First off, want to thank you for your help, generix. Couldn’t have got it to work without out (and I’ve put in literally 100s of hours trying to get this to work before w/o any success). Secondly, we’re only 90% there. With both GPUs active w/ the 6 monitor under Mint Kfce, I had periodic UI freezes every 40-60 seconds that lasted 3-4 seconds each. Because of this, and knowing Cinnamon is even more of a headache when it comes to graphic driver issues (and I wanted to see if I could get this working from a fresh complete install)… I completely blew out my installation and attempted to install Mint Cinnamon from scratch, getting this to work there also. I did, successfully (going to put a step-by-step write-up how using our discussions); however, it’s still plagued by the periodic freezing (which only becomes present after the ‘modprobe nouveau’ which activates all the screens to come on). On reboot, this is the only command I have to enter to get it working once I initially get things setup (it’ll reset lightdm for me, etc. and take me back to a login screen where all six monitors work and are arranged properly). Not sure what is causing it, as I couldn’t find anything in the logs. There are still some minor glitches too, as sometimes objects being drawn flicker, etc. So, I’d say it’s a step in the right direction… but not usable quite yet.
I do have a question for you, generix. Under the ‘xrandr --listproviders’, I have the following for my 1080 TI:
Provider 0: id: 0x1b9 cap: 0x1, Source Output crtcs: 4 outputs: 7 associated providers: 0 name:NVIDIA-0
It says it has 7 outputs associated? How is that? I’m assuming the ‘Source Output crtcs’ are the actual number of ports on the back (3xdisplayport+1xHDMI)? Are each displayport capable of handling two outputs w/ the right adapter (only way I can get to 7 from 4 physical ports)?
Anyhow… I’ll provide the xorg.conf and log once I get back home this evening. Again, appreciate ya’.
