I believe I've encountered a bug in cinnamon and I thought it's worth documenting it. In short, cinnamon DE crashes when run in headless mode. I downloaded and installed the latest Linux mint about 1-2 months ago so I have relatively recent software versions.
The long description is this. I have a PC which has an integrated graphics card on the motherboard (MB) but also a dedicated Nvidia graphics card with Nvidia drivers (v535). The PC was set up as a desktop PC attached to a single monitor plugged into the dedicated graphics card. This setup is fully working and there were no issues to report.
I converted the PC to a remote machine - in this set up, the PC is plugged into power and ethernet but has no monitor attached and I remote to it from my laptop using nomachine. Initially, this resulted in a small resolution display (e.g. 640x480). I found out that I need to have a "headless" setup as per:
https://virtualgl.org/Documentation/HeadlessNV
The resulting xorg.conf is below:

This seemed to work - when I remoted to the display the login screen was full resolution. Unfortumately, almost immediately after typing my password on the login page, cinnamon crashes. As far as I can tell, it is the DE or the windows manager that crashes because I can still right-click and get a menu and start a terminal and then start applications. The windows don't have the minimize/maximize/close buttons though. I looked into '.xsession-errors' and I saw that cinnamon crashes because it can't find a monitor as show in the log below:

It looks like it crashes because it cannot find a monitor. However, a monitor is defined in the xorg.conf file.
I installed xfce4 and this works without any problems and so does MATE. Cinnamon also works for a few seconds at login after which point it crashes.
First, I'd like to report the problem and second, is there a way to stop it crashing? I'd like to continue using cinnamon.
