Ubuntu 21.10 crashes randomly with "read-only filesystem" errors
sd flag

My Lenovo Thinkpad X1 Yoga (20JD) with a Samsung 970 EVO Plus keeps randomly freezing, and eventually shows a black screen with journalctl and other errors. I have to hold the power button to shut it down. I'm dual booting Windows 10 and Ubuntu 21.10, if that helps.

Here are some of the errors that it shows (in no particular order, they're all scrolling so fast I can't see it that well)

Opening a directory in a mounted disk uses a different icon

My home directory is mounted in a different disk than my os.

The consequence of this is when I open the file explorer it uses the icon for the disk explorer:

Instead of the file icon:

Is there a way to make it use the later rather than the first?

This is what /etc/fstab/ looks like:

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.
