Last week i noticed my laptop took alot of time to shut down, i thought it was frozen so i pressed the power off button to shut down. Today i had the same issue, this time i pressed some F1 to F5 buttons and a message popped up.
The countdown at the end did shutdown my system...but what is causing this ? As i dont even own a printer
If you boot again and shut-down again, is it repeatable?
I have seen screen text like this during shutdown on rare occassions, but not repeated next time.
As you do not have a Printer and not using CUPS, did you try the fix suggested in that link you posted?
I assume by that you mean:
Today again, when starting linux and do a shut down it takes 1,5 minute instead of seconds it should normally take to shut down.
