Hi, Have to report the same problem with someone from the french community using a Intel NUC (Intel GPU), and using Ubuntu 20.04 as OS. The issue happen more often when using the gizmo to rescale an object. The UI freeze and he can only force quit Blender.

I can understand you. I don't have much income too. If you can do it, you could try to install XUbuntu on this old PC just to be sure it's not related to the distro, since your other PC run fine on this distro. If you install XUbuntu and there is no issue, the you will know it's something in your distro, if it's still persist in the problem then we will have a confirmation that it's hardware related.

Unfortunately, If I'm not wrong, this are compiler directives to build using theses CPU extensions.
The only way I would know is to modify the code to not use the extensions your CPU is not supporting (still a guess, I'm not sure the developper uses theses extension, but it would made sense as it accelerate lots of things)
Thanks for the info about your hardware. I'm not totally sure, but Blender might use some CPU extensions that are not supported by the old Pentium 4 (Like SSE), but are present on the newer Intel Atom.

You did not mention what CPU you have, how much ram. CPU Spike could be happening with libraries that are needed by Blender, but your distro have problem with them. Do you have another PC with another Linux version to check?
This seem directly related to the OpenGL support of your card in your environment. Using "Software-gl" is only using the CPU to do everything. Have you tried something else that require HARDWARE OPENGL on your system? It almost look like you don't have openGL drivers installed. Version 2.79 is less demanding for video card requirement and can almost run on anything.
They added draw call batching in 2.81 to make it faster. (23 sept) The problem is probably related to this. Your old video card seem to have difficulty with this.
