Interestingly, AMD donates to Solus; yet provides poor Linux support. It is a long-standing point of contention.
oh yeah, that's normal, Adobe also donates to Linux projects I think, and yet they give... well, 0 support, I think it's just that they probably use it on the server side or something like that
AMD reused an easy template for the installer which only looks for the most common Distros.
To get around this, you can open the installation file in a text editor and change "ubuntu" to "zorin" which will allow the installer to run all the way through.
I am trying some other softwares, but the problem is of familiarity, old unfinished davinci projects and also that Davinci has many more features. Does kdenlive or any other software have any features for audio enhancements, noise reduction etc. which are available in Davinci?
