I run Kubuntu 22.04 on a Thinkpad W530. Kubuntu runs the Plasma desktop which is fancy and fast. 2.7 GHz and 16 GB RAM. Will take anything I can throw at it. Does everything I need. Less than 30 second start up, 5 second shut down. Rarely needs a restart on update and if so, 45 second restart.
Dang! :)
I tire of dealing with WinBS - the latest saddleburr is Win 11.
Took me three months to eliminate a svchost app that was winding up if you even LOOKED sideways at the start menu.
I'm still having issues with some app winding up RAM usage if I'm away from the box for too long - completely random, though.
