Bug#512482: acpi-support: brightness control on laptops doesn't work

[Bart Samwel]

Seems like a kernel problem then, you get an increase + decrease button
when you press the increase button! I'll have to reassign this to the
kernel. I don't have time now, I'll do it in the weekend.

Cheers,
Bart

 H. AFAIK there's no special support for Fujitsu Siemens brightness
 in acpi-support, but I'm not sure. Could you run acpi_listen while you
 press the brightness keys and show me the output? I would also like to
 see the syslog output when you press the keys, to see what acpid is
 doing. Can you send me this info?

 Cheers,

Bug#512482: acpi-support: brightness control on laptops doesn't work

[Bart Samwel]

Hi there,

 Brightness control on my Debian Lenny laptop doesn't work. When i press
 button for descresing brightness it works, but when i try to increase
 brightness it become brightly and in next second return to previous
 bright level. My lap is fujitsu siemens esprimo mobile u9200.
 In the end are dmesg, lspci and packages related to acpi-suppoprt. Also
 i want to say, that on my friends laptop (he's got another model, sorry
 i don't remember exactly the model) also brightness control trouble. He
 can control it, but in linux only 10 steps of control, instead 10 in
 windows. His lspci and dmesg also attached.
