I write this topic, just to sharing what is running now on my desktop.
I did not know Mate graphics desktop was that great.
I have mate Ubuntu, to this is is third edition, on my main desktop.
It is my experience, it is the best long up time, without hang.
Also it carries a back-up and restore utility can place back-up date on local drive, a partition, network drive (samba)...
it has a strong built-in encryption whole disk utility.
thank every one for reading.
