I have a somewhat ANCIENT Dell Latitude 2100 notebook which originally shipped with Ubuntu 9.04. It has been a great little toy and for the past several years has served as a jukebox in my workshop. It is powered by an Intel Atom processor, has a decent SSD and the maximum of 2 GB of RAM.
In its role as a jukebox it originally had 12.04 or 14.04 I am not sure. It has been do-release-upgrade updated through to 18.04. Following the upgrade to 18.04 it seemed that it was much slower to boot. I replaced it with a Raspberry Pi3B+ this past weekend and did a clean install of 18.04 - in case the multiple upgrades were an issue. It seems they were not.
18.04 takes 80 seconds from power on to the login screen and 40 seconds from submitting my credentials until the panel will respond and launch a terminal.
I installed 16.04 and the same tasks take 25 and 20 seconds respectively.
Any suggestions as to how to improve the 18.04 boot time?
I have read that 16.04 Mate is only supported through April 2019 where as the base Ubuntu is supported through 2021. Can someone confirm that this is true?
I am sort of in a quandary as to which version to run.
