Public bug reported: Recently started experiencing issue where prime-select wont activate the intel card. Hard to pinpoint when this changed occured, as I usually use the intel card, and switching requires a reboot (the machine hangs if I do a simple logout/login or "systemctl restart lightdm.service").
