So I have a second CRT monitor plugged into the VGA port of my second graphics card. The monitor didn't show up in nvidia-settings so I found this thread:

forums.debian.net/viewtopic.php?t=126129

So I installed xserver-xorg-dev and now it shows up. So it seems like this package should be installed by sgfxi.


Unfortunately the monitor is still not detected by xrandr so my mouse cursor shows up when I move it off the right side of my first monitor, but there is nothing else that will display on the second monitor. I suppose I can try running sgfxi again and see if that makes a difference.

Too many unknowns here for me, can't force install of a different xorg package, that's not a thing sgfxi should do in my opinion, though it does appear there was a file in that developer xorg version that nvidia needs, but that actually sounds like an nvidia bug to be honest, might want to file an issue report on nvidia support forums because nvdiia has never, ever, required the developer version of xorg server to install itself or its tools correctly.

For some reason xrandr won't detect the second monitor, so the only way to use it is to use Xinerama, which is clunky and gives me graphical errors with some programs.

It seems like trying to use a second monitor on a second graphics card is just too much, it looks like I will have to get some kind of adapter.

Oh, you may have hit a corner case, I used xinerama for years with nvidia, but always with a 2 port graphics card, never 2 cards separate. There may be other ways around this issue, but I can't think of them offhand, but to me, anything that requires changing to the developer xorg server is probably an indication that there is a bug that should be filed to nvidia, they may have simply forgotten to test your scenario of 2 physical cards.
