I am a bit confused: Was this an upgrade or an fresh installation?

If it was an upgrade, HOW did you upgrade? With the zypper method or booting into an installation ISO and then doing a YaST-based upgrade?

On beforehand I had LP15.5 installed, but had replaced the previous Nvidia card with another Nvidia gpu model. 1. I booted from from a USB stick (with openSUSE-Leap-15.6-DVD-x86_64709) with a Display port cable connected to the current Nvidia gpu and the monitor. The boot menu displayed OK, I tried first an "Upgrade" from this menu, but the signal disappeared with a black monitor after a while (possibly before the green progress bar started). I thought an upgrade was not possible, due to the replaced Nvidia card (new hardware) and that I had to do a new Installation.

I suspect that there was a short while where the NVidia drivers were not available.

2. I rebooted the USB iso again and selected "Install" from the menu. The same thing happened, with a black monitor after a while. Not a short time, because I waited several minutes, and I got the impression the installation had terminated (not sure). 3. Then I replaced the DP cable with a DVI-D cable, booted the USB installation menu again and did a new Install from here. The installation went as it should and displayed continuous without loss of monitor signal. (Later on I replaced LP15.6 with a new Slowroll installation on this disk, installed LP15.6 on another disk in dual boot, quite ok with the DVI-D cable connected.) I don't understand why the DP connection did work work up to and included the boot menu, while the whole installation went fine continuously only with a DVI-D connection. With another monitor without DVI-D port, this would not have been possible. -- You are receiving this mail because: You are on the CC list for the bug.
