Re: thinkpad_acpi: Add KEY_CAMERA (Fn-F6).

Yes.
	I actually sent the support to udev for the USB keyboard

	I have it and love it, why made sure has support in udev. Works great
in Ubuntu 10.04 (I'm biased of course). But any newer distro should pull
in the udev rules soon (if they havn't already).

Thank your for that. Indeed I
have /lib/udev/keymaps/lenovo-thinkpad-usb-keyboard-trackpoint.

That's good to know.

Ok, that's easy enough to do. I'll rework and send that.

Thinkpad L412

Hi,

I have a Thinkpad L412 not yet supported by thinkpad_acpi, the crucial kernel 
messages (I think) are:

thinkpad_acpi: drv_acpi_handle_init: trying to locate ACPI handle for ec
thinkpad_acpi: drv_acpi_handle_init: ACPI handle for ec not found
thinkpad_acpi: Not yet supported ThinkPad detected!
thinkpad_acpi: thinkpad_acpi_module_exit: finished subdriver exit path...

acpidump, dmidecode output attached.

Can this notebook be supported by thinkpad_acpi? (What would I have to add to 
the driver to get it past this stage at least and try out further?)

Best regards
Helge

Afaik L4xx thinkpads are not real thinkpads but Lenovo SL boxes. There's
a sl-acpi or something driver which is supposed to be in developpment.

x100e wireless disabling (no rfkill interface)

Hi,

I have Thinkpad x100e and using Ubuntu 10.04.

Everything working well. Only problem with wireless rfkill interface.
There is no rfkill interface for wireless card. (present for bluetooth)
I want to disable wireless sometimes.

ibm_acpi driver patched for x100e and installed.

There are rfkill code in rtl8192se wireless source code.
Problem may be related with ibm_acpi driver?

What i sould send about machine?

Waiting for your directives.

Thanks from now...

Second screen on W700ds

Hi I received this message on dmesg while I was opening the secondary
display on W700ds laptop

[ 9738.529133] thinkpad_acpi: unhandled HKEY event 0x5030
[ 9738.529138] thinkpad_acpi: please report the conditions when this
event happened to ibm-acpi-devel@...

A while later when closing it I got the same one (it looks like togle switch):

[ 9754.804131] thinkpad_acpi: unhandled HKEY event 0x5030
[ 9754.804135] thinkpad_acpi: please report the conditions when this
event happened to ibm-acpi-devel@...

I'm using GNU / Linux Debian 5 (stable) and with amd64 kernel from
back-ports (because of Intel 5300 support)

Linux w700ds 2.6.32-bpo.3-amd64 #1 SMP Mon Mar 15 13:49:35 UTC 2010
x86_64 GNU/Linux

When I got Xorg to use the secondary display it was always ON, when
using windows is turned off till you open it and then when you close
it it turns off, now it's on always so sometimes get window to the
second display even when it closed, so If it could be turned off it
much better for usability and power and everything ....

I don't know what you need to know, the acpi-support is version 0.109-11.

Could be somebody so kind and helped me to get this working? Thank you
in advance.
Anton

Re: Second screen on W700ds

Heya,

I am no expert here but you can try switching it off with xrandr, that should 
be just fine if it reacts like a normal screen (no driving output -> standby)

To have it work with pulling the display in and out I guess acpi needs to 
switch on and off the screen, the kernel/xorg stack should handle hotplug 
itself then.

Regards,
Karsten

Re: Second screen on W700ds

Ah, I forgot it's NVIDIA, looks like their driver doesn't do proper xrandr, 
but they ship their own tool, nvidia-settings I think, it's a GUI and should 
be able to switch on and off the seperate screen, it's basicly nvidias xrandr 
(with less power =) )

Karsten

btw, please reply all so it will go back to the list as well

Re: thinkpad_acpi: Add KEY_CAMERA (Fn-F6).

Henrique,
	This patch didn't make your merge request?  Any reason why? Here is a
picture of the T410 keyboard:
