Wacom pen&tablet, multimonitor, plasma 6 and Wayland: usable together?

A little update.
After some time passed and some updates I’ve checked again the graphic pen settings with Wayland and now I have a little change but it still doesn’t work like it should be.
Now, trying to map the portion of the tablet area, I have this

As you can see it seems that it’s reading the whole tablet area.
The issue is that I can’t resize it.
I can resize just the monitors area.

What libinput version do you have?

Sorry but how could I check this?
Where should I see this information?

Thanks in advance.

I’ve searched some info on the web about how to check the library version and it should be done with dpkg.
So I’ve tried and I got this message
immagine

In English it should be something like

dpg-query: the package “libinput” is not installed and it’s any information is available.
Use “dpkg --info” (= “dpkg-deb --info”) to examine the archives.

So, if I used the right command to check the library version, it seems that the libinput library is not installed. Am I right?

I’ve tried a Live version of Fedora 42 Plasma Desktop and it seems that I can change the tablet area in the settings.
So, now, I think that something is not set correctly in my system.
First of all, sorry to bother you but, trying to reply to your question, how can I check what version of libinput is installed?

I’ve installed the libinput-tools and I can see that Wacom is recognised as pen and tablet. In my opinion there is a config file corrupted or not correctly set but I don’t really know how to fix this.
Any tips?

Thank in advance.

If you think you have a config issue, try with a newly created user. If it works with a new user it points to a config issue.

I don’t have access to my pc this week, so apologies if I am not able to help.

As for the libinput version, you find instructions on the libinput homepage. I think typing libinput --version in the terminal might work

Thank you for the suggestion..I hadn’t thought about this.
I’ve tried but it does the same. I can’t see the resize controller for the tablet area, for the screen yes..for tablet no…I can use just the full area.
So it should be something else.

Oh..don’t worry…if you can and when you can it will be more than great…if you can’t, don’t want or anything else..don’t worry… I’ve a working setting with X11 but as X11 will be less and less supported by KDE devs, I’d like to switch to Wayland, but I’d like to use my graphic pen as its best, at the moment I can’t.

libinput --version seems worked and the result is 1.26.2

I am afraid resizing the tablet area requires libinput 1.27

See:

I see… now things become more clear…
…but now I can’t find a way to update it.
I’ve tried with “apt-get install libinput” but it gives me an error message “Impossible to find the package libinput” and I’ve found just the building instruction on the libinput official website.
Searching on the web it seems that I should wait the “rebase” of KDE Neon to a newer Ubuntu version (25.04) . Am I right?

oh oh….
today I’ve updated through Discover and now I can resize the tablet area and match this area with the full resolution of both monitors using Wayland.

I’m really happy for this… from now on I’ll try to use Wayland and I hope to don’t meet others issues for basic usage.

Thank you very much for all the devs.

I’ve unticked this as solved as, after plasma update to 6.5, I’ve this error when I go to the graphic pen settings on Wayland.

What should I do?

I’ve seen another issue.
I can’t drag the Steam window. Is it because on Wayland every program need to be set following Wayland requirements or is it a bug?

Related to this, I’ve seen that the mouse pointer don’t change its shape when I’m over the boundary of the window (if it’s not maximazed) using the graphic pen. With mouse yes.

Reopen the systemsettings thing, or reboot. It’s an annoying bug, but fortunately its transient.

Correct, Steam refuses to follow much - if any - standards including the tablet protocol. There’s nothing we can do.

I think this is fixed/might be fixed or easy to fix, please file a bug on bugs.kde.org under KWin | Input.

Done.

Ok.

Sure? I’ll try.
I know that probably it’s not super related with this but I have the same error when I run an updated live like fedora 42 or the last kubuntu release.
Anyway, I’ll try to reopen or reboot .
