Subject: Touchscreen on Panasonic CF-18

Hello,
I am having difficulties getting the touchscreen on a Panasonic CF-18 Toughbook \
working in X (Version 7.0.99.903 (7.1.0 RC 3)). I do not know if this is a \
problem at the OS level or with X. This is not the digitizer (Wacom) version of \
the laptop. Kernel 2.6.16.16 reports the following (not necessarily all \
touchscreen related):
PNP: PS/2 Controller [PNP0303:K101,PNP0f13:MOU2] at 0x60,0x64 irq 1,12
i8042.c: Detected active multiplexing controller, rev 1.1.
serio: i8042 AUX0 port at 0x60,0x64 irq 12
serio: i8042 AUX1 port at 0x60,0x64 irq 12
serio: i8042 AUX2 port at 0x60,0x64 irq 12
serio: i8042 AUX3 port at 0x60,0x64 irq 12
serio: i8042 KBD port at 0x60,0x64 irq 1
Serial: 8250/16550 driver $Revision: 1.90 $ 4 ports, IRQ sharing disabled
serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
serial8250: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
00:0b: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A
00:0c: ttyS1 at I/O 0x2f8 (irq = 3) is a 16550A
And later in the boot:
input: PS/2 Generic Mouse as /class/input/input1
input: PS/2 Generic Mouse as /class/input/input2
There is a lot of files created in these /sys entries. I can provide details as \
needed.
/dev/input has the following:
crw------- 1 root root 13, 64 Feb 19 05:19 event0
crw------- 1 root root 13, 65 May 16 18:15 event1
crw------- 1 root root 13, 66 May 16 18:15 event2
crw-rw---- 1 root root 13, 0 Oct 19 2005 js0
crw-rw---- 1 root root 13, 1 Oct 19 2005 js1
crw-rw---- 1 root root 13, 2 Oct 19 2005 js2
crw-rw---- 1 root root 13, 3 Oct 19 2005 js3
crw-r--r-- 1 root root 13, 63 Feb 11 04:26 mice
crw-r--r-- 1 root root 13, 32 May 16 18:15 mouse0
crw-r--r-- 1 root root 13, 33 May 16 18:15 mouse1
crw-rw---- 1 root root 13, 35 Oct 19 2005 mouse3
evtest on event0 shows it is the keyboard. event2 is the built in touchpad. \
Both these generate events like one would expect. evtest event1 (which I \
suspect is the touchscreen) yields:
Input driver version is 1.0.0
Input device ID: bus 0x11 vendor 0x2 product 0x1 version 0x0
Input device name: "PS/2 Generic Mouse"
Supported events:
Event type 0 (Sync)
Event type 1 (Key)
Event code 272 (LeftBtn)
Event code 273 (RightBtn)
Event code 274 (MiddleBtn)
Event type 2 (Relative)
Event code 0 (X)
Event code 1 (Y)
Testing ... (interrupt to exit)
No events are generated when the display is touched.
I have tried the fpit driver (using various xorg.conf/setserial combinations). \
The touchscreen works fine in Windows (reports device as Fujitsu touchscreen).
Any thoughts?
John

He remembered the knowledge. He remembered feeling his mind as cold as ice and
limitless as the night sky. He remembered being summoned into reluctant
existence at the moment the first creature lived, in the certain knowledge that
he would outlive life until the last being in the universe passed to its
reward, when it would be his job, figuratively speaking, to put the chairs on
the tables and turn all the lights off.
He remembered the loneliness.

To me it appears that the device was not recognised correctly. A
touchscreen is an absolute pointer device, and here it shows that it is
recognised as a relative pointer device.

Thanks for the feedback...
I hacked at the kernel source (drivers/input/mouse/lifebook.c) in order
do get the touchscreen seen as a touchscreen by the input system. My
shotgun approach also made the touchpad act like a touchscreen. With
this change, X was able to work with the touchscreen. I tried evtouch,
evdev, fpit and maybe another Driver. They all acted generally the
same. Issues I had maybe were due to lack of calibration.
Maybe someone who knows what they are doing and has an interest in this
could come up with the right solution. I would be willing to give an
implementation a try if someone could pass on the approach needed to
have only one of two built-in pointing devices seen as a specific kind
of pointing device. The lifebook.c code uses DMI information to
determine the model of laptop. More granularity is needed. Maybe there
is a way to take action on something like the "Phys=" entry in
/proc/bus/input/devices.

Hello world
I'm seeking to get in contact with John R who wrote a driver for the
touchscreen of the panasonic CF-18. I have one of these babies and would
enjoy to test his driver on it.
Best regards
Antoine Drouin
