Wacom DigitizerII 12x18 UD1218R Problems with Maverick Server

[dreh]

Hi,
i'm having trouble with my Wacom tablet. Its attached over serial cable. I used this tutorial http://ubuntuforums.org/showpost.php...12&postcount=1 .

wacdump /dev/ttyS0 sees the tablet and values are changing drawing on it:
MODEL=Wacom DigitizerII 12x18 ROM=1.4-2
CLS=Serial VNDR=Wacom DEV=Digitizer II SUB=UD-1218-R
A0 51 5E 04 59 1C 00 25 08 .Q^.Y..%.
TOOLTYPE=PEN IN_PROX=in

/usr/share/X11/xorg.conf.d/50-wacom.conf
Section "InputClass"
Identifier "Wacom serial class"
MatchProduct "Serial Wacom Tablet"
Option "Device" "/dev/ttyS0" # SERIAL ONLY
Driver "wacom"
Option "ForceDevice" "ISDV4"
EndSection

Do I need the server section as described in http://linuxwacom.sourceforge.net/in...owto/srvlayout?

Tried several different settings the mileage is between GDM ist starting up, keyboard and mouse is dead, ... every approach never brought up the tablet.

xserver-xorg-input-wacom 10.8-ubuntu is installed
xserver 1.9
uname -r 2.6.35-23-server

Hi dreh,

Welcome to Ubuntu forums!

It's not the "ServerLayout". See "Notice for Serial Graphics Tablet Users" in red near the top of the HOW TO you linked. It links to the patches and instructions you need.

The serial patches only work up to and including xf86-input-wacom 0.10.6. As you see thorwil figured out how to get the patched 0.10.6 to compile in Maverick, overcoming the last obstacle.

Meanwhile we hope someone will take up developing the serial patch further. Peter gave big hints and pointers as to what he would accept into xf86-input-wacom.

Good luck!

Hi Favux,
ty for your warm welcome and your fast answer.
I tried the tutorial again. I can't get it run. This is what I did:

1. uninstalled xserver-xorg-input-wacom via synaptic
2. sudo rmmod wacom
3. git clone git://linuxwacom.git.sourceforge.net/gitroot/linuxwacom/xf86-input-wacom. As far as I understood the patch is already integraded in wcmCommon.c. or am I wrong?
4. ./autogen.sh --prefix=/usr
5. make & sudo make install
6. ./autogen.sh --prefix=/usr --libdir=/usr/lib64 I did this cause I have evdev_drv.so in both locations - just to be sure + make make install
7. gksudo gedit /usr/share/X11/xorg.conf.d/50-wacom.conf
Section "InputDevice"
Driver "wacom"
Identifier "stylus"
Option "Device" "/dev/ttyS0"
Option "Type" "stylus"
Option "ForceDevice" "ISDV4"
EndSection

Is this right: The wacom.ko is not necessary for serial tablets? So I can ignore it?

Which Syntax is the right one or what is the difference between Section "InputDevice" and Section "InputClass".

The tutorial is a bit complicated, (English is not my mother language), so could you point me the right direction.
Ty for your help !

Hi dreh,

1. uninstalled xserver-xorg-input-wacom via synaptic

Don't, there is a new dependency xserver-xorg-input-all which will also be uninstalled and you need it installed. It's necessary. So reinstall.

3. git clone git://linuxwacom.git.sourceforge.net/gitroot/linuxwacom/xf86-input-wacom. As far as I understood the patch is already integraded in wcmCommon.c. or am I wrong?

The patch is not in xf86-input-wacom 0.10.10+. Peter declined to accept it, it needed more work. He gave a long, detailed critique/guideline of what was needed after the second patch attempt. The guy working on it stopped after his second attempt. Other things to do I guess. The second patch (the improved version) will only work on 0.10.6. So you have to download the tar: http://linuxwacom.sourceforge.net/ (all packages). Patch it. Then you have to do the patch so 0.10.6 will compile in Maverick.

4. ./autogen.sh --prefix=/usr

With the tar it'll be:

./configure --prefix=/usr

I don't know about the 64-bit flag on your system.

Option "ForceDevice" "ISDV4"

Remove, it's for tablet pc's. In fact in the recent versions of xf86 it's been deprecated for them too. If anything you'd need something like:

Option "ForceDevice" "Serial"

So it should look something like:

Section "InputClass"
    Identifier "Wacom serial tablet class"
    MatchDevicePath "/dev/ttyS0"
    Driver "wacom"
#    Option "ForceDevice" "Serial"  # ?
EndSection

"InputClass" is for .conf files. We'd have to see if there were any other matches we could do.

Is this right: The wacom.ko is not necessary for serial tablets? So I can ignore it?

Yes, the wacom.ko is the usb kernel driver. Your serial tablet does not need it.

Any clues why it's not working. I tested different Baud Rate didn't change anything. The module says its version 0.10.8 shouldn't it say 0.10.6 (patched driver)?

Good, progress!

