How to reinstall missing libraries to repair ubuntu 20.10 after stupidly purging some libraries and shutting down
in flag

I'm fairly new to linux and I was trying ti install samba in order to use to share files with a Windows 10 qemu/kvm virtual machine. Samba though wouldn't be installed and I couldn't figure out why. Searching through the forum I stupidly followed some guy's instructions where he would autoremove some library but with the --purge flag.

Almost immediately I realized that wasn't a wise move since it ...

Set resolution 2560x1080 Wayland update 21.04
cn flag

I recently updated from Ubuntu 20.04 Groovy Gorilla to Ubuntu 21.04 hirsute. With 20.04 I was able to set the custom resolution of my LG ULTRAWIDE monitor to 2560x1080 using xrandr because my session type was Xorg. The 21.04 update was not successful but that is a seperate case. Once I fixed the botched update issue, I logged in and certain things were missing and uninstalled but most importantly the r ...

SATA SSD not detected after installing Xubuntu 18.04
ng flag

I have an NVMe M.2 256 GB drive and a 240 GB SATA SSD with Windows on the NVMe M.2 drive. I tried to install Xubuntu 18.04 on the SATA SSD.

The installation was successful, but after rebooting, the SATA SSD is not detected by BIOS. I tried clearing CMOS and tested the SSD on another PC. The SATA SSD was not detected on the other system too.

ky flag

I have just purchased a new IdeaPad 5 14ALC05 w/o OS and installed Ubuntu 21.04. So far so good.

The problem is that suspend appears not to work. No matter wether the power cord is connected or not, when I close the lid and wait for ca. 20 s or when I use the desktop menu / Power Off / Suspend function, the screen turns black and the power LED starts slowly pulsing, so I take it the system is sus ...

How can I install MegaSync on Ubuntu 20.04? Software Center doesn't work
br flag

My software installer does nothing in Ubuntu 20.04.

I downloaded a deb package and clicked on it, but nothing happened. I installed Chrome with the terminal by finding a command line that downloaded and installed the package through the terminal.

Now I want MegaSync and can't find a command line. If it allows me to download a package and it's a software installer, is it wrong to assume that it shoul ...

What is the correct way to automatically configure promisc mode in Ubuntu 18.04? (Vagrant)
fr flag

To configure a VPN gateway in Ubuntu 16.04 (Vagrant) I used to use /etc/rc.local to enable promisc mode, but this is no longer an option in Ubuntu 18.04:

        /sbin/ifconfig {{ vpn_nic }} up
        /sbin/ifconfig {{ vpn_nic }} promisc

What would the correct way of doing this be in Ubuntu 18 now?

Further info: The vagrant configuration which I don't believe needs to change was set to:

Firefox 89.0 on Ubuntu - poor performance
cn flag

I've clean install of Ubuntu 20.04.2 LTS, and Firefox 89.0.

Performance of Firefox is very poor, you can see that even when scrolling simple pages, it looks like there are just 10 FPS.

I know that FF does not support hardware acceleration for my config but I think that my specs should still allow it to work fluent.

Any recommendation what should I do to improve FF performance?

Dell XPS 13 9310 sleep mode issues
ru flag

It is known (from several forums) that the Dell XPS 13 9130 does not support "deep sleep". Whether this issue can be fixed (i.e. enabling this option) by code a new BIOS version is not clear to me.

Anyhow, with Dell BIOS v 2.2.0 and UBUNTU 20.04, I have this annoying problem that might be fixed directly:

When entering sleep mode with WIFI on, I get a huge battery power loss (up to 20% power gone within 4 ...

It has been asked almost 4 years ago in this question, and no one found a solution. does anyone knows if this option is still missing? perhaps a kwin script could do the trick?

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.
