Type of device* : Tablet and Desktop PC
Brand and version of the device: Lenovo Tab P11 Plus tablet, Precision Pen 2 Stylus MSI Cubi 5 PC
System** : Linux Mint 21.2
Using Weylux to connect my tablet to my PC I can’t get the stylus to do anything but move the ‘paper’ on the screens no matter what option I select. What am I doing wrong please?
Hello @MikeH, and welcome to the forum!
Sorry, but you will probably do not like my answer. 
Well, what are you doing wrong?
I would start by saying that you are trying, at least judging by the sparse documentation, to get a rather experimental hardware combination to work with the help of experimental software.
The “documentation” briefly discusses all sorts of things, but nothing is really described in detail. This is software for cracks who have a solid knowledge of many aspects of computer technology and who can solve any problems themselves, which is even pointed out in one place (or were it more?) in the documentation.
This bridging software connects devices that were not made to be paired together to give them functionality that they were not designed for, that they were not meant to have. Yes, you can draw, paint and animate on tablets with Krita and other programs, for example, but these programs were then programmed for exactly this hardware, not for a combination of hardware not meant to do what you want it to do. And yes, there are of course people where it works, but I see them as the chosen ones, or the lucky ones. And I’ll bet, the devs only made it work for their hardware, and the publication was meant for those who are able to find the way to make it work themselves, at least when I see the issue tracker.
You can try to contact the developers of this project, but you will probably have already tried without success. Or have you given up on the 108 unanswered questions in the issue tracker, because the oldest one is 4 years old?
Here you are trying to convert a tablet computer into a pen display connected to another computer. That sounds great, but technically this is highly ambitious! What’s more, the 7 developers who contributed to it stopped further development of this project three years ago, which should give you pause for thought. I can’t say whether this Weylus software has problems with your Intel UHD 620 graphics, but the description only mentions Nvidia. In my opinion, you can save yourself a lot of trouble if you either look around for other software with this function that is available for Linux and preferably still offers support in the form of active developers, or buy a graphics tablet for your computer, it doesn’t necessarily have to be a pen display, even if the manufacturers of these tablets want to persuade us otherwise.
Yes, I know, from my brief research this seems to be the only software of its kind available for Linux.
I also know that there are working solutions in the commercial sector to control an iPad or Android tablet with macOS or Windows and use it as a graphics tablet. These solutions are probably now also reasonably stable, but this has taken a lot of developer time and therefore money and was certainly not a leisure project by a small group of programmers, but a full-time project by development departments. And even users of these niche solutions occasionally ask for support here because this or that is stuck, as it was never intended to work like this. Something that is not easy for us to manage, as we usually have no experience with such experimental combinations ourselves and can only make assumptions. And often we can’t help either.
So, at least I have to say, sorry I have no idea where you could be stuck, after I’ve read through the “documentation”. Maybe you are using Wayland, a solution that is known to have issues with Krita and additionally named as “problematic” by the devs of Weylus. But this is only a bold guess.

Thanks @Michelist .
The TL;DR seems to be that I’m doing everything wrong. Oh well, it looks like I’m going to have to invest in a suitable graphics tablet.
Your computer skills are unknown to me, as is your willingness to learn and ability to sink your teeth into something in order to complete your chosen task.
But the way I see it, you have to be lucky to have hardware that is relatively well suited to the software, both computer and tablet should not be anything exotic, you should have Nvidia graphics if possible, then at least solid knowledge of the command line is helpful and everything else I have already put out of my mind. And then it mainly comes down to willpower and perseverance (and possibly also programming skills).
But you should bear in mind that developments and changes are still rapid, at least in the field of computer graphics. I don’t know how up-to-date your PC is and “how far away it is from this software”, i.e. technologically. Furthermore, the software hasn’t been maintained for years and the developers stopped responding to messages in the issue tracker even before the software was put on ice, so you can’t expect any help from them.
So I don’t think your idea of moving towards a real graphics tablet is the worst idea.
And it doesn’t have to be a pen display, I don’t have one myself and got along fine without one when I was still able to use it properly. But both tablets with and without a display have their advantages and disadvantages, you have to decide for yourself which is the best solution for you.
Instead of an Android tablet connected to a PC, you might end up with a pen computer. Then you would have the performance of a decent PC with similar features of an Android tablet and a decent pen display as well and, if necessary, you could sell the mini PC and Android tablet to finance it, because these portable pen displays with a built-in PC are not cheap if they are to be powerful.

If you’re running Linux Mint then I’d recommend getting a small (not too small) Wacom graphics tablet. Linux Mint has a FOSS Wacom driver already incorporated into it.
Thanks. I know my way around the command line fairly well but my programming skills are virtually non existent these days.
I don’t see me going for a pen computer at this stage and even if I did I wouldn’t sell either my tablet or desktop machines to pay for it. I am considering an inexpensive Wacom tablet though but I think that’s a topic for another thread, possibly even another category.
Thanks for your help, again and I think I’ll close this topic now.
