1. After installing latest Tumbleweed with distribution with KDE Plasma end of
Aug, 2022 the dual monitor was detected, displaying background, but
non-responsive, not showing any windows.
2. Updated using zyper dup, now the second monitor is not detected at all.
3. Tried installing NVIDIA drivers from
https://download.nvidia.com/opensuse/tumbleweed, pulled using Yast (see
https://ibb.co/Hh47r9P), However, after the installation Tumbleweed loads in a
black screen, therefore I am being cautious installing it again.

bbswitch not loaded

If you want energy saving bbswitch should be loaded in intel mode.
For this package 'bbswitch' needs to be installed on your system.
Or make use of DynamicPowerManagement on Turing GPUs or later by
switching to suse-prime's 'offload' or 'nvidia' mode.
