I am attempting to figure out if a problem with fonts in Wine is related to my OpenGL driver (r600g). How can I temporarily switch to the llvmpipe software renderer to perform testing, then switch back to r600g? I am using Kubuntu 16.04 with Radeon HD 3200 graphics. Thanks.

You can use the LIBGL_ALWAYS_SOFTWARE environment variable to force software rendering on a per-application basis:
LIBGL_ALWAYS_SOFTWARE=1 [application] [arguments ...] It only works if you are using mesa (which you probably are).

- Thanks! I read about this environment variable but was under the impression that it used swrast, which is supposed to be "old and broken". But it does indeed use llvmpipe.triskit– triskit2016-12-17 14:22:48 +00:00Commented Dec 17, 2016 at 14:22
- In case you are not using mesa (but e.g. nvidia), you may resort to using Xephyr.Hermann– Hermann2021-03-14 01:44:35 +00:00Commented Mar 14, 2021 at 1:44
