I suggest to really improve the Ubuntu boot time. I’ve always known it is bad, but because i don’t boot that much i’ve always borne with the problem. After Windows 10 broke totally after an update. i just installed Kubuntu for my grandma. Now everytime she turns on the PC she asks me “Why is it so slow”, “everything is so slow”. She mentioned that it was “utterly slow” at boot and this is the truth. It is lacking very much compared to Ubuntu. So i’m giving feedback to Ubuntu/Canonical to consider really and dramatically improving the boot time. I know it’s all FOSS, it’s just a thread to acknowledge that there is a huge problem for Ubuntu in this area.
I’ve used systemd-analyze critical-chain but you just cannot go and disable every service, also there are some things there that even i don’t know what to do about. I didn’t manage to bring things any better.
