Going to update my bug report to reflect this. Now the only problem is = I have both acpi_video0 and intel_backlight, and GNOME Power Manager uses the former rather than the latter. Manually setting the brightness through the intel_backlight interface works. Thanks, everyone. --=20 Michel On 07/04/2011 10:57 AM, Zhang Rui wrote: > Hi, Michael, >=20 > please check if the two patches attached help. >=20 > thanks, > rui >=20 > On Mon, 2011-07-04 at 16:48 +0800, Michel Alexandre Salim wrote: >> On 07/04/2011 10:46 AM, Michel Alexandre Salim wrote: >>> Here are the ectool dumps, before setting any brightness (backlight= =3D0), >>> after setting it to 5, and after setting it to 3, plus the typescri= pt >>> log of the commands issued and the sysfs readings. >>> >>> I then set brightness back to 0 (ec-after3.txt) -- didn't log the >>> keyboard interactions because it's the same (value for brightness >>> concurs with what is set, but actual_brightness is still -1) >>> >>> Let me know if you need anything else.
