** 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.
