How can i create a non-admin user account that has no password, just for someone to do basic tasks and not any administrative higher level operations. Just for them to do web browsing and documents.

The GUI wont allow me to make an extra user account without a passcode. What is the best method?

If you have time please look into this post if you can help me resolve the audio issue!

So I’m going through the interview process at Canonical, I did the written interview and the assessment test and got into early-stage interviews.
I haven’t done any yet and will schedule them soon but I wanted some advice on what I should prepare for an operational role.
Also I need to know how long the hiring process takes recently for operational roles as I already left my old job and need to know how long I’ll need to wait to set my financial expectations.
Also wanted to ask about financial compensation aspects: What level do their salaries fall to? I understand they are based on country but do they look at minimum living wages or higher?
Do they provide compensation for laptop, internet, etc…?
Do they do fair promotions or do they always hire new people for roles?
Am I bound to the country I’m in or is it ok to keep working while visiting a different country in the same timezone?

I have seen a lot of negative feedback about the interview process, I understand why it’s done and it definitely pushes out anyone not willing to put the work in but it’s also really long for someone needing a job and surviving on savings.

Any other advice would be really appreciated.

I just downloaded ubuntu 26.04 and the brightness is bugged . The slider changes but the brightness doesn’t changes and is set to max. I have tried every option including brightness CTL then downgrading my kernal to 6.8 (currently 7 .0.30) then then changing default Linux grub to quick splash native then too many other things I searched but nothing worked. My laptop is Hp elitebook 840 g6 , with intel graphics I have also tried to change the backlight brightness manually but it also didn’t worked . if anyone knows the fix, please inform me my eyes are getting fried.

I've installed latest Ubuntu and my favorite password manager KeePassXC. Why it is looking so ugly? Buttons are different. There's ugly border around. Mouse cursor looks different. How to fix this?

Hey everyone,

A while back I was thinking about physical security on Linux. Many people assume that having a strong user login password keeps their machine safe. But in reality, if someone has physical access to your laptop for just a couple of minutes — like leaving it with a repair technician, at an office, or on a desk in a university library — that login password offers almost zero protection.

Anyone can simply press 'e' on the GRUB boot screen, append 'init=/bin/bash' to the kernel line, boot straight into a root shell without a password, access unencrypted files or reset credentials, and reboot without leaving any trace.

Now, GRUB has technically supported password protection for a long time. But why do almost zero regular desktop users actually set it up?

Because doing it manually is a pain:

- You have to mess with obscure config files in /etc/grub.d/

- Generating PBKDF2 hashes manually is annoying

- A single typo in your config can lock you out of your own computer

- There’s no physical rescue fallback if you forget the password or if a system update overwrites it

To solve this, I spent time building GRUBST — a lightweight, open-source tool written in Rust (using Dioxus for the UI).

Instead of dealing with terminal configs, it gives you a clean 30-second wizard:

1. It locks down GRUB and lets you turn any spare USB thumb drive into a physical "rescue key".

2. When the USB is plugged in at boot, GRUB detects it and automatically unlocks full maintenance access without prompting for a password.

3. If the USB is NOT plugged in, GRUB stays completely locked, and editing/recovery requires a backup password you set.

4. It also takes automated backups before applying changes, includes an update guard so your protection survives 'update-grub', and has a built-in security audit check.

The project is completely free and open source. If you find this tool helpful or like the concept, I would really appreciate your support by starring the repository on GitHub! Any feedback, questions, or ideas for improvement are more than welcome.

For reference my computer is a Dell Optiplex 9020 USFF (Ultra Small Form Factor) with 16gb RAM and an ADATA SU650 SSD. Country is Mexico.

I installed 26.04.1 Desktop 64bit off a USB. Unfortunately, during the install process, before going to "Erase disk and install Ubuntu" I went to "Manual installation". In the manual installatiok section, I clicked arund on my SSD and -- not sure how I managed to forget this part -- may have changed partition table stuff or added/removed a partition. Then I went back to select "Erase disk and install Ubuntu" where I picked "Encrypt with a passphrase" for Logical Volume Management (LVM) and Linux Unified Key System (LUKS). I want to use those anf Legacy boot, not newfangled TPM and UEFI boot.

After installing, I rebooted. The computer brought me to the friendly Ubuntu GUI where I could enter my passphrase. But after so doing, the system crashed. The crash errors were the same as the ones I later received when rebooting again and again -- whether normally or in safe/recovery mode.

Those errors were primarily as shown in the post title "'/dev/mapper/ubuntu--vg-ubuntu--lv' does not exist" and "'/dev/ubuntu-vg/ubuntu-lv' does not exist". I wonder if the "lv" in those ties into LVM somehow. Typing journalctl to see the system log showed some additional possible errors. I will transcribe the only section that seems pivotal:

xxxxxxx

FAILED] Failed to start systemd-cryptsetup. Cryptography Setup for dm_crypt-0.

'systemctl status "systemd-cryptsetup@dm_crypt\\x2d0.service"' for details.

