Comment 2 for bug 1392743

I made an account just to comment here.

Nvidia requires GPU's to be assigned to an Xserver for it to be possible to manually control clocks, voltage and fan speed. This is done in nvidia-settings after adding the "Coolbits" option to the xorg.conf file, and adding the device to an Xscreen.

This bug therefore makes it impossible to use these options together with Cinnamon. (that's not in fallback mode)

I've linked/attached my current xorg.conf file, the xorg log and the xsession error log. (/etc/X11/xorg.conf, /var/log/Xorg.0.log, ~/.xsession-errors)

I've spent hours tring to figure this out, and tried all possible combinations in my xorg.log file. I will happily provide more information or testing if anyone is willing to help out with this.

System:
- 1x Nvidia GTX 1080
- 2x Nvidia GTX 780
- Nvidia driver 370.28 from nvidia.com
- Linux Mint 18
- Cinnamon 3.0.7
