Ubuntu Display settings showing unknown display

I'm quite new to Linux/Ubuntu, and just tried installing it on my machine.

After installing it, I could only see a purple screen, so I updated GRUB_CMDLINE_LINUX_DEFAULT with nomodeset in order to get some access to the UI. This allowed me to see the desktop, and log in, however in display settings, I can only see 'unknown display' and cannot change the resolution.

Would be handy if I could easily search the content of my documents such as PDF and DOC files. Preferably the files should be indexed to search faster.

So far I tried Recoll from the Snap store. However, the GUI seems a bit outdated.

Any recommendations?

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
