MuseScore 3.2.3 no Slackware Current: quase...........mas não abriu

Quase caí da cadeira quando executei o comando

mscore 

Abriu a tela de inicialização do MuseScore, mas não abriu o programa :/

Mensagem de erro foi:

QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/tmp/runtime-root'                                  

QXcbIntegration: Cannot create platform OpenGL context, neither GLX nor EGL are enabled
