My name is Rick I have been using Linux on and off for about 10+ years. I started with Linux in about 1996. Back then Linux was on a floppy disk. When the boot-able CD-ROM came it was a joy to use.
I use Ubuntu Mate all the time. Right now I am using UM 15.10 and I have a laptop that has UM 16.04 A1 -> B2. This machine has another hdd attached with another OS. I thinking of putting UM 16.04 on it but have not yet decided. B2 does work with this machine. It has a GT240 video card. When I changed setting to Marco GPU it has what kind of looks like salt and pepper or sprinkles that appear every now and then. I did not try the Nvidia driver as I was running a live cd.
Thanks for listening.
