I found two ways to reproduce this bug.

1. Only suse-prime and bbswitch are installed. In this case, you need to switch
to nvidia drivers, logout, login, then switch to intel, logout, and then the
system freezes. After forced switch off and on, the booting process freezes at
the starting of X server.

2. bbswitch, bumblebee and primusrun are installed, bumblebee daemon is
configured to start on boot, the user is added to bumblebee and video groups.
In this case, system freezes on boot during starting X server.

In addition, the very presence of bbswitch and suse-prime installed screws up
the laptop sound, even if intel drivers are chosen and system does not freeze.


Hardware: Dell XPS 17 9700
OS: Fresh install of OpenSUSE 15.6 64-bit.
Nvidia drivers: nvidia-G06



Kind regards,
