If your application only requires that GLES?3.0, then you can use MESA_GLES_VERSION_OVERRIDE environment variable documented here: <a href="https://www.mesa3d.org/envvars.html" rel="noreferrer" target="_blank">https://www.mesa3d.org/envvars.html</a> . > > Adicional information: > Example laptop on Ubuntu 18: > $ apt list -a libgl1-mesa-dri > > libgl1-mesa-dri/bionic-updates,now 19.2.8-0ubuntu0~18.04.3 amd64 [instalado, autom?tico] > libgl1-mesa-dri/bionic-security 19.2.8-0ubuntu0~18.04.2 amd64 > libgl1-mesa-dri/bionic 18.0.0~rc5-1ubuntu1 amd64 > > Example laptop on Ubuntu 20: > > $ apt list -a libgl1-mesa-dri > Listando...

Hi, there is no such thing as OpenGL ES 4.6, see <a href="https://www.khronos.org/opengles/" rel="noreferrer" target="_blank">https://www.khronos.org/opengles/</a> In general, OpenGL libraries tend to support all lower versions as well, so you having support for OpenGL 4.6 (not ES) should not stop you from using OpenGL 3.0 or OpenGL ES 3.0. Please, re-check what the actual problem is.
