Hello M.Penalver
Sorry for my english
I try the iso in http://cdimage.ubuntu.com/daily-live/current/   for i386.iso (13.10) but the result is not positive
When i start i must push on light+ to see something on the screen and if i choose in the menu i have a screen with 
Ubuntu in the middle and 5 points under the word Ubuntu and finaly the screen change for lines and noises , i must close when bouton off,i retry with options nomodeset, acpiosi etc.. (all on my Acer Aspire 5736z) but i have the same when i boot on my Packard Bell Easy Note.
Can you solve the problem ? 
apport-collect -p linux 1051824 do not run because :
You need to run 'sudo apt-get install python-apport' for apport-collect to work.

Aucune version du paquet python-apport n'est disponible, mais il existe dans la base
de données. Cela signifie en général que le paquet est manquant, qu'il est devenu obsolète
ou qu'il n'est disponible que sur une autre source
Cependant les paquets suivants le remplacent :
  apport

E: Le paquet « python-apport » n'a pas de version susceptible d'être installée

Title:
  [regression] Acer Aspire 5736z needs nomodeset or acpi_osi=Linux

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Reported by pescadou999 on the ubuntu-fr forum ( http://forum.ubuntu-
  fr.org/viewtopic.php?pid=10790101#p10790101 ).

  Acer Aspire 5736z
  There was no problem with default settings in 10.04.

  Since 12.04 (tested with default kernel, and with 3.6.0 mainline):
  - default settings: very low brightness (it is very difficult to see the login screen appearing). The Fn+brightness keys have no effect.
  - with 'nomodeset' on 12.04: brightness is ok, but the screen resolution is bad (image is distorted)
  - with 'acpi_osi=Linux': brightness is low at first, but Fn+brightness allow to increase it successfully. Image is not distorted.
