Blender Asked by user101746 on November 25, 2021
The problem:
Blender does not start and prints the following error message:
Error! Unsupported graphics card or driver.
A graphics card and driver with
support for OpenGL 3.3 or higher is required.
Background:
Blender should run on a virtual linux system started from a terminal with a X Server. The system gets the graphic card (NVIDIA Tesla P100 Card) by passthrough with OpenGL 4.6.
How to force blender to use this graphic card?
Is there a config file, where the graphic card could be explicit set before the start of blender?
Or is there some configuration of the X Server or the virtual system neccessary?
Usage:
I want to use blender for rendering images of 3D models.
Blender was displaying the same error message to me. My problem was that in addition to the video ports provided by my AMD RX 580 graphics card which supports OpenGL 4.6, the motherboard also provided an HDMI video port that did not support OpenGL 3.3. However, my monitor was plugged into the less capable port. Switching the monitor cable to the port on the graphics card solved the issue.

Could it be, that the issue is caused, because blender required some sound card?
No, it is probably cause by an indirect rendering setting for the graphic card driver similar as mentioned here. The warning ALSA lib confmisc.c:767:(parse_card) cannot find card '0' is probably caused by a missing sound device, but can suppressed by ./blender -noaudio.
