I am also experiencing a long boot time (5 minutes)on one of my computers with 17.1 (vs 24 seconds with 16.1). I also see a tpm (trusted platform module) error. My UUIDs in fstab and by blkid are identical. I also have a black screen (?no backlight) for most of that time.
My boot option editing doesn’t seem to take properly. I tried eliminating quiet and splash options and used xorg=intel without any change.
Except, after editing and rebooting several times, now I seem to go only to a console login. Startx doesn’t work. There is a message about lacking an xauthority file.
When it was launching to a desktop, the system worked ok.
I have wacom digitizer on this computer. Version 16.1 didn’t apparently detect or load that, while 17.1 does, so I suspect that it may be related to the initialization of the wacom files. (The Xorg.log file goes from 68 seconds at one point while working on the serial wacom driver to 312-319 seconds before then starting on the wacom stylus.
Apparently, the OP’s computer doesn’t have a wacom digitizer…
Hope that suggests something.
