Ubuntu 20.04 does not detect external monitor through HDMI/DisplayPort adapter
th flag

I am trying to set up an external monitor to my laptop (Lenovo ThinkPad E14 Gen2). The monitor doesn't have an HDMI port, so I am using an HDMI/Display port adapter, but Ubuntu doesn't seem to detect the monitor. When I use the HDMI cable without the adapter (i.e. with my TV) it works perfectly.

This is the output of xrandr:

lsof shows that .xsession-errors' deleted files chews up all disk space
cn flag

I configured a cronjob that truncates the ~/.xsession-errors file because it was chewing up all disk space. This keeps the file smaller than 500K. The disk space is still being filled.

lsof +L1 | grep deleted shows many instances of xsession-errors deleted items that will fill all disk space. Only a reboot seems to clear this.

What could be the cause?

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.
