What are your tips for faster boots? My system seems to hang a bit at POST until it boots into Mint. Right after post I’ll get a blinking cursor for about a full minute until it boots in. All ssd, so I know it’s something I must have done wrong. It’s also a 14 year old processor (amd fx be 8 core, rx580), but win### booted faster on it.
fstrim.service is disk tool (that’s supposed to only be run once a week, not every time you boot) that automatically cleans up old deleted SSD data. https://opensource.com/article/20/2/trim-solid-state-storage-linux
It looks like it’s running too often, or on the wrong devices, every time you boot your computer. You can actually safely disable it; https://askubuntu.com/questions/1165128/fstrim-is-causing-high-boot-time but it’s worth looking into why it’s taking so long and being run so often.
Running this should show you the log results of fstrim doing it’s thing without actually doing anything;
sudo fstrim --fstab --verbose --dry-run
These two will show the status of fstrim and it’s autorun service;
systemctl status fstrim
systemctl status fstrim.timer
I got most of this from a quick google search; https://duckduckgo.com/?q=fstrim.service+systemd+slow You can do the same for the other major time-takers on your boot list. For comparison, here’s the top results of my semi-fresh install of linux mint;
