I installed LibreELEC-Generic.x86_64-12.0.0(1).img.gz on an older Core I5 machine with Intel graphics. the OS and Kodi seemed to start fine; however, when I went to add files, I found no options to actually add them. I could see the file systems, browse them, and even play media files in them, but no option to add them.
It may be that, for some reason, Kodi is generating the button off the right side of the screen. Note I did check, and Kodi has the correct resolution for the monitor (a pretty standard 1920x1080).
Any suggestions? I am desperate to get this working as a Mother's Day gift.
