Monitors not being recognized 23.04 Thunderbolt 4 Dock NVIDIA 525

Problem

Upgraded from 20.04 LTS to 23.04 now: The main monitor on the laptop does not work. Only one monitor of three works on Thunderbolt 4 dock. I am using two DisplayPort and one HDMI on the dock, all terminating into HDMI on the monitors. I can get one additional monitor to work if I use the HDMI port on the laptop.

I was using the NVIDIA 530 drivers before but for some reason, 23.04 does not have them, so now using 525.

Goal

Get all three external monitors to work. Also, having a laptop screen would be nice.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
