About text format:
If you want to hide the text, pulse first on the icon and paste the test between “[details=“Title”]” and [/details]. About the title/link of the text, well, it’s really self-explanatory.
About your post, if your problem is that the system is taken to much time to boot up, follow this Slow system boot time
Also you can mask or disable all the services you don’t really need like cups, print service.
If you want to disable just run this sudo systemctl stop org.cups.cupsd.service && sudo systemctl disable org.cups.cupsd.service
This are some services that you can disable/mask depending of your needs
snapd.service # if you don’t use any snap applications or plan to
snapd.apparmor.service # also for snap applications
snapd.socket # also snap
bluetooth.service # it really doesn’t need to explain
-ModemManager # if you don’t use any xG interfaces
lvm2-monitor.service # if you don’t use it
Back to the issue at hand. But if you problem is about a lagging plasma, we need to see other info.
