SubjectRe: [Bug #12705] X200: Brightness broken since 2.6.29-rc4-58-g4c098bc

My display *is* at full brightness, but I cannot adjust it,
because I'm missing some files:

[12:35] ikn:~# ls /sys/class/video_output
[12:35] ikn:~# ls /sys/class/backlight
[12:35] ikn:~# ls /proc/acpi
ac_adapter debug_layer embedded_controller fan power_resource thermal_zone
battery debug_level event ibm processor wakeup
button dsdt fadt info sleep

So I cannot adjust brightness. I saw that
/proc/acpi/video/VID/LCD0/brightness was not existing on 2.6.30-rc2-00195-g9f76208

Bug or am I missing some new file location?


Think about Free and Open Source Software (FOSS).
