New Test candidate is Fedora Workstation 29, running kernel 4.18.16.
Fedora is the open source, and test software for and owned by Redhat Linux.
I liked the live load so well, I installed it on the hard drive.
Fedora Workstation comes with the Gnome Desktop, which is my current desktop of choice.
Fedora workstation , is very similar to Ubuntu Gnome.
Fedora uses Yum as the package manager, Ubuntu uses Apt as the package manager.
Fedora workstation 29 can be downloaded for free from here.
Burn it to a USB stick or burn it to a DVD, and try in live mode.
That allows you to try it on your computer, without loading it to the hard drive.
Great OS software, and I grade it an A.
Here's some screenshots of Fedora 29 Workstation!
