OpenSCAD grumps about not finding OpenGL 2.0 whenever it starts up on my ancient laptop, which is tedious: that situation just isn’t going to change. Not a fatal error, although I do wonder what the OpenCSG rendering would look like.
Anyhow, a bit of rummaging turns up a hack that’ll cause OpenSCAD to STFU and just start up. That doesn’t make OpenCSG work, which is pretty much not a problem for my simple needs.
On Ubuntu-flavored distros, install driconf, then activate two options (in the Performance and Debugging tabs, respectively):
- Enable limited ARB_fragment_shader support on 915/945
- Enable stub ARB_occlusion_query support on 915/945
And then It Just Works…
