Bug Description

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?

How do you confirm that login-logout works before?

I only had this in 18.4 and 20.4,but had not tried older versions after noticed it.but i remembered in any previous version reboot was not needed.

I found a github-repo describing the difference,but had not tested it because it is not designed to be working on 20.4.only tried lightdm,but no difference.
