Linux dual head

Because I am too poor to get a 4 to 8 ddr5 video card I use two video cards a nvidia 430 (2 gb) and a 1 gb 9500. I use them in a dual dvi mode and these are the operating systems that allow ne to do it

Opensuse using gnome desktop
Oracle Linux using gnome desktop
Linux Mint Cinnamon

The ones which do not:
Mageia

Ubuntu appears to but then crashes.

I think that Linux Mint Cinnamon 18.1 is one of the best linux distros and oprnsuse 42.2 is one of the best linux distros for server in gnome mode.

Ways to connect KDE to wireless

Recently there have been many newer editions of operating systems. Here are a few of the best features to look for. The KDE is coming forth with plasma 5. This has been slower when compared to cinnamon and the 26 other desktop environments which I highly recommend. Slant gives a review of KDE as being unstable and kdeinit locks up.

Should you need to work with KDE these following commands are invaluable: 

killall plasma-desktop

kstart plasma-desktop

On the network manager side it is a disaster. Wicd is a command oriented alternative which seems to conflict. On opensuse there is xinitd. On debian based systems because one can use CENI.
