Description Joonas Niilola gentoo-dev 2020-11-28 10:12:23 UTC
This bug is more of a reminder for myself, and an opening to discuss for anyone with concerns about it.

This REQUIRED_USE is tedious, and impossible to solve profile-wise. 
  RequiredUseDefaults: version 1.25.1-r2: profile: 'default/linux/amd64/17.1/desktop/gnome' (23 total) failed REQUIRED_USE: !opengl
  RequiredUseDefaults: version 1.25.1-r2: profile: 'default/linux/amd64/17.1/desktop/gnome' (23 total) failed REQUIRED_USE: gles2-only

Starting from next version bump, I'll be switching the logic to choose opengl implementation from REQUIRED_USE to simply detect state of normal USE flags.

if use X && ! use wayland; then

if use wayland; then

else (or if ! use X && ! use wayland)

GL acceleration can still be enabled/disabled from e's settings regardless of opengl configure option, this shouldn't break existing systems.

Then something needs to be decided how to deal with 'drm', as it only works with gles2+wayland and not with opengl+X.

    dev-libs/efl: rework opengl-gles2 logic
     - 'opengl' is barely supported by upstream, and es-egl will provide
        similar experience. Even if they're compiled in, hwaccel can be
        disabled from the settings.
