Public bug reported:

in previous ubuntu versions (<18.4) it was posible to switch hybrid
graphics with only logout/login, but not with 18.4+ including 20.4

tried also with lightdm instead of gdm3, same result and more problems
(not working fingerprint, tap2click and larger cursor)

is it possible to select card by commandline (in grub) to avoid
rebooting after switching?
