Info and help for HP TX2500 Series

No, buttons not work. Also i fown what loading with _OS and _OSI "Windows 2006" turn off remoute on my tablet.

Ok. Try adding acpi_osi="!Windows 2006".
! means "not", i.e. you are NOT booting "windows 2006" (Vista).
Simple as that. No decompiling of DSDT needed.

I know what mean "!". Adding you osi var not work, did you know?

However now you have thermal and everything else that you need.
Again, there is no need to do DSDT-decompiling/compiling.

How good for you that you understand !. Shame that you don't understand that you're not the only one reading on this forum and that posts are rarely read by one single person.
But now perhaps you do...

Sorry - about thermal i did not know. But buttons? It's just one why i decompile dsdt (for search how it mapped to system)

Hi Red_Lion,

Please don't overreact to some "constructive" criticism.

Looking for the bezel buttons in the DSDT, or at least trying to find where they are mapping their signal, seems perfectly reasonable. It makes as much or more sense than things I have tried.

Right now my suspicion is the signal is directed to the HP-WMI kernel module. MisteR2 discovered that's where the swivel hinge signal was going. He persuaded Matthew Garrett to seperate the signal out of the docking event and provide a patch. We almost have auto-magic rotation now. See Recent News towards the bottom here: http://ubuntuforums.org/showthread.php?p=6274392

Please take a look. We still haven't quite figured it out. Running a script isn't quite auto-magic.

[Red_Lion]

Hehe... I try to fix this with no patching.
It's runnig under user:

#!/bin/bash

old="0"
while true; do
	if [[ -e /sys/devices/platform/hp-wmi/dock ]]; then
		new=`cat /sys/devices/platform/hp-wmi/dock`
		if [[ $new != $old ]]; then
			if [[ $new == "0" ]]; then
				echo "Rotate to normal, hide cellwriter"
				xrandr -o normal 
				xsetwacom set stylus rotate NONE 
				xsetwacom set touch rotate NONE 
				xsetwacom set eraser rotate NONE
				cellwriter --hide-window
			elif [[ $new == "4" ]]; then
				echo "Rotate to tablet, show cellwriter"
				xrandr -o right 
				xsetwacom set stylus rotate CW 
				xsetwacom set touch rotate CW 
				xsetwacom set eraser rotate CW
				cellwriter --show-window
			fi 
		fi
		old=$new
		sleep 1s
	fi
done

Also this make work remoute/bezel buttons in tablet mode (need run under root)

#!/bin/bash

old="0"
while true; do
	if [[ -e /sys/devices/platform/hp-wmi/dock ]]; then
		new=`cat /sys/devices/platform/hp-wmi/dock`
		if [[ $new != $old ]]; then
			echo -n "i8042" > /sys/bus/platform/drivers/i8042/unbind
			echo -n "i8042" > /sys/bus/platform/drivers/i8042/bind
		fi
		old=$new
		sleep 1s
	fi
done

Also (if we go back to DSDT) look to this:

                    Method (_Q16, 0, NotSerialized)
                    {
                        Store ("!!! DVD/Music Button pressed !!!", Debug)
                        Store (QBBB, Local0)
                        If (LEqual (Local0, 0x03))
                        {
                            Notify (MBTN, 0x02)
                        }

                        If (LEqual (Local0, 0x06))
                        {
                            Notify (PBTN, 0x02)
                        }

                        If (LEqual (Local0, 0x09))
                        {
                            Notify (VBTN, 0x02)
                        }

                        If (LEqual (Local0, 0x12))
                        {
                            Notify (TBTN, 0x02)
                        }

                        Store (0x04, ^^^^WMID.WEID)
                        Store (Zero, ^^^^WMID.WEDT)
                        Notify (WMID, 0x80)
                    }

If you see "Method (GBBV, 0, NotSerialized)" (i will find this by QBBB) you will see what all events listed in _Q16 not present in GBBV (it's hp_wmi?)

Hi Red_Lion,

Right, that's my guess, HP-WMI.

Are you are saying this works for you?:

#!/bin/bash

old="0"
while true; do
	if [[ -e /sys/devices/platform/hp-wmi/dock ]]; then
		new=`cat /sys/devices/platform/hp-wmi/dock`
		if [[ $new != $old ]]; then
			if [[ $new == "0" ]]; then
				echo "Rotate to landscape"
				xrandr -o normal 
				xsetwacom set stylus rotate NONE 
				xsetwacom set touch rotate NONE 
				xsetwacom set eraser rotate NONE
			elif [[ $new == "4" ]]; then
				echo "Rotate to portrait"
				xrandr -o right 
				xsetwacom set stylus rotate CW 
				xsetwacom set touch rotate CW 
				xsetwacom set eraser rotate CW
			fi 
		fi
		old=$new
		sleep 1s
	fi
done

It gives you auto-magic rotation? How exactly are you setting it up under "user"?

Are you on Jaunty (9.04)?

[Red_Lion]

On non patched hp_wmi - work.

Need run under user in xorg (just save, +x, and put in in autostart in gnome/kde/xfce...).

If you rotate screen to tablet mode - this script rotate stilys/eraser (but see - here is no touch - i broken him, so not put in to script by hands) to left-handed and show cellwriter. If you in normal "notebook" mode - normal rotation and autohide cellwriter (in mode change only).

Just run on non patchen hp_wmi - you will see

If i not mistake it's you call "magic rotation"?

// Also - i on archlinux This script was also tested on 8.10, 9.04

Hi Red_Lion,

You must be using Kubuntu Jaunty (9.04).

I understand you now. You are using the unpatched HP-WMI and using the "docking event" as the trigger. Clever.

Unfortunately that won't work for Intrepid (or Hardy) because there is no HP-WMI.

$ lsmod
wmi                    15808  0
dock                   18592  1 libata

~$ modinfo -d wmi
ACPI-WMI Mapping Driver

$ modinfo -d dock
ACPI Dock Station Driver

So there is no "hp-wmi/dock" in "/sys/devices/platform/". Instead there is "/sys/module/wmi", "/sys/bus/acpi/drivers/wmi", and "/sys/module/dock". Oh well.

[Red_Lion]

Ohh... About 8.10 - sorry - i think what anover ubuntu user who use this script is on 8.10.

I know what a say now is naive (i don't know can be compiled on 8.10) - but try to compile and install hp_wmi in my attachment.
