Summary: no sysfs backlight interface on lifebook p7010
Product: ACPI
Version: 2.5
KernelVersion: Any kernel version
Platform: All
OS/Version: Linux
Tree: Mainline
Status: NEW
Severity: normal
Priority: P1
Component: Power-Video
AssignedTo: [EMAIL PROTECTED]
ReportedBy: [EMAIL PROTECTED]
Latest working kernel version:
None
Distribution:
Any (I can perform tests and further debugging on Ubuntu 8.04, or possibly
archlinux)
Hardware Environment:
Fujitsu-Siemens Lifebook p7010, intel 855GM.
Problem Description:
I first filed this bug at freedesktop against hal
(http://bugs.freedesktop.org/show_bug.cgi?id=12638), but the hal guys suggested
I take it over here. Basically, the problem is that hal cannot get/set
backlight on my laptop since there is no sysfs interface to deal with that.
Using Fn-F6/Fn-F7, I can manually change backlight.
lshal | grep panel
returns nothing. I'll attach the output of dmidecode.
Please give me more information on how to debug this issue. Many thanks!
