How to prevent random logouts on Nvidia GeForce GPU (Nouveau)?

Question

I recently replaced my old AMD Radeon video card with a GeForce GTX 650 in a PC with an AMD CPU.

The card seems to work fine, however, since the replacement, Xubuntu 18.04 gets seemingly random logouts every couple of hours. The screens turn black and a few seconds later, I find myself back at the greeter, having to log back in with all programs closed/crashed.

This did not happen once before and this also happened on a live system (Ubuntu MATE), so I assume the video card is definitely the culprit in the equation.

The error log apparently shows some problems with bamfdaemon at the timecode of the logout:

Is there anything that can be done about this or might this be an issue with the hardware itself? (Currently using Xubuntu 18.04 on Kernel 5.3)
