Again, this is a machine that have EC firmware problem to handle the brightness level. If the EC firmware works fine, then don't need add acpi_osi=Linux:
To verify it we might need to install Windows (better be Windows 7) on it and see if brightness works. But It's not worth for doing it IMO. :)
Install Windows might not be work, because we need Acer's windows 7 preload image, not just install a standard windows 7. At least download the Windows 7 video driver from acer website and install it. Then compare the brightness control function before acer's driver installed and after. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
