Hi,
I'm testing kernels 3.7.X vs 3.6.11 on an HP Folio 9470m machine, i915
driver for a VGA compatible controller: Intel Corporation 3rd Gen Core
processor Graphics Controller (rev 09) 8086:0166
With 3.6.11, the brightness can be correctly set using fn+f9/10: kde
shows the bar and brightness changes.
With 3.7.1 kde shows the percentage bar and
/sys/class/backlight/acpi_video0/brightness is updated, but the screen
brightness does not changes.
I fear some mistakes in my .config migration to 3.7 but I can't find
which one, so if someone can shed some light I will be very happy :)
logs, dumps and whatever information is needed available on demand (to
keep this message short)
Thanks for any answer
