Unsupported brightness interfase

Hello,

I've got a problem with my Debian Jessie. It doesn't start the UI and while the startup it says:
"Unsupported brightness interface, please contact ibm-acpi-devel-5NWGOfrQmneRv+LV9MX5ug@public.gmane.orge.net"

Some logs are attatched.

Yours sincerely

[PATCH 0/1] thinkpad-acpi: Reduce screen brightness user visible noise.

(This is is a manual follow-up to thread
https://www.mail-archive.com/ibm-acpi-devel%40lists.sourceforge.net/msg03484.html
as I've just subscribed myself to this list and don't have a proper
MUA to reply appropriately.)

I've implemented what I understand from Henrique description of
suggested changes to logging so to reduce noise during boot (and on
this list.)

Please feel free to correct/ask for changes.

Regards,

Recent update breaks Ubuntu on Lenovo X1 Carbon

I recently bought the Lenoxo X1 Carbon and installed Ubuntu 14.04 on it. It's been working relatively smoothly so far, but I just installed the latest updates, and now I'm having trouble starting up. The first time I tried to start it up after reboots, I got the attached screen (which is why I'm writing this).

Also, previously I was able to just choose Ubuntu in the selection screen when starting up and it'd have no trouble. Now the only way I can start it up is by going to the fault tolerance mode, and by resuming the normal startup from there, which works for some weird reason. I'm not sure if this is related.

unsupported brightness API on thinkpad

Hi,

I just updated to the latest version of ubuntu, and had a failure
message during system restart. The message asked that I contact this
email. It claims that the brightness settings are unsupported (code
1529448 thinkpad_acpi).

I have an X1 Carbon Thinkpad with i7-5600U CPU with Intel HD Graphics
5500. The error occurs when I run
Linux version 3.16.0-36-generic

All is OK when I am using Linux version 3.16.0-34

Please let me know if you need any additional information.

Kind regards,

Sven

PS: Just moved back to Ubuntu after five years with MacOS, and I am
loving it!

Got an unsupported brightness acpi

This was working previously, was working during the netboot install, is no longer working. Fixes online didn't. I'm going to try a few more things, but this is about all the useful stuff I'm aware that I should provide, let me know if you need more.

Thinkpad Helix 2nd Generation Convertible Laptop: unhandled HKEY event 0x4012 and 0x4013

Hi all,

I'm getting the syslog messages below. Hardware is Thinkpad Helix 2nd
Generation Convertible Laptop (Type 20CG, 20CH) with ThinkPad Ultrabook
Pro Keyboard (Part Number:4X30G93893).

Context for message is docking and undocking the hardware keyboard with
the slate/tablet. So I'm *guessing* these events are related to the
linux equivalent of either the Windows "GPIO Laptop or Slate Indicator
Driver" or the "GPIO Dock Mode Indicator Driver"

thinkpad_acpi: unhandled HKEY event 0x4012	(keyboard dock event ->
laptop mode)

thinkpad_acpi: unhandled HKEY event 0x4013	(keyboard undock event ->
slate mode)

Please let me know if further information is needed.

Cheers,
John
