Device information not found

Plugged in my old Wacom tablet, an Intuos "pen & touch small" (CTH-480) as I need to do some graphics stuff over the next few days.

Trying out Wacom GUI (wacom-gui v0.3.0-rc17 rpm download) just displays a error box twice:

... then a mostly blank window:

The console output (as this was launched manually from the cli) shows:

$ /usr/local/bin/wacom-gui
invalid literal for float(): 2,10.5
invalid literal for float(): 2,10.5

The problem sounds a lot like what's described in a comment on https://github.com/tb2097/wacom-gui/issues/26#issuecomment-461136753.

For reference:

$ xsetwacom list
Wacom Intuos PT S Pad pad               id: 9   type: PAD       
Wacom Intuos PT S Pen stylus            id: 10  type: STYLUS

Note that getting Wacom GUI working isn't critical to me. Just tried it more from curiosity than anything else. I was able to switch the tablet to Relative mode (instead of the default Absolute) using xsetwacom, which should be "good enough" for the task at hand. :smile:

$ xsetwacom --set "Wacom Intuos PT S Pen stylus" mode Relative

If you update the file /usr/local/wacom-gui/data/intuos-s-pt.tablet, you should be able to make it work.

- Name=Intuos Pen & Touch Small
+ Name=Wacom Intuos PT S```

If that works, I can just submit another support ticket for libwacom :)

Interesting. That does help, as the two warning dialogs no longer appear, and some of the graphics load. :smile:

It doesn't look 100% correct though, as some errors are displayed on the console (launching this via CLI) as I click on the various buttons. eg Functions, Stylus, Touch:

This appears to be an issue with parsing out the SVG file for the tablet; when I get a moment I'll try and discern if it's an issue with the script or the format of the SVG itself.

No worries @tb2097. I'm happy to run suggested commands and/or poke at stuff if you need. :smile:

Please try using the latest release: https://github.com/tb2097/wacom-gui/releases/tag/v0.3.0-rc18, let me know if this resolves the issue.
