Wacom tablets in Ubuntu guide/howto

[Typhon]

One more question and then I'll stop.
If I enter xsetwacom commands individually into terminal I get no errors. On the other hand, if I execute xsetwacom.sh script, I get the following messages:

sh ./.xsetwacom.sh
Unsupported offset into 'Wacom Button Actions' property.
Unsupported offset into 'Wacom Button Actions' property.
Cannot parse keyword '+' at position 1
Cannot parse keyword '-' at position 1
Unsupported offset into 'Wacom Button Actions' property.
Unsupported offset into 'Wacom Button Actions' property.

This is my current xsetwacom.sh for Intuos4:

#!/bin/sh

## stylus = ID ? = "Wacom Intuos4 6x9"
xsetwacom set "Wacom Intuos4 6x9 stylus" Suppress "2"  # data trimmed, 0-100
xsetwacom set "Wacom Intuos4 6x9 stylus" RawSample "10"  # default is 4, 1-100
xsetwacom set "Wacom Intuos4 6x9 stylus" Threshold "27"  # 0-2047
xsetwacom set "Wacom Intuos4 6x9 stylus" PressureCurve "0 0 100 100"

## 0   0 100 100  # linear, the default
## 50   0 100  50  # very firm
## 100 0 100 0  # unbelievably firm

## pad = ID ? = "Wacom Intuos4 6x9 pad"
xsetwacom set "Wacom Intuos4 6x9 pad" Button 2 "key ctrl"
xsetwacom set "Wacom Intuos4 6x9 pad" Button 3 "key alt"
xsetwacom set "Wacom Intuos4 6x9 pad" Button 4 "key shift"
xsetwacom set "Wacom Intuos4 6x9 pad" Button 5 "key tab"

xsetwacom set "Wacom Intuos4 6x9 pad" Button 1 "key space"  # button inside touchring
xsetwacom set "Wacom Intuos4 6x9 pad" AbsWheelUp "- "


xsetwacom set "Wacom Intuos4 6x9 pad" Button 6 "key b"
xsetwacom set "Wacom Intuos4 6x9 pad" Button 7 "key t"
xsetwacom set "Wacom Intuos4 6x9 pad" Button 8 "key c"
xsetwacom set "Wacom Intuos4 6x9 pad" Button 9 "key x"

Two things come to mind.

Have you tried eliminating the white spaces? So "+" amd "-" instead. Does that eliminate the error message?

Also do + and - still work? You may need to use something like "Next" and "Prior" instead.

No luck; still the same. Perhaps those key aren't supported anymore.
Command "xsetwacom list modifiers" gives a list of supported keys (or at least I think it does). There is a huge number of F<number> keys (up to f35). I don't think any keyboard has that many F<number> keys so I suspect they mean something else. Any ideas?

They are suppose to be. I don't think AbsWheel was changed to RelWheel for the Intuos. What version of xf86-input-wacom is the Quantal default?

xsetwacom -V

You can assign unused function keys to other things.

[Typhon]

xsetwacom -V
0.17.0

AbsWheel is still AbsWheel according to The Linux Wacom Project website. AbsWUp is now AbsWheelUp and AbsWDn is AbsWheelDown.

There were a few of commits relating to keysyms and wheel events after 0.17.0 came out. 0.18.0 just came out. Just not sure it would help address your issue. But if you want you could compile xf86-input-wacom to check. See part II. a) on the BambooPT HOW TO. You'll need to change 0.15.0 to 0.18.0 where you encounter it.

I've a problem on Ubuntu 12.04. My Intuos4 since yesterday started going crazy.
For example on mypaint if I select a brush and then I move away with the pen it acts like I'm not releasing the pen and it starts to move the brush icons. It's not an hardware problem, because on the same computer I've Ubuntu Natty and is working fine.


A second question is about the ratio difference there is between my tablet (16/10) and my monitor. I'm using a dual monitor 1920x1080 (16/9) with twinview on a Nvidia GTX 570.
On KDE4 I know there is a GUI with an option to Force Proportions. But how do I do if I'm using Unity or XFCE?
It's a problem that I have on 12.04 and on Ubuntu Natty. I know that the second one is not anymore supported, but for several reasons I still need to use it.

Hi marcoshamas,

There was a rare update to xserver-xorg-input-wacom (xf86-input-wacom) within the last week or two in 12.04. Wonder if that has anything to do with it? Might want to consider reinstalling it, or the older version, or upgrade it. Also a kernel update came through last day or two.

If the Gnome tablet applet in Unity's System Settings doesn't do it you can use the same method you would use for calibration: http://sourceforge.net/apps/mediawik...le=Calibration But instead you would find the coordinates for the correct aspect ration and use them. You will lose some active area off the tablet.

Thanks it worked! I took the coordinates from KDE and so on a 1920x1080 with an intuos4 this is what I use:
xsetwacom set "Wacom Intuos4 6x9 stylus" Area 70 65 44704 25146
xsetwacom set "Wacom Intuos4 6x9 eraser" Area 70 65 44704 25146

About the problem I had with the tablet going crazy I was wrong. It was happening also in Ubuntu Natty. But now I know what is the cause. Yesterday I tried this nib for the first time:

Re-inserting the previous nib the pen started to work correctly.

[Favux]

Good job. Nice of the KDE app. to save you from doing some ratios.

How 'bout that. Nice catch on the nib. Was that suppose to be a replacement nib for your Intuos4 stylus? Couldn't tell from the jpg.
