Strano malfunzionamento di X

[denis76]

Ora accade questo:

tomcat:/home/denis76# aticonfig | grep rendering
photo-realism in 3D rendering. Disable it to get the most accurate 3D
prevent tearing during 3D rendering.
tomcat:/home/denis76#

glxinfo | grep direct che dice ora?
dobrebbe essere Direct rendering: yes se è andato tutto bene nell'installazione/configurazione dei drivers.

[denis76]

Ottengo questo:

denis76@tomcat:~$ glxinfo | grep directglxinfo | grep direct
Xlib: extension "XFree86-DRI" missing on display ":0.0".

a me sembra corretto, magari guarda dentro al log di xorg o in /var/log/Xorg.0.log o in dmesg in cerca di warning circa la scheda, il dri o simili.

edit: hai la configurazione corretta del kernel?
http://gentoo-wiki.com/Ati#Kernel_Configuration

[denis76]

I moduli ci sono. Nel log di X trovo soltanto:

(EE) AIGLX: Screen 0 is not DRI capable


E' giusto che appaia questo?

denis76@tomcat:~$ fglrxinfo
Xlib:  extension "XFree86-DRI" missing on display ":0.0".
display: :0.0  screen: 0
OpenGL vendor string: Mesa project: www.mesa3d.org
OpenGL renderer string: Mesa GLX Indirect
OpenGL version string: 1.2 (1.5 Mesa 6.5.1)

denis76@tomcat:~$

[GreyFox86]

No, in fglrxinfo dovrebbero apparire i dati dei driver e della scheda ati, non quelli del rendering Mesa (che demanda tutto il lavoro al processore essendo rendering a livello software).

L'errore sul DRI non ci dice molto... lo sapevamo già che c'è qualcoas che non va sul DRI
Il fatto che sia AIGLX nello specifico a segnalarlo mi fa suggerire di disabilitarlo esplicitamente nello Xorg.conf, ma francamente non penso che risolverà... metti questo nella sezione serverlayout

Option         "AIGLX" "false"

Il modulo fglrx risulta caricato? lsmod | grep fglrx

Prova anche anche a specificare che proprio tutti possono avere il DRI impostando

Section "dri"
        Group 0
        Mode 0666
EndSection

[denis76]

In effetti quel modulo mi manca. Dove lo posso trovare?

[GreyFox86]

Non hai fglrx? Non hai detto di aver installato i driver proprietari ati? Se si deve esserci, anche se non caricato in memoria. Controlla l'output di modprobe fglrx

edit: fallo con X chiuso e se hai il modulo ati (quello dei driver open) caricato in memoria allora chiudilo (modprobe -r <nomemodulo>) perchè il driver fglrx per essere caricato richiede che non sia in memoria la sua alternativa open.
