Ok passed the test with flying colors Smile
apart from I used the eventn option in xorg.conf instead of /dev/wacom doh...now that is so slick

groovy

Ok the udev detection is great but I'm trying to do the same with hotplug.
A script to remove the link then create a new one pointing to the correct device....no probs...but how is it launched?
All the info I find relating to hotplug mentions files that do not seem to be in puppy... Somewhere to list the device and name the script to run I believe

PostPosted: Sat 18 Jul 2009, 04:45    Post subject: Can you boil this thread down for me and my HP TC1100?  
I have a little experience with Puppy, having installed this wonderful distro on some old notebooks.

I'd like to try it on my HP TC1100 - I tried to follow this discussion thread to find if there is a PET package here someplace that will install what I need for the digitizer & pen..... is there one in existence? Can someone tell me where to get it?

ALSO: is there any way to get screen rotation to work using the TC1100's built-in rotate screen "button" which is on the frame of the PC?

It seems this thread is relevant to the topic of pen function on TC1100 , but I see a lot of development going on and am not exactly sure where the "product" of all that hard work is to be found.....

Thanks

I don't have one to test with, so I'm not certain I can sort it out, but I'll see what I can do anyway. I see from a post in the Ubuntu forum that it should be doable. But you're going to need the wacom-tools package which I haven't compiled recently, so I'll have to do that first. Hopefully I'll have a guide ready for you by this evening.

Okay, turns out there are precompiled binaries of them included with the source, so I just packaged those. They're at the bottom of the first post in this thread.

Step One: Wacom Driver

You need to go through the first post in this thread and get the wacom driver installed, along with the wacom_tools package.

Additionally, you need to find the "Device" section in /etc/X11/xorg.conf, which begins with:
Code:
Section "Device"

and add these lines:
Code:
Option    "RandRRotation"    "on"
Option     "NvAGP"     "1"
Option    "Button2"    "3"



At this point you should make sure that you're able to draw on the tablet properly. We want to go one step at a time. When the "mouse" is behaving properly, we can move on to the rest. In particular, I think that the Udev rule probably isn't going to work. Jamesbond posted a more complex rule that might help.


Note: any time you run xorgwizard, your /etc/X11/xorg.conf file will be modified. If that happens the above changes to the file will be lost and you'll have to redo them. So I recommend that once you get everythign working, make a copy of the xorg.conf file as 'xorg.conf.WORKS' or something. Don't use the more obvious backup names like 'xorg.conf.bak' because other programs that edit the xorg.conf file might overwrite the backup.




Step Two: A Rotation Script

Next, according to that thread you need a script to rotate the screen when you press the button. One is attached to this post, but I'm also going to show it here since it's short. It's basically the same script that was in the Ubuntu thread, with a couple adjustments to make it work with Puppy. It should be placed in /usr/bin or some other location in the $PATH.
Code:
#!/bin/sh

# Change System Input orientation for Tablet Mode
# Depends on wacom_tools and xrandr

ORIENTATION="$(xrandr | egrep -o 'current [0-9]+ x [0-9]+' | sed 's/current \([0-9]\+\) x \([0-9]\+\)/\1 \2/')"
WIDTH=$(echo "$ORIENTATION" | cut -f 1 -d ' ')
HEIGHT=$(echo "$ORIENTATION" | cut -f 2 -d ' ')
if [  $WIDTH -gt $HEIGHT ]; then
   xrandr -o left
   xsetwacom set stylus Rotate CCW
else
   xrandr -o normal
   xsetwacom set stylus Rotate none
fi

What it does is rotate the screen counter-clockwise if it isn't rotated yet, otherwise it puts it back. It determines the current orientation by looking at the aspect ratio - it makes the assumption that "normal" is wider than it is tall, so users with really funky monitors would need to adjust that part, but it will be fine for you.


Step Three: Finding/Setting the Keysym

Now we need to bind the script to the button, which is a two part process. The command can be bound to a "keysym" very easily. However, first we need to know the keysym of the button you referred to, and if it does not have one we must assign it.


So. To find the keysym (or keycode if there is none) we need the xev program, which Puppy doesn't include by default. It's in the xorg_xorg_full_dri-7.3 package, but that's pretty big (50 megs or so, IIRC). So in case you don't already have that, I've pulled out the xev executable and attached it.

Now that you have xev, use it: Open a terminal and run the command xev. This will open a window with whiteness and a square. Click on the window to make sure it has the focus, and move it to the side so you can see the terminal window too. Now whenever you press or release most keys, it will spout out information. So press the button that you want to control the rotation, and then examine the output. It will look something like this:
Code:
KeyPress event, serial 29, synthetic NO, window 0x2c00001,
    root 0x45, subw 0x0, time 2505691954, (180,42), root:(643,108),
    state 0x2, keycode 65 (keysym 0x20, space), same_screen YES,
    XLookupString gives 1 bytes: (20) " "
    XmbLookupString gives 1 bytes: (20) " "
    XFilterEvent returns: False

KeyRelease event, serial 29, synthetic NO, window 0x2c00001,
    root 0x45, subw 0x0, time 2505692210, (180,42), root:(643,108),
    state 0x2, keycode 65 (keysym 0x20, space), same_screen YES,
    XLookupString gives 1 bytes: (20) " "
    XFilterEvent returns: False

The part you're interested in is the (keysym 0x20, space). As you may have guessed, this output was from my spacebar. Push your button and see if it puts any text there (besides the hexadecimal number - we don't care about that). If it does, that text is the keysym. Note it and skip the rest of this section and go straight to Section Four.


