Looking to make an X11 compositor (like picom) in Rust with wgpu

• picom

  109 3,816 9.7 C

  A lightweight compositor for X11

I've recently become interested in X11 compositors after trying picom. I love picom's philosophy - the compositor is just a program you run and it Just Works, suddenly you have transparency or rounded corners or blur effects or whatever it is you asked it for.

• stackblur-iter

  4 8 7.6 Rust

  Discontinued A fast, iterative, correct approach to Stackblur, resulting in a very smooth and high-quality output, with no edge bleeding

With that said, I'm not particularly happy that blurring in 4K with a relatively small radius stresses out my GPU to the max, but I also have a basically constant-time software implementation that I can draw from, so we'll see how that turns out.

• InfluxDB

  Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  

• alacritty

  352 52,924 9.2 Rust

  A cross-platform, OpenGL terminal emulator.

  

If you don't have an alacritty config file, copy one into ~/.alacritty.yml.

• wgpu-external-memory

  1 1 3.2 Rust

  Experiments to allow importing and exporting external memory in wgpu.

wgpu does not integrate too well with the shared memory sadly but I do have some work to try to get something like that to work. You'll probably need to test if the pixmap is from DRI3 for the scenario I am mentioning, get the dmabuf for the texture from dri3 and then somehow get wgpu to import said texture. Although my code is really for Wayland, it should work with dri3 on X11 (it's still very WIP and not really ready yet if you want to consider this in the future): https://github.com/i509VCB/wgpu-external-memory
