SikuliLibrary not working on wayland

[damies13]

Hi,

I am trying to use SikuliLibrary on Ubuntu 22.04 I managed to install all the prerequisites (the documentation needs updating) and got to the point where the click keyword attempts to run, then I get timeout could not find image, a screen shot is taken and it's completely black.

Ubuntu 22.04 defaults to wayland and I suspect that is the issue, I'm aware this could be an upstream issue with SikuliX but not sure how to confirm this, if you can confirm can you raise an issue with the SikuliX project and link to this. Also mentioning in the documentation that SikuliLibrary is not compatible with wayland would be a good idea

FYI The documentation needs updating:

• Java is a prerequisite (there is no java installed by default, pip install doesn't install java or mention it's required)
• After installing Java the test log mentioned opencv was missing and gave instruction to install for ubuntu 20.04 (opencv4.2) on Ubuntu 22.04 I needed to adjust those instructions to opencv4.5
• These prerequisites should be mentioned in the Pip installation section

As a workaround on Ubuntu 22.04, logout, at the login screen switch to Xorg (X11) and log back in and SikuliLibrary does work for me.
