Ubuntu 22.04, HDMI works, but display port fails

cn flag

There are three external monitors connecting to Dell latitude 7430 using a docking station with an onboard intel GPU. The monitors can connect with HDMI cables, but fail when using the Display port. The issue is that the dock station only supports one HDMI cable port, and I have to connect other monitors using the display ports.

Any idea why and how to fix this?

The issue was resolved after installing the latest Dell driver. Maybe it helps others.

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.
