We don't have any good means to ensure GLES availability from drivers via libglvnd or virtuals. Given that nvidia-drivers just unconditionally provides gles2, it's need is widespread (even strongly preferred over "full" GL in case of e.g. webkit-gtk, mutter, gstreamer-1.24, gtk-4.14+ and more), please consider just unconditionally enabling it. If not, we need to figure out some way to ensure working GLES2/GLES3 drivers.
Not super familiar with mesa but seconding this idea, adds no dependencies and don't think many would want to skip this (if really must, could package.use.force rather than drop USE then if someone really need this they could unforce it into an unsupported configuration). Does need to force opengl as well, but sounds fine. I also like the idea of preventing the alternate path here: if use opengl || use gles1 || use gles2; then emesonargs+=( -Degl=enabled -Dgbm=enabled -Dglvnd=true ) else emesonargs+=( -Degl=disabled -Dgbm=disabled -Dglvnd=false ) fi Given currently packages expect mesa to always provide libgbm.so (since USE=gbm is gone), but gbm=disabled can remove it.
(In reply to Ionen Wolkens from comment #1) > Does need to force opengl as well, but sounds fine. Nevermind this bit, was looking at REQUIRED_USE but I missed it's behind "X?". Could stay optional I guess. REQUIRED_USE="X? ( gles1? ( opengl ) gles2? ( opengl ) )"

Agreed. I checked and since we always use libglvnd, media-libs/mesa's IUSE="gles1" and IUSE="gles2" flags add only a trivial increase in file size: From USE="-gles1 -gles2" to USE="-gles1 gles2": > ./usr/lib/dri/swrast_dri.so (mode: -rwxr-xr-x, refs: 5, size: 22949840 → 23003056, +53216 bytes, +0.23%) > ./usr/lib64/dri/swrast_dri.so (mode: -rwxr-xr-x, refs: 5, size: 22692872 → 22746152, +53280 bytes, +0.23%) And from USE="-gles1 gles2" to USE="gles1 gles2": > ./usr/lib/dri/swrast_dri.so (mode: -rwxr-xr-x, refs: 5, size: 23003056 → 23027632, +24576 bytes, +0.11%) > ./usr/lib64/dri/swrast_dri.so (mode: -rwxr-xr-x, refs: 5, size: 22746152 → 22758440, +12288 bytes, +0.05%) Since ultimately we'll want to be able to disable OpenGL support entirely, I think tying these to IUSE=opengl (which is forced on currently and for the foreseeable future) is the right thing to do.

I think with this change some ebuilds will need to tweak their dependency on media-libs/mesa a bit, here are just some of them: >=media-libs/mesa-9.1.6[abi_x86_64(-),gles2] required by (media-libs/libsdl2-2.28.5:0/0::gentoo, installed) USE="X custom-cflags dbus gles2 haptic joystick opengl pipewire sound threads udev video vulkan wayland -alsa (-aqua) -doc -fcitx4 -gles1 -ibus -jack -kms -libsamplerate -nas -oss -pulseaudio -sndio -static-libs -test -xscreensaver" ABI_X86="(64) -32 (-x32)" CPU_FLAGS_X86="mmx sse sse2 -3dnow" VIDEO_CARDS="(-vc4)" ^^^^^ >=media-libs/mesa-9.1.6[abi_x86_64(-),egl(+),gles2,wayland] required by (media-libs/libsdl2-2.28.5:0/0::gentoo, installed) USE="X custom-cflags dbus gles2 haptic joystick opengl pipewire sound threads udev video vulkan wayland -alsa (-aqua) -doc -fcitx4 -gles1 -ibus -jack -kms -libsamplerate -nas -oss -pulseaudio -sndio -static-libs -test -xscreensaver" ABI_X86="(64) -32 (-x32)" CPU_FLAGS_X86="mmx sse sse2 -3dnow" VIDEO_CARDS="(-vc4)" ^^^^^ >=media-libs/mesa-9.0[egl(+),gles2,wayland,abi_x86_64(-)] required by (media-libs/gst-plugins-base-1.22.11:1.0/1.0::gentoo, installed) USE="X egl gles2 introspection nls ogg opengl orc pango wayland -alsa -gbm -ivorbis -test -theora -vorbis" ABI_X86="(64) -32 (-x32)" ^^^^^ media-libs/mesa[abi_x86_64(-),egl(+),wayland,X] required by (x11-apps/mesa-progs-8.5.0:0/0::gentoo, installed) USE="X wayland -gles2" ABI_X86="(64) -32 (-x32)"
Generally speaking, ebuilds shouldn't even depend on mesa unless they link with libgbm. mesa is just one vendor, and they should at most only want libglvnd and leave the rest up to VIDEO_CARDS and such.

media-libs/gst-plugins-base media-plugins/gst-plugins-vaapi Need fixing
Adding a (+) to the gles2 flag on the mesa dependency fixes it I think A quick grep suggests: dev-debug/apitrace dev-games/ogre dev-libs/efl games-arcade/jazz2 games-engines/scummvm gui-libs/wlroots gui-wm/wayfire gui-wm/sway gui-wm/hyprland kde-plasma/kinfocenter kde-plasma/kwin mate-base/mate-session-manager media-libs/cogl media-libs/libprojectm media-libs/freeglut media-libs/gst-plugins-base media-plugins/gst-plugins-vaapi media-tv/kodi sys-apps/kmscon www-plugins/lightspark x11-apps/mesa-progs x11-wm/muffin Need fixing, it might be easier to revert the change until that can be done
grep "media-libs/mesa" */*/*.ebuild | grep gles2 | grep -v "gles2(+)" | cut -d/ -f -2 | sort -u
And these 3 for gles1 which is also in the above list dev-debug/apitrace games-engines/scummvm media-libs/freeglut
