problema con GLX...

[AleX ZeTa]

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.
Created link from "/root/.kde/socket-localhost.localdomain" to "/tmp/ksocket-root"
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

Hai abilitato il direct rendering, vero?
Di solito quell'errore viene dato quando non l'hai fatto...
Dai un `glxinfo` da root pe vedere se e' attivato oppure apri il file /etc/X11/XF86Config (su alcune distribuzioni e' /etc/X11/XF86Config-4) e vai a cercare le linee:
Load "glx"
Load "dri"
nella sezione "module"
poi controlla di avere una sezione "DRI" con all'interno scritto:
Mode 0666

Credo che il problema sia questo: lo stesso errore mi veniva dato prima di abilitare il direct rendering...

qualche idea? non sono riuscito a risolvere nulla...

[andy caps]

per risolverlo personalmente basterebbe installare i driver nvidia
per il programmino non so

[xxxAlex83xxx]

infatti... commenta tutto quello riferito ai moduli DRI e installa i driver ufficiali nvidia.

Ciao!

Alex

[AleX ZeTa]

si scusate, ho risolto^^

(i driver nvidia erano installati, ma non avevo sistemato quel file)
