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. See kmscon(1) man-page for usage information.
|
|
|

Website:
|
|
http://www.freedesktop.org/wiki/Software/kmscon
|
|
|
|
== Requirements ==
|
|
|
|
Kmscon requires the following software:
|
|
- libtsm: terminal emulator state machine
|
|
http://www.freedesktop.org/wiki/Software/kmscon/libtsm/
|
|
- libudev: providing input, video, etc. device hotplug support (>=v172)
|
|
http://www.freedesktop.org/wiki/Software/systemd/
|
|
- libxkbcommon: providing internationalized keyboard handling
|
|
http://xkbcommon.org/
|
|
- libdrm: graphics access to DRM/KMS subsystem
|
|
- linux-headers: linux kernel headers for ABI definitions
|
|
|
|
Everything else is optional:
|
|
|
|
For video output at least one of the following is required:
|
|
- fbdev: For framebuffer video output the kernel headers must be installed
|
|
and located in the default include path.
|
|
- DRM: For unaccelerated drm output the "libdrm" library must be installed
|
|
and accessible via pkg-config.
|
|
- OpenGLES2: For accelerated video output via OpenGLESv2 the following must
|
|
be installed: libdrm, libgbm, egl, glesv2 (i.e., mesa)
|
|
|
|
For font handling the following is required:
|
|
- 8x16: The 8x16 font is a static built-in font which does not require
|
|
external dependencies.
|
|
- unifont: Static font without external dependencies.
|
|
- pango: drawing text with pango
|
|
Pango requires: glib, pango, fontconfig, freetype2 and more
|
|
|
|
For multi-seat support you need the following packages:
|
|
- systemd: Actually only the systemd-logind daemon and library is required.
|
|
|
|
== Download ==
|
|
|
|
Released tarballs can be found at:
|
|
http://www.freedesktop.org/software/kmscon/releases
|
|
|
|
== Install ==
|
|
|
|
To compile the kmscon binary, run the standard autotools commands:
|
|
$ test -f ./configure || NOCONFIGURE=1 ./autogen.sh
|
|
$ ./configure
|
|
$ make
|
|
$ make install
|
|
To compile the test applications, run:
|
|
$ make check
|
|
|
|
If you want only a very basic kmscon program without any major dependencies,
|
|
use:
|
|
$ ./configure --with-video=fbdev,drm2d --with-renderers= --with-fonts=unifont --disable-multi-seat --with-sessions=dummy,terminal
|
|
However, you will loose a lot of functionality by dropping all dependencies.
|
|
|
|
The following configure options are available. If build-time dependencies
|
|
cannot be satisfied, an option is automatically turned off, except if you
|
|
explicitly enable it via command line:
|
|
--enable-multi-seat: This requires the systemd-logind library to provide
|
|
multi-seat support for kmscon. [default: on]
|
|
--enable-debug: Enable debug mode/messages [default: on]
|
|
--enable-optimizations: Enable code optimizations [default: on]
|
|
|
|
Backends for several subsystems in kmscon can be selected with the following
|
|
options (all of them take a comma-separated list of backend names):
|
|
--with-video: Video backens. Available backends are:
|
|
- fbdev: Linux fbdev video backend
|
|
- drm2d: Linux DRM software-rendering backend
|
|
- drm3d: Linux DRM hardware-rendering backend
|
|
Default is: fbdev,drm2d,drm3d
|
|
--with-fonts: Font renderers. Available backends are:
|
|
- unifont: Static built-in non-scalable font (Unicode Unifont)
|
|
- pango: Pango based scalable font renderer
|
|
Default is: unifont,pango
|
|
The 8x16 backend is always built-in.
|
|
--with-renderers: Console rendering backends. Available are:
|
|
- bbulk: Simple 2D software-renderer (bulk-mode)
|
|
- gltex: OpenGLESv2 accelerated renderer
|
|
- pixman: pixman based renderer
|
|
Default is: bbulk,gltex
|
|
The bblit backend is always built-in.
|
|
--with-sessions: Built in sessions. Available sessions are:
|
|
- dummy: Dummy fallback session
|
|
- terminal: Terminal-emulator sessions
|
|
|
|
== Running ==
|
|
|
|
To get usage information, run:
|
|
$ ./kmscon --help
|
|
You can then run kmscon with:
|
|
$ ./kmscon [options]
|
|
|
|
For debug output use "--debug". For verbose output use "--verbose".
|
|
With "--xkb-layout=<lang>" you can switch the keyboard layout.
|
|
See "man kmscon" / kmscon(1) for more information.
