A simple plymouth replacement by using egl and drm.
before build, install dependencies. On Ubuntu/Debian
sudo apt-get install libglfw3-dev libglm-dev
simple version:
mkdir build
cd build
cmake ..
make
to compile successfully, you need mesa compiled with drm platform support and also gbm enabled. this is satisfied in any of modern GNU/Linux distributions. glm is required for openGLES matrix operation. for compiling demos, glfw3 is also needed.
right now, there is no installation provided. you need to run it at project dir.
./build/prometheusd -m scene -t beamwave_frag.glsl
or run text rendering mode
sudo ./build/prometheusd -m text
if you got multiple video cards, you can use -c (--card) to specify one that is in use.
sudo ./build/prometheusd -m text --card /dev/dri/card1 -T /dev/tty2
note: remember to run it at a virtual console.
these demos are immature and may harm your video card, try with caution.
- drm_tty demos how to setup kms buffer to render on.
- egl_drm_tty2 demos opengl rendered on egl surface.
- egl_drm_tty3 demos animated opengl on egl surface.
- egl_drm_shining_circle animated circling with bad frame rate (problemmatic driver maybe)
- provide scene mode plugin loader or just use binary blob like altas shaders
