave to the original and rebooted but this doesn't solve the problem.
The second screen receive a signal and wake up but after some seconds it
displays "displayport: no signal"
this occur:
1. during the boot when the resolution change form default to 1920*1080
2. when starting graphic display
3. on each login
4. when I start system setting

I 'll link the Xorg.0.log to this bugreport

I tested with an old kernel (5.1.15-1) but the problem is now also present
