** Description changed:

  Reported by pescadou999 on the ubuntu-fr forum ( http://forum.ubuntu-
  fr.org/viewtopic.php?pid=10790101#p10790101 ).
  
- Acer Aspire 5736z needs nomodeset on 12.04 (with 3.5.0-13-generic from
- xorg-edgers PPA). It wasn't required in 10.04.
+ Acer Aspire 5736z
+ There was no problem with default settings in 10.04.
  
- Alternative: instead of 'nomodeset', the 'acpi_osi=Linux' option can be
- used (but one needs to press Fn+brightness if brightness is too low).
+ 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.
