wacom-gui dies on RHEL 7.6 with a Cintiq Pro 24

[montygreen]

Manually starting wacom-gui produces the following errors:

[root@sulawesi ~]# wacom-gui

Can you please provide me the output from libwacom-list-local-devices --database /usr/local/wacom-gui/data ? I think this might be an issue of libwacom-data not having information for the Express Key Remote, similar to #25 having a naming issue. If it is I'll submit a ticket for them to get it updated.

[tb2097]

Please try the latest release (https://github.com/tb2097/wacom-gui/releases/tag/v0.3.0-rc16), as the Cintiq Pro should still load, hopefully.

I'll upgrade to rc16 to test but here's the database

With rc16 I get 2 popups on login:

1. Device information for "Wacom Express Key Remote" not found.
2. Device information for "Wacom Cintiq Pro 2 24" not found.

When I run wacom-gui manually, I got the same 2 popups and only after I dismissed them, did the script except out:

[root@sulawesi ~]# wacom-gui

Hacks put in place to hopefully fix detection for Cintiq Pro 24 & ExpressKeys. (https://github.com/tb2097/wacom-gui/releases/tag/v0.3.0-rc17). If the hacks work I'll contact libwacom-data to update their config files.

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.
