||<style="border:none;"><<Immagine(./apple-macbook-pro-15-8.2.jpg,150,)>> ||<style="border:none;">In questa pagina sono riportati il resoconto dell'installazione di '''Ubuntu 17.04''' e le informazioni sul riconoscimento hardware del portatile '''Apple !MacBook Pro 8.2'''.||

<<Anchor(install)>>
= Installazione =

||<tablestyle="text-align: justify; width:60%;" style="border:none;" 5%><<Immagine(Icone/Grandi/info.png,,center)>> ||<style="padding:0.5em; border:none;">Rispetto alla dotazione hardware fornita dal produttore, sono presenti 16 GB di RAM e l'hard disk originale è stato sostituito con un SDD.||

Nonostante '''Ubuntu''' riconosca sia la scheda grafica integrata '''Intel''' che la GPU discreta '''AMD Radeon''', non riesce a gestire lo switching tra le stesse. Pertanto la procedura di installazione non arriva a buon fine. 

Per utilizzare una '''live''' e portare a termine la procedura di installazione, è quindi necessario un piccolo accorgimento per disabilitare la GPU discreta '''AMD Radeon'''. Seguire i passaggi descritti di seguito:

 0. Avviare il computer con una [[Installazione#Creazione_e_avvio_del_supporto_di_installazione|live]] di Ubuntu (su chiavetta USB oppure su DVD), tenendo premuto il tasto '''ALT'''. Alla schermata del boot manager, selezionare '''EFI boot''' quindi premere Invio.
 0. Al caricamento di [[AmministrazioneSistema/Grub|GRUB]], selezionare '''Try Ubuntu without installing''' per la live oppure '''Install Ubuntu''' per l'installazione diretta e premere il tasto '''e''' per editare il codice di boot.
 0. Individuare la riga contenente {{{
load_video
}}}
 0. Dopo la stringa individuata, aggiungere le seguenti righe: {{{
outb 0x728 1
outb 0x710 2
outb 0x740 2
outb 0x750 0
}}}
 0. Premere '''F10''' per continuare la procedura di boot e iniziare  l'[[Installazione/InstallareUbuntu | installazione]].

||<tablestyle="text-align: justify; width:100%; " style="border:none;" 5%><<Immagine(Icone/Piccole/warning.png,,left)>> ||<style="padding:0.5em; border:none;">'''Questa modifica dovrà essere resa permanente, altrimenti il sistema si bloccherà su una schermata nera ad ogni avvio. Per fare ciò, seguire le istruzioni del [[#gpu|paragrafo dedicato]].''' ||

= Rilevamento dell'hardware =

== Dispositivi connessi ==

Per verificare il corretto rilevamento dell'hardware del portatile, digitare in un terminale il seguente comando:
{{{
lspci
}}}

Il comando precedente restituirà una schermata simile alla seguente:

Come detto nella [[#install|sezione dedicata all'installazione]], è necessario disabilitare la GPU discreta '''AMD Radeon'''. Seguire la procedura descritta di seguito:

 0. Aprire con i [[AmministrazioneSistema/Sudo|privilegi di amministrazione]] e con un [[Ufficio/EditorDiTesto|editor di testo]] il file `/etc/grub.d/10_linux`.
 0. Individuare la riga contenente {{{
echo " insmod gzio" | sed "s/^/$submenu_indentation/"
}}} 
 0. Immediatamente prima della riga individuata inserire {{{
echo " outb 0x728 1" | sed "s/^/$submenu_indentation/"
echo " outb 0x710 2" | sed "s/^/$submenu_indentation/"
echo " outb 0x740 2" | sed "s/^/$submenu_indentation/"
echo " outb 0x750 0" | sed "s/^/$submenu_indentation/"
}}}
 0. Salvare le modifiche effettuate e chiudere il file.
