I had this issue before with ubuntu 16.04lts. The weird part is that it worked fine until one update that failed, i believe it was by end of 2017. unfortunately and go figure ;),had same issue with the previous version of elementaryOS, mint and now ubuntu mate. Weirdly enough for me, with solusOS as well. i'm not a tec./linux savvy but i was always able to install different linux distros by myself but lately ... or its me that arrived at the end of my linux learning curve or i will need to replace soon my 11 year old x61s.
