OBS Studio not working ("Failed to initalize video" error) (Dell Inspiron 6400) (Lubuntu 20.04.1 LTS)

I installed OBS Studio via Discover, but, when I open it, it gives the following error dialogue, and then quits:

Failed to initialize video. Your GPU may not be supported, or your graphics drivers may need to be updated.

Is there any solution to this problem? I am using a Dell Inspiron 6400 laptop with Lubuntu 20.04.1 LTS (dual boot with an old version of Windows). In case it were relevant in diagnosing the problem, here are some of my CPU details (extracted via lshw):

I have read a few fora online, most of them concerning Windows operating systems. Some suggest the situation can be resolved by installing a third-party plug-in; others say that it is an inherent limitation of the hardware, and that no solution is possible (short of changing the graphics card inside the machine or getting a new computer).

If it would not be possible (or would be very difficult) to make OBS Studio work, I would be interested to hear about any alternatives that would work (NB: I already have Audacity, but that does not do video). I know my laptop is old, but it does manage to run Audacity, Zoom, and Skype without problems (as long as I do not try to run them simultaneously!), so I am hopeful that there would be some means of editing video and even broadcasting it in real time. I know VLC can receive live broadcasts, but am not clear as to whether it has a webcam+mic live broadcasting mechanism.

According to this forum post, the graphic card must support at least OpenGL 3.2.

You can check it with

sudo apt install mesa-utils
glxinfo | grep OpenGL

I have just taken the steps described by apt-ghetto. The relevant line from the output of glxinfo | grep OpenGL suggests that my graphics card does not support OpenGL 3.2:

OpenGL version string: 1.4 Mesa 20.0.8

The forum post cited by apt-ghetto makes some mention of the possibility of upgrading drivers (“sometimes you can try updating drivers”), so I might look into trying that (when I have more time on my hands), if I can find any upgrades. However, it is looking like my hardware will not support OBS Studio.

You have a log of OBS?

Sorry, I do not understand what you mean by “a log of OBS”. Do you mean the output if I attempt to run via Terminal? If so, this is what I got upon running obs:

It looks like I have a solution. From the forum hyperlink posted by Noumeno, I discovered that the following Terminal command launched the application successfully for me:

LIBGL_ALWAYS_SOFTWARE=1 obs

(NB: one has to use this command each time, although the forum suggests a way of setting it as default, which I have not yet tried).

I have successfully loaded OBS Studio, although I have not yet got round to actually recording/streaming something yet. In the meantime, many thanks.

Ignore this message – it is simply to keep the thread open for another month (I have not yet got round to actually recording/streaming something, and intend to post an update if/when I have done so successfully).
