Re: 2 tft 2 workspaces how ?
It doesn't look so bad, I am confused at why it would not work.
I use a similar setup and I get two screens.
Does nvidia-settings show a separate hostname:0.0 and hostname:0.1 screen?
Maybe you have the correct configuration at X server level, but your window manager is trying to fool you.
I use KDE and what I get is two separate screens each with their own taskbar, icons, etc.
