I am fixed to this Kernel, will be hard to get Weston 12 running.
Hi,
why would you say that? Did you try? Or do you mean that building
Weston and a few dependencies (not kernel, not Mesa) from source is too
much?
We are compiling our own kernel version for embedded i.MX8. Also the
Debian is our custom build and we are able to adjust to other packages
or compile parts. We know how to do that. However, we are fixed to
5.10.52 for several reasons. And I need to cross-compile Weston then,
which is maybe challenging?
I can try to compile on device and test. But which dependencies also
need to be compiled then? XWayland? Wayland? Libraries?
FWIW, when you unplug the last display, leaving none, then there is no
display area. Weston does not pretend a fake display, there just is
none. I don't know how Xwayland reacts to that, and how that Java suite
reacts to what Xwayland does. Those would be something to look into, if
Weston upgrade does not help.
Yes, it must be XWayland. Maybe there is any configuration to fix it?
Xwayland might have a fake something when all real displays are gone,
and maybe nothing then re-associates your app window from the fake
monitor to a real monitor once a real monitor appears again? No idea.
Maybe check what xrandr says while you have no displays connected? That
might give a clue, assuming the Java stack listens to RandR.
Interesting: It changes from XWAYLAND0 to XWAYLAND1 to XWAYLAND2 and
also if I have it UNPLUGGED the screen is there.
