After running fedup to upgrade from Fedora 20 to 21, and then to Fedora 22, I have been experiencing issues with startup and shutdown.
On reboot, I get the 3 versions on my Grub list. When I select the Grub option for Fedora 22, things look normal up to the login screen. Once I enter my credentials, they clear, but the system hangs only showing me the login background; waiting for several minutes makes no difference, system is stuck.
To solve this, I then hard reboot, and select the old Fedora 20 option in the Grub menu. When I login, everything works, and Fedora 22 loads correctly.
For shutdown, the system stays stuck in the Plymouth screen and does not power down, only by pressing the power button can I achieve this.
I suspect these issues might be related, maybe not? Anyone have some pointers on how to fix this?
