stavo facendo un piccolo software in QT... vado da console, compilo installo e avvio. Inserisco i comandi per far apparire il mio widget premo invio e mi ritrovo questo errore:

Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".
Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
Creating link /root/.kde/socket-localhost.localdomain.

Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
Xlib: extension "GLX" missing on display ":0.0".
Xlib: extension "GLX" missing on display ":0.0".

poi il widget si avvia e tutto funziona perfettamente...

come faccio a togliere questo fastidioso problema?

Grazie e ciao
