minor issue with T41: blue tooth LED is on even if bluetooth support is not compiled into kernel

I observed this with kernel 2.6.26.8 (Gentoo) prior kernel versions instead 
doesn't seem  to switch on that LED.

You dont need to have BT support in the kernel to have the BT device
"on". Is your kernel built with rfkill support, if so, could you load
the rfkill module with the default_state=0 option?

That would do it, yes.  Good catch, Evgeni!  I bet this is the
"problem".

Newest thinkpad-acpi from ibm-acpi.sf.net has code that is supposed to
store the BT rfkill state across reboot and shutdown(!), please try
that and tell me if it works.  It will override the default_state with
whatever state BT rfkill was when you last rebooted/shutdown the
thinkpad.

This actually makes me wonder if I shouldn't add a knob to the rfkill
core to let the user order the rfkill core to *force* all rfkill
switches to block state even if platform drivers like thinkpad-acpi
request a different behaviout...

Keycodes 360 and 372 when using ThinkVantage and Fn+Space on T61

Hi,

I set up X.org on my T61 to use HAL for input device configuration (xorg.conf 
contains no input devices at all).

Everything works fine using the evdev driver 2.0.8 on X.org server 1.5.3 except 
the ThinkVantage and Fn+Space keys report invalid keycodes.

More specifically:
"input-events" & "xev" report nothing, ACPI events get reported by 
"acpi-listen". In Xorg.0.log though, I get the following warnings:

(WW) ThinkPad Extra Buttons: unable to handle keycode 360
(WW) ThinkPad Extra Buttons: unable to handle keycode 372

These warnings are printed only once, the first time I press the respective 
button. I was able to correlate them by checking the acpi-listen output.

So the ThinkVantage button sends ACPI signal ibm/hotkey HKEY 00000080 00001018 
and keycode 360.
The Fn+Space key sends ibm/hotkey HKEY 00000080 00001014 and keycode 372.

Is this a bug of thinkpad_acpi or of the evdev driver? Any ideas how I could 
debug it further? Using the debug_level sysfs property I couldn't get more 
information.

Best regards,
Jens

Ah, at least evdev now warns you when it is screwing things up.  This
is a step forward.

See my comment above.  Maybe it can now even be configured to actually
do something sensible to the KEY_* events above 256, but I wouldn't
know how to do it :(

I gave the git log of the evdev driver a short look and after seeing this commit 
I'm not very confident that it will be able to handle such events anytime soon...

Yup, Julien Cristau just confirmed me on IRC that there was no way for X
get keycode over 255.

Then they will have to come up with some hard hack, maybe using modifiers,
to work around that braindamage.  Because keyboards NEED more than 256 code
points in Linux and anything else doing modern keyboard translation,
nowadays...

There is an enhancement bug report about this which has been opened half and a 
year ago: http://bugs.freedesktop.org/show_bug.cgi?id=11227

Just in case anyone's interested in it.

Jens

crt_enable doesn't work on my T61

Hi list,
    I am using Fedora 9 on my thinkpad T61. Today I try to use an outside LCD monitor, but failed. I try "echo crt_enable > /proc/acpi/ibm/video" but it doesn't work.
I have searched in google and can't find the reason. Help is needed. Thanks.
