Nouveau - Aug 2022 - Ubuntu 22.04 system freeze on nVidia GT218 [GeForce 210]

When I upgraded to Ubuntu 22.04 LTS from 20.04 LTS, it removed my 
proprietary nvidia drivers and installed nouveau.? When I run graphical 
apps like Chrome, Firefox, especially both, or even gnucash, it freezes, 
sometimes after a time seems to unfreeze, and then refreezes.? Other 
users have switched back to the nvidia proprietary driver, but I have 
not figured out how.? I had similar problems on 20.04 LTS and figured 
out how to go to nvidia, but it seems like the option is missing in 
22.04.? As a bonus for going to nvidia, BOINC apps were able to use my 
GPU.? I have a nVidia GT218 [GeForce 210] GPU, apparently part of the 
nvidia 340 family of drivers.
