How old are your laptops? For ease of development, webrender2 is configured to compile with the latest OpenGl 4.x features. I believe there is a way to build it to target a lower OpenGl version. Edit: Correction, its currently targeted at OpenGl 3.2. There's an open issue for bringing it down to OpenGl 3.1 which is the version supported by integrated Sandybridge GPUs. Considering 40% of people running Intel are using Sandybridge or older, that's probably why it wont run on your laptops.

Youngest laptop here is from 2011: Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller OpenGL renderer string: Mesa DRI Intel(R) 965GM Maximum OpenGL version for that chipset is 2.0, apparently, though I can't find a way to push it beyond 1.4 on Linux I appreciate that six years old is ancient by SV standards but I would be interested to learn what proportion of Firefox users are on equally old hardware. I did try launching Servo with CPU rendering but it hung indefinitely.

  Servo isn't a production ready consumer browser and it won't be for a long time because its purpose is to facilitate research into parallel browser engines. While a 2007 chipset may not be very old among the average consumer, it is probably not going to work for a developer machine that's going to be compiling a huge codebase under active development. I don't think the software fallback has gotten much love but AFAIK it'll work fine once llvmpipe support is added to webrender2 [1]. Once that is done, rendering will work with the vast majority of laptops and desktops running Linux/MacOS/Windows. The OpenGL version supported by that chipset is over a decade old so devoting time to compatibility this early in the project would be a waste of time (and defeat the purpose since the standard predates the explosion of mobile devices).
