AN update: managed to install the nvidia proprietary driver after fetching the most up to date version. With both xinerama and twinview enabled I get two perfectly usable screens. Problem now is that maximizing a window will maximize it across both screens.
Have posted in the KDE forums about my problem: https://forum.kde.org/viewtopic.php?f=6 … 40#p402040

I did not get lucky. I want to run KDE, not XFCE. I just added the update because it is IMO relevant - X does provide two screens, it's KDE that can't make use of both.

An update: if I start xfce instead of plasma, both monitors are used.

Obviously I tried this too. But in the KDE system settings, under "Display", I also only see a single display, and there are no buttons for detecting additional displays or configuring any additional display.
I had this working with the nvidia proprietary driver before, on the same hardware configuration, with Ubuntu 14.04 LTS, but that driver doesn't compile the kernel module on devuan ascii - seems a regression bug in the nvidia driver.

I have two identical graphics cards with two identical monitors, both connected to the graphics cards via VGA cables. Release is ascii.
X --conigure generates an xorg.conf which contains both graphics cards and both monitors, with the appropriate settings and X server layout, with different and correct BusID values for the two graphics cards.
However, when X starts (with KDE) I only see a black cross as a mouse cursor on the second monitor.
$ cat /etc/issue
Devuan GNU/Linux ascii \n \l
$ xrandr --listproviders
Providers: number : 1
Provider 0: id: 0x64 cap: 0x7, Source Output, Sink Output, Source Offload crtcs: 2 outputs: 3 associated providers: 0 name:nouveau
$ xrandr --listmonitors
Monitors: 1
0: +*VGA-1 1920/531x1080/299+0+0 VGA-1
How can I get the second monitor working/being used by X? What other info would help solve this problem?
