Detail

When using pd/Gem via ssh -X, [create :0< was forcing Gem to use local screen, better than the X forwarded screen.
Even if this was not officially advertised, this was very useful to debug/configure installation.
It no longer work, at least with gemglfw3window

indeed (i think; i haven't checked :-))

i did a quick check in the glfw docs, but i wasn't able to find a way to select the X-server :-/

ch-nry commented

that's alarming,
Do you know an other solution to have pd GUI on a computer and the patch/gemwindows on an other computer?

umlaeute commented

how about using [gemglxwindow] as the backend?

ch-nry commented

I switch to gemglfw3window according to this discussion : #406
I no longer know what I should use!

umlaeute commented

all right, we should figure this out :-)

  • [gemglfw3window] is a good default choice, as it is available on all major platforms and provides a consistent interface to the Gem window. the price for the consistency is that some features of more specific backends cannot be used.

  • after digging the source code of glfw, i am pretty sure that it is not possible to switch the X Display after glfw has been initialized (which is done when creating the first instance of [gemglfw3window]; more importantly, glfw can only be initialized once!).

    this basically rules out glfw as the backend if you want to open a window on a different display.
    (short of opening a feature request on https://github.com/glfw/glfw/; but I have no idea how long it would take for this to get implemented; EDIT I've opened glfw/glfw#2547)

  • so afaict the only backend that suits your needs (to open a window on a remote display), is [gemglxwindow]
    which means, that we need to unbreak it.

    #406 is a bit vague ("it is not working" resp. "it is broken") - and frankly, I forgot the off-tracker context - so it's hard to tell how to fix it. otoh, the ticket was closed by me with a commit that supposedly fixed it, so maybe it is already unbroken?

Thanks,
The rendering was black. It is now fixed. So I switch back to gemglxwindow.
I'll create new and better bug report if I notice problem in gemglxwindow.
