Prevent Grub resolution reset during startup

I have set a custom Grub resolution, but around 3 seconds into the boot sequence the display reverts to the native screen resolution.

The screen is a small but high-resolution touchscreen (13", 3200×1800). I have added the following lines to /etc/default/grub before running sudo update-grub:

Avoid adding numbers to USB disks partition label/UUID when mount point exists under /media/user
lr flag

I'm using Ubuntu 23.04 and I'm assuming that Ubuntu is using autofs to auto mount. I'm unfamiliar with autofs configuration.

When I connect my labeled external drive(s) via usb, they automatically mount based on label in /media/user/label. However, if /media/user/label already exists (nothing mounted - empty directory), it mounts on /media/user/label1.

This is not what I want. If these old mount poin ...

Cannot upgrade because of updates, but cannot update because out of support

I want to upgrade my 18.04.6 LTS to the next LTS, but it won't let me because it thinks there are updates I should do first. However, these updates don't work and error with a "check your internet connection", I think because they are now only available as extended support.

22.04: Snap apps use SW emulation instead of GPU acceleration on AMD RDNA 3

Apps in Snap have no GPU acceleration with Radeon 7900 XTX. This causes very slow window redrawing in LibreOffice, and Google Maps in Firefox refuse to enable the 3D view.

I have the latest Mesa installed, which may be recommended for such a recent GPU, and indeed all non-snap apps do have GPU acceleration.

How do I install an arbitrary proprietary NVidia GPU driver on Ubuntu Studio 22.04?
in flag

I am trying to roll back my currently installed proprietary NVidia driver (v535) to an older version because I suspect the latest update causes problems with many Windows games played through Proton on Steam.

The driver manager in KDE does not seem to allow me to select another driver like I could in previous releases of Ubuntu Studio - the button to "Apply changes" is greyed out:

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.
