there are no other drivers on linux. nvidia ships windows blob with shim

There are. For example - AMDGPU-Pro (doesn't using Mesa). Nobody said that only Mesa drivers are "true drivers for Linux". Nvidia driver is Linux driver, just like Mesa. So no, GBM isn't multiplatform. GBM is Mesa only.

GBM isn't not supported by all drivers. It's supported by Mesa drivers. It's not 'all'.

so, not wayland, but two compositors support this nvidia-only hack
of course i can. gbm is supported by all compositors and all drivers.

GBM isn't not supported by all drivers. It's supported by Mesa drivers. It's not 'all'. EGL Streams is still Wayland compatible and lack of GBM support doesn't matter in this. Wayland doesn't specify API to buffer management, so GBM isn't more important solution than EGL Streams. It's Mesa solution, not Linux or Wayland solution.

GNOME, Enlightenment and umerged patches to Weston.

You can't tell GBM compositor/driver is Wayland compatible, while EGL Streams not.

and how many of those support "supported ny nvidia" egl steams?

GNOME, Enlightenment and umerged patches to Weston.

Does it matter? Wayland isn't GBM only and leave buffer management API to compositor. You can't tell GBM compositor/driver is Wayland compatible, while EGL Streams not. Wayland doesn't depends on them.

Back to topic, please...

Why can't they standardize the Virtual Machine/Hypervisor drivers and all Virtual Machines/Hypervisors use the same? This is a mess, code duplication nonsense to me...

[pal666]

Nvidia support Wayland (Wayland doesn't specify which API for buffer management driver must contain, so without GBM Nvidia still support Wayland with EGL Streams). As for desktop You have GNOME, Enlightenment, almost ready KDE (5.12 will be Wayland focused release) and a few small compositors (sway etc.).

and how many of those support "supported ny nvidia" egl steams?

[pal666]

As for Wayland, I never really saw the point in it. It is true, X needs a new extension for interapplication security that would restrict apps to their own Window, but some apps like screensavers and screengrabbers can be given special permissions, but otherwise the X System is fine.

it is a pity that you do not develop X while most of X devs are switched to developing wayland

[pal666]

*only on GNOME.

you mean only in default desktop?

[pal666]

You have not noted in 4 years that in Linux world applications comes first then programming interfaces.

you have not noted in 2 years than number of wayland desktops and applications is steadily increasing, not the other way around
