Bug 624958 – GNOME nvidia wayland support

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Mart Raudsepp 2017-07-14 09:03:05 UTC]

We currently don't support GNOME nvidia wayland on top of EGLStreams, but it would be nice to figure it out and support it to some capacity. Sadly (actually fortunately) I don't have nvidia hardware, thus input from others highly sought here.

What I do know:

* mutter has a default disabled --enable-egl-device knob, which is required for nvidia EGLDevice/EGLStreams support to be turned on. The mutter ebuild currently does not pass that. Note that configure.ac is broken - if --disable-egl-device is passed, it'll get enabled instead, so be careful about use_enable there (not sure there's any point fixing it over just conditionally passing only --enable, as things are moving over to meson instead soon)

* I don't think we have a good glvnd story for the hybrid graphics aspects of overall nvidia, which isn't that much wayland related, and improvements here could be useful for pure Xorg as well (but related via Xwayland and GL support under Wayland)

* I believe OpenGL in Xwayland doesn't work with nvidia-wayland yet, Red Hat and NV are still working on that

I tried to enable EGLDevice but clutter backends fail to initialize. Even when building with USE=debug it does not produce a useful info (as a side note eselect opengl does not replace libEGL).

For the eselect opengl part you might want to ask input from X11 team.

Deferring to 3.26, maybe by the time we get further along with 3.26 there are better news about GL in NV Xwayland too.

Targeting for 3.30 (3.30 itself is more important than wayland for nvidia); but help on this matter welcome from others earlier, of course

Both GDM and GNOME wayland session works with proper setup (disabling nvidia udev rule and enabling EGLDevice) and Gentoo-stable GNOME 3.30.
However I didn't tested overall experience, but got some glvnd error from Steam client and some minor header glitches from Thunderbird under kdocker.

Passing "--disable-egl-device" is not enough. configure.ac should be patched

This can't proceed until someone packages https://github.com/NVIDIA/egl-wayland or whatever else provides wayland-eglstream-protocols.pc

I think this all works now.
