Following the story with the ElementaryOS, and coexisting with my Windows 10 installation, all the sudden, Linux started working once again after few reboots. Not sure what happened, didn’t do anything but… it worked. There was an error with no internet, but it looks like it needed to do something with the /etc/resolv.conf file.
To be honest, I don’t remember what I did, but it works now.
There was another issue with Opera browser not being able to play youtube videos, looks like there’s an issue with H.264 codecs; I had to download the chromium codecs and link a library file. Now it works just fine. Here’s the solution.
Until next problem arises of course! 😉
