Checked LM17-64 Cinnamon and it has a directory Plymouth.
Don't know the importance of that though
I am hunting the cause of this
I am using LMDE and I *don't* have the directory named /lib/plymouth
on my system, yet starpar
on my system attempted a start of plymouth
It appears that plymouth
provides services for mdm
(Mint's windows manager) in all editions of Mint except LMDE.
Yours is the first response to my open question (I've sent several PMs to others who've had this error - the one reply to date says he *is* using LMDE) and, as a Mint user not using LMDE, you have the directory /lib/plymouth
Good to know, and its consistent with my working hypothesis.
Thanks for your reply.
