I notice that my computer takes nearly two minutes to boot in the morning and the first load of any program also takes a long time. I am running Kubuntu 20.04 on a dual core homebuilt computer.
Hardinfo gives: Processor : Intel(R) Pentium(R) CPU G3420 @ 3.20GHz Memory : 8037MB (4978MB used) Machine Type : Desktop Operating System : Ubuntu 18.04.2 LTS User Name : peterm (Peter Merchant) Date/Time : Wed 25 Mar 2020 10:02:24 GMT -Display- Resolution : 1680x1050 pixels I came across an article in Feb 2019 Linux Format about bootchart and the discussion there is about using systemd-analyze blame which shows how many units are running and how long they take to start. BUT, which ones can I remove? Being just a user and not a guru, I don't know what many of these do or if they can be removed safely. Thanks for any advice. Peter.
