Failed to create OpenGL context
glxinfo also shows Error of failed request
For me the following fixed the issue:
I use the Nouveau video driver with my nVidia card, so I removed all nVidia drivers first:
sudo apt purge nvidia*
Next, reinstall the xorg drivers and mesa:
sudo apt install --reinstall xserver-xorg-video-nouveau libgl1-mesa-glx
Reboot
