Nvidia + Nouveau Dual Monitor Woes

I just switched to Devuan from Gentoo and I'm having a bit of trouble getting my setup to pickup my second monitor. I'm using nouveau and I'd like to avoid switching to the proprietary drivers if at all possible. I thought maybe it was that Devuan was shipping with an older kernel, so I built and installed the latest linux sources but it's still a no-go.

Xrandr gives me this output:

xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
   1920x1080      0.00*
   1280x1024      0.00 
   1024x768       0.00 
   800x600        0.00 
   640x480        0.00

Even though there are 2 monitors connected: one via HDMI and the other via DVI. This setup worked fine for me on my last Gentoo install, as well as my last Arch setup OOTB. I've scoured the Internet in search of a solution, but none of the forum/blog/StackExchange posts have been able to even point me in the right direction.

Does anyone on here have a working nvidia+nouveau multi-head setup, and if so did you have any troubles achieving that? Think anyone here can point me in the right direction?

Thanks!!

Re: Nvidia + Nouveau Dual Monitor Woes

I have a dual-monitor setup with nvidia G210-something and nouveau. 1 VGA, 1 DVI, and also on a laptop with an added vga monitor. The desktop spans both monitors nicely, and it was easy to do.

Install lxrandr and run it.

Note: You might not see it in the applications menu, depending on what deskop you're using. You can edit /usr/share/applications/lxrandr.desktop to comment out the offiending line:

#NotShowIn=GNOME;KDE;XFCE;MATE;

And if you save the settings in xfce, you'll need to do the same with ~/.config/autostart/lxrandr-autostart.desktop

That's not it, lxrandr still only shows the one monitor