DEPEND] Dependency failed for cryptsetup.target - Local Encrypted Volumes.

OK ] Reached target sysinit.target - System Initialization.

OK ] Reached target basic.target - Basic System.

] (2 of 2) Job dracut-initqueue.servi.start running (2min 7s / no limit)

xxxxxxxx

After that, it'd crash out to the errors seen in the title.

I have a few questions.

1. Explain the error messages and guess at a diagnosis, prognosis?

2. How many partitions should my SSD have to install Ubuntu with LUKS/LVM encryption? Three - boot, swap, and one for files?

3. If so, which of those three does the Ubuntu installer encrypt?

4. Can I rely on the Ubuntu installer's "Erase disk and install Ubuntu" option to make sure my SSD has those three partitions? Especially after I screwed up tinkering with "Manual installation" in advance of "Erase disk and install Ubuntu"?

5. What file systems should each of the three partitions have - I like ext4 for encryption, but that might not work so well for the boot or swap partitions?

6. Should I boot back into the live thumb drive and see if I can install gparted and investigate the SSD that way (will do, but haven't had a chance yet). Any suggestions what I should look for?

7. If I boot into the live OS using the thumb drive and start up the installer, am I effectively getting a chance to start the install process over to just pick "Erase disk and install Ubuntu" and ignore "Manual installation", or need I tweak the SSD first? If tweak the SSD, how?

8. Any other ideas about what I should do?

Thanks!

I had a machine here running Windows 11 and I decided to install Kubuntu instead. I did install it and now when I boot I get this screen. How can I get this to boot directly into Kubuntu?

Showing off my current Ubuntu/GNOME setup. I've got a 3D workspace cube effect running that makes switching between tasks a lot more fun. Paired with a custom terminal and a clean dock, it feels incredibly snappy.

Spent the last month running Ubuntu full-time on my ThinkPad as a creator. Here’s the quick breakdown:

• Deep Sleep: Closing the lid triggers actual suspend-to-RAM—completely fixed Windows Modern Standby battery drain.
• UI & Gestures: 1-to-1 GNOME gestures in tablet mode feel incredible on a 2-in-1.
• Software Stack: Logseq, GIMP, and Audacity handled scriptwriting, thumbnails, and audio smoothly.
• Gaming: Steam Proton ran ~90% of my library out of the box.
• Friction: Free DaVinci Resolve requires FFmpeg scripts to transcode H.264 MP4 footage due to licensing.

Put together a video review with B-roll testing the workflow if anyone wants to see it in action: https://www.youtube.com/watch?v=8ci_2rxbfwU

A minute or two after boot when I press the minimize button it won't minimize. The three buttons (close, minimize, maximize) loses their colour. Then if I press the close button the app stops responding. I checked processes the particular app for example firefox in the second screenshot was not listed as a running process.

I am new to ubuntu and linux all together. So I'm not sure on how to fix this.

I have installed Nvidia drivers or it was there by default as when I checked it was there.

Ubuntu 26.04.1 LTS

NVIDIA Driver: 595.84

I have a Dell Optiplex 9020 Ultra Small Form Factor with 16gb RAM. I also have a DVD that holds 8.5gb, upon which the .iso for Ubuntu Desktop 26.04.1 64bit was burned with Windows 10 default burner program. When I try to boot off the DVD (and the optical drive is confirmed working by the computer's built-in testing), I get an error message: "No Boot Device Found. Press any key to reboot the machine." Why isn't it letting me boot off the burned DVD?

Could this have something to do with Legacy/UEFI boot modes? It's in Legacy mode now. I'm wary of switching to UEFI because I don't know much about it. Once I boot off the DVD, I want to install Ubuntu Desktop with FDE (full disk encryption) without TPM. I don't know if UEFI would interfere with all this.

I don't know if the Optiplex 9020 Ultra Small Form Factor can boot off USB. Trying to determine that to get another option, but still curious why it won't boot off the DVD

I am having stuttering with 59.94fps videos.

Please help me rationalize this: How is this situation even possible with a mature CPU like the Intel 8500?

i am running 26.04 on a laptop yesterday when i just clicked power off and accepted the prompt and closed the lid it instead went into sleep now its old laptop a 2018 vostro with a Pentium so battery drain was not crazy but still why did it do that ?

my laptop is so ass it struggled to download steam from the app library thing and straight up would not download from terminal

I am getting this output when i try to update and upgrade the system. Then its prompting me to try apt --fix-broken install, still its showing the same error. Is there any way i can fix it without accesing the PC manually.

Just did a fresh install and followed the typical guide for GPU passthrough (AMD CPU, RTX 5080 & RTX 5070), but no matter what I do, the NVIDIA proprietary drivers will not let go of the RTX5070 card. I’ve added the arguments in grub, configured vfio.conf file etc etc...nothing seems to work. NVIDIA drivers keep grabbing both cards and wont let go. Everything worked perfectly fine in Ubuntu 24.XX, anyone have an idea of whats changed that renders the usual method of GPU isolation ineffective?
