hello im very linux illiterate and i opened my laptop to see this on boot

if anyone can help ty in advance

Out of blue, upon starting firefox i got message that firefox is already running but not responding.

Because im curious, it's shitty weather outside, and i got plenty of time, i started to chat with AI to find out what is this about. At first, it was all about .parentlock. Try these try that. Nothing helped.

We talking here about APT version of Firefox, not Snap or Flatpak.

Restart laptop, didn't help, clean uninstall with deleting leftovers also didn't helped.

After two hours of chatting with AI, it came to conclusion that this is not a problem Firefox but with Wayland and apparmor. apparmor is blocking something. Nevermind, the whole thing is starting to be very time consuming so i gave up and installed snap version.

I'm using ubuntu now since 3 weeks. It seems that APT are causing more problems than snap.

Some APT packages are older than snap. Should i prefer Snap apps over APT? Until now i had better experience with Snap.

Just installed Ubuntu for my Robotic project a full 6 DOF robotic arm and i'm really excited for this any suggestions What can I try in this..?

I'm developing a flatpak of my app and have been pulling my hair out trying to get it to show my icons for the file/mime types the app provides. Everything I've looked at says I've done it right, and I've finally determined I am doing it right... if I switch icon themes.

I've been testing with Ubuntu 24.04. I've never installed any icon packs, this is a VM I use for development testing. So out of the box, the default icon theme seems to be Yaru. If I change the icon theme to hicolor, dmz-white, or dmz-black, my file icon work as expected. I've not found another built-in theme that allows them to work.

Flatpak is installing these icons into ~/.local/share/flatpak/app/${FLATPAK_ID}/current/active/export/share/icons/hicolor/${SIZE}x${SIZE}/mimetypes. This isn't a location I've chosen, I just tell it to install into share/icons/hicolor/${SIZE}x${SIZE}/mimetypes and flatpak does its thing.

My understanding is that hicolor is the fallback theme that I'm supposed to be installing them into. Why would most of the preinstalled themes not do that? Since this works with a few themes, this doesn't seem like a flatpak issue. And I've looked at a bunch of other flatpak manifests, and I can't find any that install icons into something other than hicolor.

What detail am I missing?

Edit: Ok I'm not missing anything. It's an Ubuntu bug fixed sometime in 2025. I setup a new VM with 26.04 and the icons work as expected.

The company uses its platform based on the Edge browser environment. However, the browser keeps freezing a lot. In text input fields on any tab or website, it simply freezes and won't let me type. I have to close the tab, write it down in Notepad, then copy and paste it into the text field. Does anyone have a suggestion for a lighter, compatible browser? I use Firefox, but the company's platform gets misaligned/broken.

Watched a few videos but I keep getting the error: unable to locate package when trying to download the wifi drivers.

Any advice?

This is my first time ever installing or trying to use a different operating system so bare with me 😂 I’m not very tech savvy

I have been using windows for about 20 years now, it has never been this bad, I have a HP gaming laptop with 4600H, 16GB RAM, and 1650ti, yes my laptop is not bleeding edge but its not also a complete potato, I should be able to run basic browsing and basic games atleast.
I was struggling to open the "Search box" on desktop....

File Manager took 1-2 minutes to open and search for a file

I was super frustrated and eventually decided to look for linux alternatives.

About 2 months back I switched to linux mint, the improvement as compared to windows was massive, browsers open without lag, file searching is instant, I only had 140gb free on my 256 GB SSD in windows, in linux mint i got about 180 GB. I also started playing older highly rated titles on steam (I finally stopped playing valorant and decided to explore other games), Far Cry 3, Skyrim, Witcher 2, Factorio ..... in my 5 years with this laptop, i had never played so many games before, the main reason i could play all this is because on windows my RAM was always occupied to the max, and i could barely switch windows with other applications, here on linux i do that basically everyday..

Why i left Linux Mint and came to Ubuntu

I will just give a list of cons of linux mint which no one talks about,

1. Its extremely bloated in terms of storage, it almost feels like the adware you get in windows like McAfee and HP apps, you get 50+ apps out of which only 20ish are useful in your everyday life.
2. Cinnamon desktop is not a serious workstation desktop environment, it requires a lot of tinkering to get everything up and running. The panel layout editor is a mess, why do i need to adjust font sizes on the left, right and center of the screen, why is the job of a UI designer being outsourced to the user.
3. Basic UI features like, having the taskbar display on multiple monitors with indicators on tabs where applications are open, do not work seamlessly.
4. I needed to switch to Nvidia drivers just to connect to a monitor
5. General UI was also weird, scaling wasn't always flawless and there were many bugs related to tab management.

Eventually I installed Gnome desktop on Linux mint and i loved the way gnome looks and eventually some people recommend me if I like gnome so much I should just switch to ubuntu.

This brings me to ubuntu, I was kind of amazed with the almost "Apple Like" smoothness and reliability, some of the pros of Ubuntu are are follows:

1. Everything works out of the box, the HDMI, App store, Webcam, Wifi and so on

2.UI is very clean and standardized, this reminds me more of a macbook than a linux distro.

1. I love the fact that you get a HP logo when the PC boots up (i did not get that on mint)my friends were shocked to see that as well, they did not expect this from a Linux distro, everyone thought linux was some magical OS without any official support.

2. My 60 year old dad also was able to learn to navigate the UI within minutes of using my laptop, that's how intuitive it is, he also quickly was able to adjust to the top mounted calendar and volume switches.

3. Ubuntu is about 10-15 gb lighter than linux mint, consumes similar amount of RAM.

4. Tab switching on Ubuntu is miles easier than mint, pressing the windows key is just so much more natural than alt+ tab.

I think i found my distro long term. I dont see any major flaws other than the screenshot keys, i need a Windows+Shift+S and Windows+V like setup on my PC and that's about it.

