Description Khashayar Naderehvandi 2007-10-01 02:11:24 UTC 
On my lifebook p7010 hal doesn't set or get brightness. I'm trying this under ubuntu 7.10, gutsy gibbon which I believe sports hal 0.5.9.1. The chipset is intel 855GM and using the fn-keys to set brightness (fn-f6 & fn-f7) works just fine.

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!

PS. Not sure which hal component this should be filed under

Please attach output of lshal. What prints: 'grep . /sys/class/backlight/ -r' ?
Comment 3 Khashayar Naderehvandi 2008-01-04 05:45:45 UTC 
'grep . /sys/class/backlight/ -r' returns nothing. In fact 'ls /sys/class/backlight' returns nothing either.

Will attach output of lshal in its completeness.

Is it considered bad manners/pointless to also file this bug downstream at my distribution's bug tracker? I'm only asking because there's not much happening here. I don't want to take up precious dev time with this very low-priority bug, but I'm sure there is more information I could give to help (although I don't know what).

Regards,
K.

If there is no sysfs backlight interface we can't do anything. Report this maybe to the kernel guys. HAL only handle stuff in /sys/class/backlight the common interface for such things. --> NOTOURBUG

I've filed a bug at the linux kernel bugzilla now. However, I'm wondering whether this shouldn't be filed against the intel driver, really? Seems more logical to me...
