Whether to set up NixOS such that TurboVNC's built-in software OpenGL
|
|
implementation works.

This will enable <option>hardware.opengl.enable</option> so that OpenGL
|
|
programs can find Mesa's llvmpipe drivers.
|
|
|
|
Setting this option to <code>false</code> does not mean that software
|
|
OpenGL won't work; it may still work depending on your system
|
|
configuration.
|
|
|
|
This option is also intended to generate warnings if you are using some
|
|
configuration that's incompatible with using headless software OpenGL
|
|
in TurboVNC.

|
# the indiviudual applications (e.g. `glxgears`) also need to directly load
|
|
# the OpenGL libs.
|
|
# Thus, this creates `/run/opengl-driver` populated by Mesa so that the applications
|
|
# can find the llvmpipe `swrast.so` software rendering DRI lib via `libglvnd`.
