Since slightly less than a week ago my machine refuses to complete a boot to the graphical login screen. during the boot I get a failed wait for Plymouth Boot Screen to quit message. Checking journalctl -xn and systemctl service status (? I have not copied that exactly) regarding plymouth-quit-wait shows nothing further than it has failed to start. I have no real idea on where/how to proceed from here.
I can Ctl-Alt F2 and get a non graphical login.
I have tried issuing a systemctl start plymoth-wait-quit.service there (ie in tty2) and get the same error message.
I have also tried a startx which reports it cannot find an Xserver (nor a graphical display device) -- I haven't written these messages down exactly.
I am writing this from the booting and working windows partition on the machine.
Any suggestions on what to look for /look at?
