Are you using a Wayland session?

KMPlayer hasn't been ported to Wayland. I haven't investigated why it needs to use low-level X11 calls for visuals, but until those are ported, it depends on X11.

Installed on Kubuntu 21.04 from official repository - Version "0.12.0b" Does not start from programs menu but starts from Konsole $kmplayer We have working basic Kaffeine player. Why waste time on another basic player? Dear developers, please, put efforts into one good video player for KDE and save human resources. Deprecate dead-end projects, let they mature outside KDE.
