Salve lista.<br><br>Devo reinstallare Ubuntu 10.04 sul mio portatile e vorrei un consiglio: č meglio reinstallare la versione a 32 o a 64 bit? Di seguito vi posto i risultati di alcuni comandi che ho dato per capire la struttura della macchina:<br>

*fine citazione*<br><br>Mi sembra di capire che la macchina č in grado di supportare il 64 bit, ma attualmente ho installato il 32. Leggendo su vari forum mi sembra di capire che non ha molto senso installare Ubuntu a 64 bit se si hanno meno di 4 GB di RAM (quindi a me non conviene...?). Voi cosa ne pensate? Grazie!!!<br>
