I have 3 computers I primarily run Blender on, 2 of which are giving me this error:
**Error! Unsupported graphics card or driver.
A graphics card and driver with support for OpenGL 3.3 or higher is required.
The program will now close.**
but if I run Blender 3.3 on those machines, it works perfectly.
Computer 1 is Ubuntu 20.04 with an AMD GPU, it runs 3.4 Computer 2 is Ubuntu 20.04 with intel graphics only, it shows the symptoms above Computer 3 is old hardware running Mint 20 with NVidia graphics, it shows the above.
3.3 works fine on all three computers.
an example of glxinfo | grep -i opengl
(from computer 2)
OpenGL vendor string: Intel

I think this means its running OpenGL 4.6? From my research though, the minimum requirement for OpenGL 3.3 is not new to Blender 3.4, this actually became a requirement a long time ago. but I am suddenly seeing this problem.
