Hi. I'm a newbie BSD user. Before I tried to use FreeBSD, managed to install KDE but it was too slow. So I decidec to give a chance to GhostBSD. Drivers are automatically loaded. I tried to install KDE, remove LightDM an install SDDM, but couldn't managed to boot KDE. May I install KDE on GhostBSD?

Yes, but it is not configured to boot by defaults.

you will need to do sudo rc-update add sddm default to boot to SSDM.

It worked. Thank you
