regulate backlight on X230 and T430 works incorrectly

Hi developers!
In my ThinkPad X230 and ThinkPad T430 regulate backlight works
incorrectly.
I test with xrandr all value, but some value not working. I attach
LogFile with test results.
This problem present since kernel 3.5 or 3.6.
Before max_backlight = 15. After = 100.
In other devices (IdeaPad Z580, Acer 5220, etc.) works correct.
What component has bug ?

Igor Gnatenko

Suspend failure on Thinkpad X1 Carbon

Hi,

I just removed my laptop from my backpack and noticed that it failed to suspend. I found this email address in dmesg.

This occurred on an up-to-date Fedora 18 system.

$ uname -a

Linux dinyar-x1c 3.7.9-201.fc18.x86_64 #1 SMP Mon Feb 18 21:07:56 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

I have attached the output of dmesg as well as /var/log/messages. I've also attached /var/log/pm-suspend, but I'm not entirely sure whether that's relevant. (pm-powersave is empty in case it is relevant.. )

Best,

Dinyar

unhandled HKEY event


    I have a Lenovo Thinkpad T430 that I bought in october last year
running Debian Sid with kernel 3.6.9 from experimental. I needed this
kernel version because some things do not work (sorry, I can; t remember
what exactly) wit the current Sid's kernel, 3.2.39. 

    yestarday I tried to suspend it and it didn't. by chance I checked
dmesg and I found this:

[2107312.486760] thinkpad_acpi: unknown possible thermal alarm or keyboard event received
[2107312.486767] thinkpad_acpi: unhandled HKEY event 0x6040

[2107312.487224] thinkpad_acpi: EC reports that Thermal Table has changed

    I successfully managed to suspend the machine via pm-suspend, so
it's no blocker.

    I'm not subscribed to the list, so I added myself to the CC:.

unhandled HKEY event

Heya,

I just got this while compiling a kernel:

Before that happened, my temperature was at 96 degC constantly and the
CPU sometimes throttled down from 2.7GHz to 1.8 or so. After this, I'm
on 62 degC (so there should be room), but my CPU stays on 800 MHz.

W520 LCD Screen

I have a Thinkpad W520 with the colorimeter on it. To use the colorimeter, you start the calibration program, close the lid, and let it run. Normally, when closing the lid, the display automatically shuts off. The normal windows driver manages to turn off this feature while calibrating, but I can't seem to find anyone that's been able to duplicate this under Linux. I was wondering if anyone could offer insight on how to accomplish this.

Thank you,

- Zach Day

thinkpad_acpi: unhandled HKEY event 0x6050 on Thinkpad E420s

Hi,
I'm reporting some dmesg errors that occur on wakeup on my thinkpad.

This occurs everytime I suspend and wake the laptop, by closing and
opening the lid, or by manually suspending and waking by pressing
enter

Every time after wake up the screen is so dark it looks almost like it
is off, I have to press a brightness up or down key (Fn+F7 or Fn+F8)
for brightness to return to normal and see the screen.

Attached are two example dmesg outputs, first one using the lid,
second one using suspend from menu, seems the same

I'm running Ubuntu 12.10 and kernel 3.8.2

Thanks,
Chris Tolliday
