From the project github page:
Kmscon is a simple terminal emulator based on linux kernel mode setting (KMS). It is an attempt to replace the in-kernel VT implementation with a userspace console.
Despite its name, KMS is not a hard requirement for KMSCON. KMSCON supports the following video backends: fbdev (Linux fbdev video backend), drm2d (Linux DRM software-rendering backend), drm3d (Linux DRM hardware-rendering backend). Make sure one of them is available on your system.
KMSCON can function as a drop-in replacement for the in-kernel linux-console. Features include:
- Full vt220 to vt510 implementation.
- Full internationalization support:
- KMSCON supports printing full Unicode glyphs, including the CJK ones.
- KMSCON provides internationalized keyboard handling through libxkbcommon, thus allowing it to use the full range of keyboard layouts supported in X keyboard.
- Hardware accelerated rendering.
- Multi-seat capability.
