# Wayland backend for GNUstep
|
||
|
|
|
||
|
|
This directory (along with `Headers/wayland/`, and a file in `Source/cairo/`
|
||
|
|
and `Headers/cairo`) contains the Wayland backend for GNUstep GUI. This
|
||
|
|
display server backend depends on Cairo graphics backend; it will currently
|
||
|
|
not work with any other combination.
|
||
|
|
|
||
|
|
As of April 2020, it is incomplete and broken. Help getting it functional will
|
||
|
|
be appreciated.
|
||
|
|
|
||
|
|
## Known issues
|
||
|
|
|
||
|
|
Last updated 25 April 2020:
|
||
|
|
|
||
|
|
* Under Weston, some backing Cairo surfaces, which should not be visible in
|
||
|
|
the compositor, are nonetheless drawn randomly onto the screen.
|
||
|
|
* Backing view surfaces may never get blitted onto the main window.
|
||
|
|
* After a while, Weston assumes that the application is not responding (there
|
||
|
|
is a spinner when hovering over the windows, and the surfaces can be
|
||
|
|
rotated by holding the right mouse button). Some events still get
|
||
|
|
delivered, visible in the debug output, but otherwise the application
|
||
|
|
appears frozen.
|
||
|
|
|
||
|
|
## Use on Debian
|
||
|
|
|
||
|
|
As of April 2020, it requires the stable XDG Shell protocol to be available in
|
||
|
|
the compositor you may be using. Weston included in Debian buster does _not_
|
||
|
|
include the stable XDG Shell protocol; this was only checked into Weston in
|
||
|
|
February 2019, and seemingly released with Weston 6, which does not ship in
|
||
|
|
Debian buster.

## Regenerating protocol files
|
||
|
|
|
||
|
|
To regenerate protocol sources from protocol IDLs in XML format, please use
|
||
|
|
`wayland-regenerate.sh`. Paths to the XML files are hardcoded to the values on
|
||
|
|
a Debian testing system.
