We specifically target integrated GPUs, and several of the main developers work on linux using Intel GPUs with open source drivers. There's every reason to think this will be amazing on Linux.

On Ubuntu 16.4 LTS, I just now installed rust nightly[1], and pathfinder[2], and the three demos appear to work in the default firefox 56, but not in chromium 61.0.3163.100[3]. Disk usage was half GB, split between ~/.cargo and pathfinder/ . Time was... less than a snack. My GPU was integrated Intel HD 520. I already had npm 3.10.3.

[1] https://www.rust-lang.org/en-US/install.html Select 2, for custom install, and change to "nightly". My host triple was x86_64-unknown-linux-gnu. [2] https://github.com/pcwalton/pathfinder [3] TextDemoView.initContext (view.ts:324) Uncaught (in promise) TypeError: Cannot read property 'createQueryEXT' of null .

EDIT: The three demos are: some text; the SVG tiger; some planar text in 3-space.

I have it enabled on one of my Firefox profiles. Would not yet recommend for normal browsing, there's still rendering errors and sometimes seemingly random performance drops, but you can definitely see it working.

That is, I have to be lucky for this benchmark [1] to not crash my "regular" Firefox Nightly. With WebRender on the other hand, the benchmark becomes entirely unimpressive, as if you were just playing a pre-rendered video.

My system has an Intel i5-3220M with HD Graphics 4000 (was midrange for a laptop in 2012) and 4GiB RAM. OS is openSUSE Tumbleweed with a KDE Plasma + bspwm combination as desktop environment, so no desktop compositor (no idea if that makes a difference).
