I did a reinstall of Linux Mint and after some problems with my system that required clearing CMOS, I finally got up and running.
I installed all of the main updates then ran the Drivers utility changing xserver-xorg-video-nouveau to nvidia-driver-550.

I have done this before without issues, but now I'm experiencing two issues!

1. My second monitor, which always worked with 550 now will not display. It has no display either from the NVidia card or from the CPU iGPU.
2. When I run Steam the screen opens but just displays whatever was showing behind it when it opens.

Suggestions on steps to troubleshoot would be helpful. The 550 driver never operated like this before.
 


Try a different kernel
 
1. Restart holding the Shift Key down which brings up the Grub Menu...the top Kernel is the one installed.

2. Select Advanced Options and select older Kernel...hit Enter...computer will boot to the Desktop...you now have the old Kernel installed.

3.Go to Update manager...View...Linux Kernels...Continue...you’ll see...5.19 and 5.15.

4. Go to 5.15...select Kernel 5.15.0-60 Active and click...Remove...once done the computer will boot to the previous Kernel...if you don’t remove Kernel 5.15.0-60 the computer will always boot to it.

NOTE: be sure the kernel you have changed to does what you want it to do
 
I kept the shift key held down all the way through the reboot process and nada. I just have Linux restarting.
I did bring up Update Manager and it shows my current version is 6.8.0.38 and there are several updates since then going up to 6.8.0.50! I clicked to install the latest kernel but rebooting did not use it even though it was installed. Probably need to update GRUB but shift just isn't doing it for me.

A little searching and I found ESC puts me into GRUB. But instead of just bringing up the menu, the menu pops up and then disappears and goes into the GRUB command line.

It's a matter of timing.....the instant you see the grub screen....tap the down arrow just once.......that should 'hold' that screen for you. You should see the kernel which is in use now.......followed by a previous kernel...tap the down arrow to highlight it, and then hit enter
When it boots to that kernel....test it out thoroughly to ensure your video problem has gone away and everything else is behaving itself.
When you are quite sure, go to update manager (either via menu or via the 'shield' icon down near the clock,,,,,click on view....then highlight the kernel which gave you trouble/....MAKE SURE YOU HAVE THE RIGHT ONE.......then click on Remove.

Reboot
