Happens to me too on HP Zbook 15 with (Nvidia/Intel) only Nvidia active. Disabled intel card in bios.
Workaround: Add "nogpumanager" to GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub and execute update-grub to disable gpu-manger. /var/log/gpu-manager.log log_file: /var/log/gpu-manager.log last_boot_file: /var/lib/ubuntu-drivers-common/last_gfx_boot new_boot_file: /var/lib/ubuntu-drivers-common/last_gfx_boot grep dmesg status 256 dmesg status 256 == 0?
