Headless GPU usage is a pretty normal use-case today. Well, that's why
we have separate device nodes for running displays and for
rendering/compute.

And quoting from the DRM-UAPI documentation:
> With the increased use of offscreen renderers and GPGPU applications, clients no longer require running compositors or graphics servers to make use of a GPU. But the DRM API required unprivileged clients to authenticate to a DRM-Master prior to getting GPU access. To avoid this step and to grant clients GPU access without authenticating, render nodes were introduced.

I also agree with this comment from pnowack upstream:
> CPU resources are in any case more precious than GPU resources (bottleneck-wise).

If an unauthorized process trying to use the GPU ends up using swrast,
that has a worse impact on the system.

Title:
  gnome-remote-desktop uses software rendering

Status in GNOME Remote Desktop:
  New
Status in gnome-remote-desktop package in Ubuntu:
  Triaged
Status in gnome-shell package in Ubuntu:

Status in systemd package in Ubuntu:

Bug description:
  gnome-remote-desktop uses software rendering by default, which is
  incredible slow on some hardwares. If the user is added to the video
  and render group, graphics acceleration is used. These groups are not
  in the default, so I think it would make sense to add them.
