Nvidia 555 drivers causing no display on secondary monitor (lemmy.world)

Currently, if I upgrade to 555 drivers, my second monitor will not show a display despite it being detected by Plasma and xrandr. Additionally, if I do get past the log screen on wayland, my framerate/refresh rate is abysmal but not reported by xrandr. Unplugging the second monitor fixes the issue.

Sometimes, before login, I simply get a black screen/no signal which I've seen other post about but have not seen anything about second display not displaying.

Initially happened on EOS but swapped over to Bazzite and same issue. Reverting to the last 550 drivers and both monitors work fine.

I've tried setting nvidia kernel parameters for wayland and disabiling GSP firmware with no luck. Both monitors connected to the GPU. Issue on both x11 and wayland. Any input would be great.

UPDATE: Connecting the second display with DisplayPort instead of HDMI resolved the issue and I can log into wayland no problem with both functioning displays

Yeah, the black screen after logjn happens when both monitors are plugged in I've noticed. If I unplug the second monitor I can get into a wayland session fine but the moment I plug the second monitor in, the refresh rate tanks if the DE doesn't freeze first.

I'll try your suggestion and update the results after work.
