GPU accelaration ubuntu 18.04

[Luke]

Use MPV media player - that has accelerated video playack for files up-to 4K@30FPS.

You can also use SMplayer with 1080p files. For SMPlayer you just need to specify settings in the config.

Thanks, Luke!

smplayer works without lagging though it seems grainy.  I was using vlc.

Still can't get stellarium to work, though it worked right after I installed it.

Still works in the default debian build, but opens a small box and just sits there in Ubuntu/mate 18.04.

I was trying to get wine to work, when I started having video issues.  If I have to, I'll reflash the SD back to the original image and then reinstall stuff (carefully).

Thanks again!

Experiment and have fun
