X11 mouse is invisible even if hideCursor is false

x11Init assumes you're going to be hiding the mouse, so defines the cursor unconditionally.

FWIW the 'dot' cursor is always invisible on my system if it works at all.

I don't see a good way to fix this. The other option is to take the XDefineCursor call out of x11Init() entirely, and leave it up to the rest of the code if .SetPointer() should be used.

FWIW I don't think this should be merged. It's crude, it exports more information across module boundaries and it's not obvious from looking at the source that LGDS_X11.setPointer() might not point to x11SetPointer(). It's mostly here to demonstrate the issue I'm having and a way to demo the desired behavior.

Fundamentally the issue here is that if we call setPointer() at any point we've taken charge of the pointer from the window manager. I think setting input:hideMouse=no (or a similar flag) should just leave it alone. There's only 7 callsites and a number of them are in the same function.
