OpenGL 3.3 on Intel GM45 Express using the i915 driver
by royce2020 from LinuxQuestions.org on (#550E2)
I am trying to run blender on my newly installed Xubuntu 20.04. The specific error I'm getting is: "Error! Unsupported graphics card or driver.
A graphics card and driver with support for OpenGL 3.3 or higher is required."
I *think* The OpenGL version I have available is 4.3, and my Mesa version is 20, but I'm not completely sure.
I have googled this problem, and I did find a couple of solutions that didn't work for me:
- installed this PPA, and rebooted.
add-apt-repository ppa:oibaf/graphics-drivers; apt dist-upgrade
- re-installing xserver-xorg-video-intel both with and without the PPA
- setting the environment variable MESA_GL_VERSION_OVERRIDE=4.3 and when set, blender will start but almost immediately crashes with a different error: "GPUShader: compile error:
0:1(10): error: GLSL 3.30 is not supported. Supported versions are: 1.10, 1.20, and 1.00 ES"
"glxinfo|grep OpenGL" returns
