I have originally asked this question here:
But as people suggested me to ask in this forum, I am doing it.
Until yesterday, I was using chromium just fine in my Ubuntu 20.10. I don’t remember whether it started after I made an upgrade on apt-get, or after a snap refresh, but I clicked Chromium icon again and it would not start.
I tried from the terminal and I got:
libva error: vaGetDriverNameByIndex() failed with unknown libva error, driver_name = (null)
[13444:13444:0521/212248.340845:ERROR:gpu_init.cc(426)] Passthrough is not supported, GL is egl

vainfo output:

I am not 100% sure on how to debug and find the issue.
QUESTION:
What should I read to learn how to debug the above and find the error by myself?
