I recently installed OBS Studio under Ubuntu 20.04 LTS on my laptop (a Lenovo Thinkpad T410). While I didn't encounter any issue during the installation, I am unable to run OBS Studio itself, as I keep running into the following error:
Failed to initialize video. Your GPU may not be supported, or your graphics drivers may need to be updated.
In order to provide you with all the necessary details, here is the complete console output of the obs command:

After searching the issue, it appears my problem is that I have a too old OpenGL version (2.1). While my GPU (integrated; my CPU being Intel i5 M520) isn't cutting-edge, it doesn't seem to be too old for OBS Studio because I also installed the same program on my Windows 10 (as my laptop is a dual boot) and I had no issue running it to capture from my webcam or from an opened window.
However, I have a hard time finding out how I can upgrade my OpenGL version under Ubuntu 20.04. My best attempt was to get a more up-to-date version of the Mesa 3D library via the kisak-mesa PPA, but while it upgraded my version of Mesa, it didn't change the OpenGL version. Here is what I get when I run the glxinfo | grep "OpenGL version" command:
OpenGL version string: 2.1 Mesa 20.2.1 - kisak-mesa PPA
On a side note, I also had a look at the Additional drivers tab in Softwares & Updates, but this tab is completely empty in my case and doesn't suggest any driver that could improve my current situation.
What could I do to this fix ? Another recent question suggests installing OBS Studio via snap, but despite trying that, I get the same issue as before.
Many thanks in advance for your help.
