Oggi quando ha acceso il pc tutti gli effetti visivi di compiz erano disabilitati, provando da aspetto ad attivarli ricevevo il messaggio IMPOSSIBILE ATTIVARE EFFETTI VISIVI (o qualcosa di molto simile) quindi ho seguito questo post
http://forum.ubuntu-it.org/viewtopic.php?t=188188
per cercare di risolvere il problema. (poi l'ho risolto reinstallando la scheda video)
Nel post era indicato di controllare il file /usr/bin/compiz, io l'ho fatto e ho notato una cosa: pur avendo una scheda video da 256 MB in quel file è indicato che è da 64! Ora vi posto il file

Forse ho sbagliato driver? Oppure qualche cosa nell'installazione? Per farlo ho seguito questa guida
http://telperion.wordpress.com/2007/05/ ... an-ubuntu/
Qualcuno può aiutarmi?
Grazie mille a tutti!
