What can I do to get radeon driver working on MacPro6,1 with dual AMD FirePro D300 GPUs

I'm trying to get Ubuntu 20.04 working on an older MacPro6,1 (cylinder/trashcan) with dual AMD FirePro D300 GPUs. The only way I get any screen output is if I nomodeset my grub config, effectively disabling the GPUs, if I understand correctly. I followed the info/wiki guide for RadeonDriver, e.g.:

MrA

Ubuntu 20.04

I have used the (ancient - 2006) Catalog management software Gwhere since Ubuntu 18. Recently, on starting, it had "forgotten" the directory where my data was stored and I had to open it every time I used the software.

So I thought I would uninstall (using Synaptic package manager) and reinstall the software using the downloaded .Deb file.

However, now the package installer tells me a Depe ...

Wifi trouble Ubuntu 20.04

I am running 64 bit Ubuntu 20.04.2 LTS on a Dell XPS 8700. I had wifi upon fresh installation but it stopped working upon reboot. I do not have an option to select the wifi menu. If I force it to show up, it will tell me no wifi adapter found.

I've been through several driver-related fixes with no luck so far. At the moment, I do not even have a driver in use for my wifi card (BCM43142).

How to enable secondary ethernet NIC card?

I recently set up a new Ubuntu 20.04 install on an old PC of mine. It's running some docker containers just fine. However, its installed ethernet NIC doesn't support 1000 Mbps speed. I'd like to be able to take advantage of my home network speed, so I bought this ethernet NIC. I'm new to hardware modification, but I believe I installed it correctly. I just plugged it into a PCIe port. I can see that  ...

How can I configure my Ubuntu laptop and set the blank screen and pc lockdown timers using the terminal?
in flag

I'm just lost. I found out that gsettings set org.gnome.desktop.session idle-delay lets me set the blank screen timer, but I can't find how to set the timer for the lockdown. The only solutions I find are on how to set it on or off.

I tried searching for gsettings commands but they are so many that I get lost. Also I couldn't find anything regarding setting a timer for the lockdown feature.

Delay when pressing backspace on only one keyboard model
ph flag

I am saddled with two MaxKeyboard Nighthawk X8 keyboards (USB mechanical). I can type with them fine, but I've found that, in Ubuntu (both 18.04 and 20.04, it seems), there is a delay whenever I switch from backspacing to typing, and vice/versa.

That is, If I type [a] [backspace] [b], there will be about a one second before the "a" disappears, and then another before the "b" apppears. If I do [a] ...

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.
