Note: lcarsde does not bring its own display manager. If one is required (e.g. a login screen is needed but not yet there) than install a display manager like GDM or SDDM additionally to lcarsde.

Note: lcarswm uses the Kotlin compiler to build, which uses the clang compiler. clang needs an outdated library, There is usually some compatibility libraries to get it like ncurses5-compat-libs in Arch Linux's AUR. From checking the internet, it seems the most popular (and also working) solution to link to the new version, which can be done like this: sudo ln -s /usr/lib/ /usr/lib/