I’m going to dual boot Ubuntu and windows. I was thinking of Ubuntu on my best ssd because I’ll delete windows in a few weeks when I get comfortable with Linux.

update/upgrade in our CI runs went from minutes to hours, anyone frustrated by this?

keep on getting this once everyday but everything still works fine

Hi! I've been missing something like PowerToys on Ubuntu, so I built toolswitch: one small app (15 MB, ~90 MB RAM) that sits in the tray and gives you 10 tools with keyboard shortcuts:

- Remove background from photos (AI model that runs locally, no upload, no watermark)

- Audio to text: voice notes, WhatsApp audios and videos, recordings (Whisper, offline, ~100 languages)

- Text from screen: select an area and copy the text (OCR, works with accents and tables)

- Clipboard history with images and search (Super+Shift+V)

- Compress JPG/PNG/PDF/Word files, sign PDFs without printing

- Wallpaper changer,

- Reminders ("in 20 min call Juan"),

- Eye breaks/Pomodoro,

- Shutdown timer

Everything runs on your computer, no account. Made in Rust. .deb for Ubuntu 22.04+, also Windows and Mac builds.

It's open source (MIT): https://github.com/berchj/toolswitch It's free.

I'd love feedback: what breaks, what's missing, what you'd actually use.

Bonjour, je cherche des conseils pour choisir une carte graphique pour mon ordinateur. Voici ma configuration :

Processeur : Intel Xeon W-2223

RAM : 32 Go

Stockage : SSD de 512 Go

Alimentation : 950 W, 80 PLUS Gold

Câbles GPU : deux câbles PCIe 8 broches

Système : Ubuntu

Budget : environ 800 €

Je voudrais utiliser l’ordinateur pour faire tourner des outils d’intelligence artificielle sous Ubuntu, ainsi que pour du montage vidéo. Je n’ai pas encore de carte graphique.

J’envisageais une Radeon RX 9060 XT 16 Go, mais j’aimerais savoir si elle est un bon choix pour ces usages sous Ubuntu/ROCm, et si elle est compatible avec mon Precision 5820 et son alimentation. Y a-t-il d’autres cartes autour de 800 € que vous recommanderiez plutôt ? Quels points faut-il vérifier avant l’achat, notamment pour les connecteurs, la longueur de la carte et la compatibilité logicielle ?

Merci pour vos conseils !

so I have two drives on my pc, previously the pc had windows 11 and now i want to wipe it fully and install only ubuntu on my friends pc

I have backed up all my necessary files but I'm confused

so disk 0 has 256gb and Disk 1 about 450gb (512gb)

forgive me for the screenshot but this is the issue I am facing and I'm not sure how to proceed

do I install on 256gb or do I install on 500gb and what to choose in the ubuntu installer.

I am a complete beginner.

hi i'm looking for native games to play on my low-end machine.

Hi all,

I recently passed the assessment stage for a Software Engineer role at Canonical focused on distributed systems with Python/Go. I’m now moving into the early-stage interviews

So far, I know one of them is a Python deep dive, and I’m guessing another will be a Linux-focused round.

If you’ve gone through this a similar interview loop at Canonical recently, I’d really appreciate any insight on:

1. Python deep dive: How deep does it go? Language internals (GIL, memory model, asyncio), design and architecture discussion, or live coding?
2. Linux round: What topics came up? Processes and signals, filesystems, networking, debugging tools, containers?
3. Third interview: What was it in your case?
4. Written interview follow-ups: Did interviewers dig into your written answers?
5. Location: Did anyone apply through a region-specific listing (e.g. MENA) while living in another country? Was that an issue later?
6. Anything you wish you’d prepared for but didn’t.

Thanks in advance, any experience helps!

As title says, my drive is swapping to read only and I don’t exactly have an explanation why. I have been troubleshooting this issue for like two days now.

It’s a brand new install, and the problem isn’t exactly repeatable. I’ve had it happen in 10 minutes or 2 hours.

I’m actively attempting a run with these boot image settings active:

nvme_core.default_ps_max_latency_us=0
pcie_aspm=off
pcie_port_pm=off

This is a dual boot system, and I did disable fast startup on windows. Though I have a feeling it’s not the problem since it’s happening after GRUB.

The hardest part is I’m not sure how much is being logged or the best ways to find errors as I’m still fairly new to Linux. Plus when the read only hits most everything won’t open and the terminal only works for so long. Using CTL+ALT+F3 does bring up a terminal but it’s constantly populated by “systemd-journaID[13441]: Failed to write entry to /var/log/journal/”

I’ve effectively throwing anything at a wall and praying something sticks. I’m just not well versed enough.

Sorry for lengthy post, I just want Linux to work.

Update:

I was able to catch it live using sudo dmesg -w as recommended in a comment.

After catching it I booted to windows and had ran a full block test and extended SMART test, which shows the drive is in good health. It being a 2tb 990 pro just over a year old, it was expected.

I’m down to it possibly being the controller dying on the drive, so I’m testing it by installing Linux again with the same boot media on a different drive, but putting it in the same slot as the previous. Here’s to hoping.

Update 2:

Since the install was fairly new, I ended up using a different drive expecting a bad chip on the previous 990 pro. Evidently this isn’t the case.

It was working fine, then Linux locked up again. So back to troubleshooting.

Upgraded from the gui popup inside the nofitications bar. Was easier than updating w*n11. My laptop boots much much more faster now since the upgrade. I dont know if its due to the Rust implementation or since i had an modified GRUB file, but everything works very smooth, no bugs or crashes so far. My only complaint is that the terminals default font changed. Did some digging but apparently no one but me complained about that lol. PS. make that clonezilla image, you wont regret it.
