It shouldn't be the default is gnome with the LTS version.

Wasn't aware of that, thanks.

Can we look and see something that will define which is which?

Fresh install, sb on /, looks like it is.  I did a swapoff -a, then a swapon 
-a, that that helped I believe.

The next problem goes back to the EMC list, Its running

But the rtapi module cannot be found. so all of emc is out of commission.

Thanks Reinhold, now I'm back to swearing at a few gallons of Olympic Wood 
protector, trying to get it to jump out of the can, into an HVLP sprayer 
and thence onto a large quantity of native poplar I stacked up to look like  
a shadowbox style privacy fence after a 112mph wind took ours into the next 
drainage on June 24th.  Temps not to bad when I started about 9ish, but at 
noon the temps are looking to exceed the 85F they predicted for today.

Cheers, Gene