If it doesn't give a keysym, that means you'll need to define one. Not hard. But we need the keycode for that, so now look at the part of the output that looks like this: keycode 65 (it comes just before the keysym section, on the same line). That gives you the decimal number that corresponds to the key. If it doesn't give you one of those (or worse - doesn't even generate an event) then we have a Problem, which will require some research and experimentation to fix... Assuming that it does give you a keycode, we will bind that number (the keycode) to a textual string (the keysym).

To do that you need to create the text file /root/.Xmodmap (if it doesn't already exist). Because the name starts with a '.' it is a hidden file, so you'll need to click on the "eye" icon in the filemanager's toolbar to be able to see it after you create it (or if it already exists). Anyway, open (or create) it and insert the following:
Code:
keycode ??? = XF86Launch0

Except replace the ??? with the keycode you just found. Save the file. Now the next time X starts, it should give the button the keysym 'XF86Launch0'. Use that as the keysym for the next stage.


Step Four: Bind the script to the keysym

Okay, so by this point you should have the wacom driver working, know the keysym for the button, and have the rotatescreen.sh script in the $PATH somewhere (e.g. /usr/bin). Now, assuming you use JWM, edit the file /root/.jwm/jwmrc-personal. This is in the hidden '.jwm' directory, so you'll have to click the "eye" icon in the file manager's toolbar to see it. Okay, now scroll down near the bottom. There should already be some key bindings in there, but whether there are or not is irrelevant. I just want you to put it near them if there already are some, so that things are nice and tidy. Insert the following:
Code:
<Key key="XF86Launch0">exec:rotatescreen.sh</Key>

But replace XF86Launch0 with whatever your keysym is. Make sure you place this somewhere ABOVE the </JWM> line. Save the file.

Now restart X. Hopefully it should all work.


If you don't use JWM then you need to do the equivalent procedure for whatever you do have. Post it and we can help.





FYI, tomorrow night I leave for a week to visit my dad (who also happens to be getting married on Saturday). He doesn't have internet access out there, so please don't think I'm ignoring you if I don't respond right away. I'll get back on Tuesday 28, barring airport-idiocy. Rolling Eyes

If it uses the same kernel as 4.21 and same xorg (7.3) then you may be in look. Look in /lib/modules/ for 2.6.25.16...of it exists if so then hopeful.
Plus it needs the fixed xinput gtk2, or a later proprly compiled version.
As you are being a beta tester be prepared to fix things generally.

I may be being pessimistic Very Happy

Well perhaps try it anyway........if you have no success use an earlier puppy that the packages here do work on

4.3 probably includes whatever the latest version of the kernel driver was at the time that that version of the kernel was released. So unless you use a newer tablet, that kernel driver should be sufficient, and you'd just need to install the xorg driver and then do the configuration. Unless it uses a different version of Xorg, that probably won't be a problem.

I am trying to get my Wacom Bamboo working on Puppy 421 frugal install on harddisk.

I have added the bits to the xorg.conf file but I added them above the line which says that it will be overwritten (hoping to avoid changing this file) each time xorg is run.

Is this OK?

I assume not because my bamboo is working as a mouse but it does not move proportionately up the screen, it does a 1:1 conversion - 1inch on Bamboo = 1 inch on screen, so after about 5 inches, I have run out of Bamboo area!!

Also, the stylus has to be placed on the pad so lightly. I am always 'clicking' on things that I dont mean to, which is a real pain. I have replaced the /dev/input/wacom with /dev/input/event5 to see if that will help, but it does not.

Any ideas what I can try please?

in xerrs.log I have this which is ambiguous - is there an error or not as it says 'success'?

(EE) xf86OpenSerial: Cannot open device /dev/input/event5
No such file or directory.
Error opening /dev/input/event5 : Success

dmesg shows this which suggests an error somewhere.

wacom: no version for "struct_module" found: kernel tainted.
input: Wacom Bamboo as /devices/pci0000:00/0000:00:10.1/usb2/2-1/2-1:1.0/input/input5
usbcore: registered new interface driver wacom
/tmp/ff/linuxwacom-0.8.2-2/src/2.6.24/wacom_sys.c: v1.46-pc0.4:USB Wacom Graphire and Wacom Intuos tablet driver

I'm not sure about the placement. Xorg itself never looks at the comments, so as long as everything is still in the right sections, Xorg will be happy. I have no idea if placing things above that line will actually impact whether they get overwritten by xorgwizard. I've never tried that.

As for the behavior of your stylus, that is erroneous. Normally you can move the pointer around without even touching the pad with the stylus. What you're experiencing is what happens when the xorg.conf file points at the wrong event node. Try using just /dev/ rather than /dev/input/. That might be where the problem is. On the system I'm using right now, I'm using /dev/wacom which is a link to /dev/event9. (So perhaps my documentation on the first post is a little bit off, because that does mention /dev/input/event*.)


Did you use the generic X driver package, or the one that also includes your kernel driver? Might be worth trying the kernel-driver one if you didn't already, as they may have fixed some bugs.

Sometimes when working with drivers it takes a reboot to get everything synced up. Generally that's not needed, but it wouldn't hurt to try (put it back to using the wacom symlink before rebooting, in case the event node changes).

Changing to /dev/wacom seems to have fixed it. Thank you very much for your help.

Pizzasgood ... since you have done such a good job here how about you remove the (hopefully) from the thread title? Smile
