I think this linux-kamal-backlight PPA is not supported any longer for 10.10
and 11.04.
Kamal suggested to update to 12.04. I've seen backlight controls work
fine under 12.04 without any PPA only after adding kernel parameters.

probably I'm only one who stuck in the past with Maverick 10.10 :) but I love
it!
After updating to a new kernel, I've lost the brightness control:

Can you please update the ppa? Do you think the ppa will be maintained in

probably you should read the patch description carefully. I've changed this:
GRUB_CMDLINE_LINUX_DEFAULT=quiet splash acpi_backlight=vendor
thinkpad_acpi.brightness_enable=0
in /etc/default/grub.
After update it works on my Lenovo Z360.

I could solve this problem by taking the battery out and plugging it back after
a while. The status is detected correctly. Moreover, the battery is charging to
100% now.
I hope it will help!

I have exactly the same issue with crazy fan speed on my Lenovo z360. But if
I remember it right, it started going crazy since I had switched from 10.04 to
10.10 (this patch wasn't installed). I guess it is not related to the
brightness control patch. Correct me if I'm wrong!!!

Before I switched to Linux Ubuntu, I had used Windows where I chose an option
to the case when my battery is charged up to 80% to maximize LIFETIME of the
battery like it is described here:

I have a little bit different problem with the fan speed. When I start
Ubuntu first time (maybe the reason is that the system is cold), my fan
is going crazy. After rebooting two or even three times everything is
going well.
The display-brightness problem influences me deeply as well!!!
