I have tried installing Ubuntu 12.10 in my PC, Dell XPS L502X with Optimus (Intel i7 2630QM, nVidia GT540M).

During the installation I didn't experience any problem, the resolution it was correct: 1366x768

After rebooting the computer, the X server had an error and ask me to make a correction.

The options does appear, but I can not do anything, there is no mouse pointer, Tab and send doesn't do anything.

enter image description here

With Ctrl+F1 I change to a terminal, in the next link you'll find the contents of the xorg.log file.

I don't understand the problem, with Linux Mint 14 doesn't have any error of this kind.

Thanks in advance.

Sorry if I did a bad translation, learning Italian. :)

Problema di avvio ubunu 12.10 dell XPS L502X


ho provato a installare Ubuntu 12.10 sul mio PC, Dell XPS L502X con optumus (intel i7 2630QM, nvidia gt 540M).

Durante l'installazione non ho avuto nessun problema, la risoluzione era corretta 1366x768.

Una volta riavviato il portatile il server X è andato in errore e mi viene chiesto di effetturare una correzzione.

Compaiono delle opzioni, ma non riesco a fare niente, non c'è puntatore del mouse, TAB e invio non fanno niente


COn CTRL+F1 sono passato a un terminale, al seguente link trovate il contenuto del file xorg.log:


Non capisco il problema, con Linux Mint 14 non ho nessun errore di questo genere.

Vi ringrazio in anticipo.
