Bug Description
Binary package hint: hal
Ubuntu 8.04, today's updates applied.
hal version 0.5.10-5ubuntu8
Once of the recent updates (kernel maybe) broke something and now on my Thinkpad R61i i cannot change LCD brightness. Either power manager, or using brightness applet, or even directly echoing different values to /sys/class/
The only thing i see in dmesg is:
thinkpad_acpi: unknown LID-related HKEY event: 0x5010
My problem is that in 8.04 power consumption was unfortunately increased and with max. LCD brightness I'm still unable to get close to battery operation time I had on Gutsy.

I can confirm this is also the case on the T61. Brightness worked fine until an update within the past couple of days.
