Ora lookingglass e' anche in portage quindi la parte relativa a scaricare l'ebuild, se non tutto l'howto, e' obsoleta.
Introduzione
Bene, Sun ha appena rilasciato il suo Looking Glass 3D in GPL. Per maggiori informazioni:
- http://linuxfr.org/~pikapika/14282.html per sapere un opinione in generale
- http://forums.gentoo.org/viewtopic.php? ... ight=glass per l'esperienza dei gentooisti
- https://lg3d.dev.java.net/ sito ufficiale Sun
- http://bugs.gentoo.org/show_bug.cgi?id=55611 l'ebuild in questione
- http://wwws.sun.com/software/looking_glass/details.html qualche screenshot
Requisiti
-una buona macchina (circa 2GHz)
-un bel po' di ram (512 Mb)
-scheda video nvidia
-server X configurato a 24 bit
-gli ultimi driver nvidia
Preparazione del sistema
Prima di tutto creiamo un portage secondario aggiungendo nel /etc/make.conf
Code: Select all

Ora vi basta lanciare il comando
Code: Select all
# ACCEPT_KEYWORDS="~x86" emerge /usr/local/portage/x11-lg3d/lookingglass/lookingglass-0.5.ebuildEsecuzione
Per eseguire lookingglass dovete stoppare X (killarlo o con /etc/init.d/xdm stop). Poi lanciate il comando
Code: Select all
# /usr/share/lg3d/bin/lg3d-sessionOsservazioni
E' notevole la grafica ma il sistema e' inutilizzabile e potrebbe andare in crash da un momento all'altro.
EDIT
-------
E te pareva se non dimenticavo che questo howto e' stato possibile realizzarlo grazie al grande aiuto datomi da doom.it per la mia installazione
