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. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/2077538 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: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: gnome-remote-desktop uses software rendering by default, which is incredible slow on some hardwares.
