my system continue two graphic card (Intel + NVIDIA).
using prime-select to change between them.
i keep intel most of time.
during use intel i do next steps (the update).
i run next two command
zypper lp "to know what important security update available"
zypper lu "to know avalibale update"
the result of zypper lp was only for libyui (when search find it connect to user icon “graphic” system) plus man-pages.
the results of zypper lu is:

so i update the system using next command:
sudo zypper up
after that i reboot the system and find cinnamon crashed, on cinnamon fallback mode.
so i try downgrade (back to old NVIDIA version) using yast, but when go to the package version in yast under NVIDIA package can not find the old version.
also i find some article subject using next command to revert the update(but both command return they can not find the package):
sudo zypper in --oldpackage package-name
sudo zypper in --oldpackage nvidia-computeG04-390.144-lp153.25.1
sudo zypper in --oldpackage nvidia-computeG04=390.144-lp153.25.1
so i go to yast, uninstall NVIDIA package, delete the NVIDIA repository. reboot the system and find cinnamon work. then i think adding NVIDIA repository again will bring back the old version of drivers, but that not happens. and install same new version. so i reboot after installation finish but this time cinnamon work normal.
so why this happen? did i should flag NVIDIA drivers and system kernel with do not change (protected flag)?
also is there’s way to downgrade drivers version?
