In questa pagina è riportato il resoconto dell'installazione di Ubuntu 7.04 «Feisty Fawn» e Ubuntu 7.10 «Gutsy Gibbon» sul portatile Asus M6Va.

Inoltre verranno riportate le informazioni generali sul riconoscimento dell'hardware e i possibili metodi di installazione.

Rilevamento dell'hardware

Dispositivi connessi

Per verificare il corretto rilevamento dell'hardware del portatile, è sufficiente aprire un terminale e digitare il seguente comando:

Qualche accorgimento:

sudo apt-get remove powernowd

sudo apt-get install cpufrequtils sysfsutils

Semplice trick per utenti Gnome:

sudo dpkg-reconfigure gnome-applet

Rispondete YES alla domanda che verrà fatta e potrete modificare frequenza e profilo della CPU con un semplice click sulla applet CPU Frequency Scaling Monitor presente nel vostro pannello di Gnome.

Considerazioni

AIGLX e CompizFusion perfettamente funzionanti con i driver OPEN;
TV OUTPUT e DUAL MONITOR funzionanti solo in modalità CLONE con i driver OPEN;
Per abilitare Xinerama sono necessari i driver PROPRIETARI (fglrx) con conseguente impossibilità di utilizzare AIGLX;
Per conservare gli "effetti desktop" con il DUAL MONITOR è necessario installare XGL (non sempre funzionante).
