Why on earth does the sendmail service need to run? I don't even run a mail server.
hey, I am not messing with anything right now. Some recent updates have not been so great. Gnome Shell keeps consuming memory till it reaches 2GB or more after a few hours and it brings everything to its knees. I found out that my Wacom tablet not functioning is not the fault of the stylus or the tablet but because of some crazy stuff that gnome-shell is doing - probably being a memory whore.
Anyway, the point of all that is rebooting solves several issues. It clears up the memory once more, the stylus works once more, R does not crawl etc. But of course then I have to face a 2 min boot sequence.
I am going to just take your advice and not do anything. But yeah, instead of messing with the system, I actually think I am going back to vanilla ubuntu after I am done for good.
I love (e:Paul)'s advice!
You can turn off sendmail but I wouldn't start messing with your machine services right now. Just live through the 60 seconds boot time until you dissertation is done. Otherwise, you are bound to fuck it up and have way more downtime. Here is a great overview of working with systemd :::link:::
I lied mine says it took 50 seconds, I swear its faster than that. Maybe the last boot was slow, I did have a kernel update.
you can disable whatever services you dont want. This is even more interesting systemd-analyze plot > graph1.svg
That is so crazy. My system boots in like 10 seconds. Maybe its worth investing in an SSD.
