regulate backlight on X230 and T430 worksincorrectly

Igor Gnatenko — 2013-04-29T07:45:40

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 ?

Suspend failure on Thinkpad X1 Carbon

Dinyar Rabady — 2013-03-18T20:18:41

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

Re: thinkpad_acpi unhandled HKEY events

Samuel Groß — 2013-03-08T12:24:49

Hi,

I just found another unhandled event: unhandled HKEY event 0x60c0.
Now this one is caused when the laptop is put in tablet mode (turn 
screen around and "close" it) and when the screen is put up again.

For the two 0x60bx events I'm still not sure, I think its also something 
with the screen, they appear right after the 0x60c0 event, but also on 
their own...
I can pretty reliable trigger those when i just tilt the laptop back a 
bit, so the screen is in a different angle. Then usually the 0x60b1 
triggers when I stop tilting and the 0x60b0 is triggered tiwce when I 
then tilt it back to the way it was.
Anything else I should try?

Ciao,
Samuel Groß

unhandled HKEY event

Marcos Dione — 2013-03-28T09:33:36

    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

    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:.

W520 LCD Screen

Zach Day — 2013-03-27T16:42:36

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 onThinkpad E420s

Chris Tolliday — 2013-03-14T09:22:07

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

[PATCH 0/1] thinkpad-acpi: kill hotkey_thread_mutex

Oleg Nesterov — 2013-03-07T17:53:05

Well, there could be another bug. Say, hotkey_poll_stop_sync() can block
on hotkey_thread_mutex if another thread was started. But at first glance
this can't happen (hotkey_mutex), and even _if_ it can this needs another
fix.


IIRC, it always was... But at least currently it is certainly syncronous.
kthread_stop(t) does wait_for_completion(t->vfork_done), complete(vfork_done)
can't happen unless this task calls do_exit().

Hmm. I just noticed that the recent changes in kthread_stop() are not correct...
But this is offtopic and doesn't affect thinkpad_acpi.c, I'll write another
email later.

So, what do you think about (UNTESTED) 1/1 ?

Oleg.

Hi Samuel!

There are two conditions that cause 60b0 and 60b1 events, check whether
they're related to IO ports or docks being plugged/unplugged...

Unfortunately, they're hooked directly to ACPI GPEs (interrupts) and GPIO
lines, so we need to actually find out the hard way what triggers them.

Re: ThinkPad X230 fail on Linux

Henrique de Moraes Holschuh — 2013-02-28T01:32:21

1. thinkpad-acpi doesn´t have anything to do with this problem.

2. check if you have some ethernet power management option set in the
BIOS/EFI configuration

3. if it is not the BIOS/EFI, triple-check to make sure your linux distro is
not messing with the ethernet power saving mode.

Ask around in the linux-thinkpad ML, maybe someone there with a X230 can
help you track down the real reason the NIC is being disabled while on
battery [to save power]
