# DeviceSpec: API `drm()` from server `linux()`:

The API is Linux DRM/KMS. The server is Linux itself. This server provides
direct capture of frames at the kernel so it works for both Linux and Wayland.
There's a program known as GPU Screen Recorder that is able to use this to
capture specific windows on X11, but the window-specific capture doesn't work
with Wayland. Irrespective, whole-screen capture works on both GFX servers.

Notes:
* `modetest` utility in ubuntu package `libdrm-tests` is relevant.
* `kmscube` is apparently relevant.
* `drm_info` from ubuntu pkg `drm-info`is relevant.