This would be a serial snippet for 50-wacom.conf in /usr/share/X11/xorg.conf.d/. I thought you were going to use it. If you are using xorg.conf you don't need to worry about it. I don't think any of the serial snippets will match your tablet so you don't have to deactivate them. You want to use either xorg.conf or 50-wacom.conf. Not both. So remove it from xorg.conf.

Section "InputClass"
    Identifier "Wacom serial tablet class"
    MatchDevicePath "/dev/ttyS0"
    Driver "wacom"
    Option "ForceDevice" "Serial"  # ?
EndSection

Also starting with X server 1.7 "SendCoreEvents" is deprecated (no longer used). And unless you have a Wacom tablet mouse you do not need the cursor section. So it would look something like:

Section "ServerLayout"
  Identifier    "Default Layout"
##  Screen        "Default Screen"0.10.
  InputDevice   "stylus"
  InputDevice   "eraser"
EndSection

Section "InputDevice"
  Driver        "wacom"
  Identifier    "stylus"
  Option        "Device"        "/dev/ttyS0"      # SERIAL ONLY
  Option        "Type"          "stylus"
  Option        "ForceDevice"   "SERIAL"           # Tablet PC ONLY
  Option	"BaudRate"	"38400"
EndSection

Section "InputDevice"
  Driver        "wacom"
  Identifier    "eraser"
  Option        "Device"        "/dev/input/wacom"0.10.
  Option        "Device"        "/dev/ttyS0"      # SERIAL ONLY
  Option        "Type"          "eraser"
  Option        "ForceDevice"   "SERIAL"           # Tablet PC ONLY
  Option        "BaudRate"      "38400"
EndSection

Do you know what the baudrate of the tablet is suppose to be? I vaguely remember reading the old serial code. I think the allowed baudrates were 2400, 4800, 9600, 14,400 ? and ? I guess I don't remember for sure. Also try without the Option:

  Option        "ForceDevice"   "SERIAL"

The module says its version 0.10.8 shouldn't it say 0.10.6 (patched driver)?

That worries me too. Maybe something new to 0.10.8 that 0.10.6 didn't over write? I don't think thorwil mentioned it.

[dreh]

Ok I found out the patched driver was installed in the old place.

/usr/local/lib/xorg/modules/input/

instead of

usr/lib/xorg/modules/input/

now xorg is loading the proper 10.6 (patched)
Module wacom: vendor="X.Org Foundation"

[ 4477.981] ABI class: X.Org XInput driver, version 11.0

for some reason /usr/share/X11/xorg.conf gets totally ignored so I use /usr/share/X11/xorg.conf.d/50-wacom.conf

Section "ServerLayout"
  Identifier    "Default Layout"

#  Option        "ForceDevice"   "SERIAL"           # Tablet PC ONLY
#  Option       "BaudRate"      "38400"
EndSection

#  Option        "BaudRate"      "38400"
EndSection

if I uncomment the Screen option the Xserver doesn't boot.
Option "ForceDevice" "SERIAL" -> makes no difference
Option "BaudRate" "38400" -> seems like correct speed is detected automatically

Hi Ty dreh,

Looks like excellent progress!

There is some confusion about xorg.conf and 50-wacom.conf. xorg.conf should still be in the old location:

/etc/X11/xorg.conf

Depending on your video chipset driver you may not even have an xorg.conf in /etc/X11 starting with X server 1.7/Lucid (10.04). You may have to create the xorg.conf file.

50-wacom.conf is the new udev configuration file that allows usb hot plugging and is at:

/usr/share/X11/xorg.conf.d/50-wacom.conf

for Maverick.

So you are putting a xorg.conf in the 50-wacom.conf. I am surprised it works! That's why your screen section breaks X. They have different syntax. You can consider the .conf files in xorg.conf.d as extensions of xorg.conf, sort of.

I showed you a serial snippet for 50-wacom.conf and a xorg.conf. Use one or the other. Not both. Not xorg.conf in a 50-wacom.conf. I think I would use the xorg.conf and forget about 50-wacom.conf. A serial tablet isn't hot plugged.

Ok I found out the patched driver was installed in the old place.
/usr/local/lib/xorg/modules/input/

Forgot the flag, right? Good find. You probably should delete the version in the wrong location if you haven't already. Seeing the correct 0.10.6 version is reassuring.

Option "BaudRate" "38400" -> seems like correct speed is detected automatically

Why then is your Xorg.0.log showing?:

[ 4478.185] (**) Option "BaudRate" "9600"
[ 4478.185] (**) stylus: serial speed 9600

xinput list looks good. It is suppose to say [XExtensionKeyboard] if the tablet is on the Wacom driver. That is what you want to see.

Some of the serial tablets have trouble initializing. Some serial tablet pc's log out of X and then back in and that often gets their digitizer working. I have no idea why this works.

I have seen some serial tablets require starting wacdump to initialize. Again no idea why this works. So they use a script to start wacdump when they boot to get their tablet going.
