Format USB from Files in Ubuntu

Ok, why can I not format a USB drive from Files/Nautilus anymore? For clarity, I have not used Ubuntu (non server) myself for a while now, but after installing for a customer I have confirmed on another machine that the "format" option fails with a disk is busy option. Yes, I can close and use Disks, but this is not something users should need to figure out. I can help out, but then why is the option still there?

Starting a Linux community on Amino.

I don't know if guys have heard of amino, but i just got in there for the purpose of helping my girlfriend on her community on Amino, and while I was browsing through the available community, i couldn't find anything for a Linux community, so i decided to take the initiative of starting one. I don't know if it would be popular or not. But i would like to hear your thoughts on if it's a good idea, and I you want here's a link to that community on Amino, if you want you can join and contribute to the community, it's in a very early stage of development, but I am sure if I get the support I would be able to make it better. And any views on this would be appreciated.
Here's the link to the community: http://aminoapps.com/c/HailLinux

A story to tell

There was yet another thread about virtues of text editors, and I was reminded of when I first got into using Linux.

Some years ago, a friend of mine, Bob, helped me get RH 4 installed. I had no idea about any of this, but my friend is damn smart. At this time, video drivers were not as available, and with each update, I had to recompile the kernel. Bob held my hand through this a few times until I got how to do it. But in one instance, when we were working on a machine with a fresh kernel, he realized that we had not installed pico or nano or vi or anything.

Dude wrote an X11.conf by writing it line by line at the CL, from scratch, using echo and >> to append each line to X11.conf and point it to the appropriate driver. It worked. He just pictured the file in his head and added to it line by line.

Bob, you brilliant magnificent bastard.

I would love to hear if there are others with stories that just impress unforgettably. I'll share them with Bob, he's still a close friend.

Linux Format magazine final issue is July 2025 No 329

Linux format bows out with its 329th issue number dated July 2025, just issued this weekend. Suddenly and without announcement, I read on page one that it's the final issue (while also beiing their 25th Anniversary issue, a fact that was mentioned in issue 328).

Old fashioned for some, maybe, but I did enjoy the off-screen monthly read.

Thanks and good luck!

Just switched back to X11 again. But I feel like Wayland is so close now.

I am running void linux and my desktop with an nvidia gpu. For the past few years I have tried intermittently to switch to wayland with disastrous results.

No screensharing, electron apps won't work at all. And if you use xwayland they would be blurry, have artifacts and glitches all over the place.

I switched last week again and this was the longest I have come to keeping it. But sadly, I had to switch back again.

I was using niri as my compositor. It's pretty cool

####What works that wouldn't before:
1. Screen Sharing. (The desktop portals are a godsend), I don't have to use gnome just to be able to screenshare.
2. Electron Apps, at least start as long as you set that Ozone environment variable thingy.
3. Most apps just work now without having to go through the hassle of some tweaks and fixes.

#### What's still problematic
1. For the apps that do work, the electron apps are still laggy
2. I use WezTerm as my terminal emulator and am very happy with it on Xorg, but on Wayland it has a noticeable input lag. Other ones that I have tried such as GhosTTY and RIO have this weird startup delay.
3. I use Emacs and the gtk3 build does not work on wayland, so I switch to pgtk build, which is quite laggy. (Starting to notice a patter here)


#### Why I am going back to Xorg
1. It just works for me (tm)
2. I don't really have a 4k monitor or a dual monitor setup or whatever, I don't really care about fractional scaling (I don't even know what that is)
3. Apart from the points mentioned in 2, the only other reason why people push for wayland seems to be security and that xorg is unmaintained. But that doesn't really matter for me, currently my Xorg setup works better than what I can achieve using wayland and nobody has stolen my secrets yet (fingers crossed).
4. People are going to be like, but it's not Wayland's fault, it's Nvidia. Sure, but what can I do, I will make sure to by AMD next time, but for now I have to make it work, somehow

I will definitely go back at some point mainly for Niri which is an amazing window manager, I have fallen in love. But for now, back to Xorg and BSPWM my beloved.

Open Source LLM?

Is there any demand for a truly free, open-source LLM—a real alternative to ChatGPT designed specifically for Linux users? Could such a project become a reality, perhaps as a community-hosted server, a local setup, or a shared resource to help more people benefit from AI in the Linux ecosystem? I’d also like to know if something like this already exists—has anyone heard of similar efforts?

Firmware-Level USB Trap Logs (IMC / MediaTek 13d3:3563) — Full Forensics Archive

I'm investigating abnormal USB firmware behavior on an ASUS TUF A16 system (MediaTek 13d3:3563 Bluetooth chip by IMC Networks).

Using a custom `udev` rule + logging noscript, I captured full forensic snapshots every time the device connected — even when unauthorized.

✅ Each `.tar.gz` contains:

* `dmesg`, `lsusb`, `udevadm` output
* USB denoscriptor dumps (`xxd`, `binwalk`, strings)
* Hex-ready files for **Ghidra** reverse engineering
* Auto-archived + timestamped

📁 **All capture sessions are archived here**:
🔗 [Dropbox Folder – Forensics-Finding-Fubar-Firmware](https://www.dropbox.com/scl/fo/lownlke9lih5kofzt2b90/AJIJhqdQkAH1n_2FsMkcL8Y?rlkey=2fysyipqmsmgo1xa77crxy5n2&st=h65gxezq&dl=0)

I'm hoping to get second opinions on:

* Whether these logs show signs of rootkit, emulation, or hidden interface triggers
* Any anomalies in USB enumeration, interfaces, or control transfers
* Advice on digging deeper (firmware extraction, reverse shell detection, etc.)

Tools used: bash, DropBox API, `udev`, `xxd`, `binwalk`, and Ghidra.

If anyone is interested in helping reverse-engineer what’s going on here or validating what I’ve caught — I’d be incredibly grateful.

Let’s figure this out 🔍

Anybody here encountered a distro called Chakra back in the day?

I found this comment in a thread in a 9 years old post:

>As far as I know there is no distro-agnostic long time stable way of deployng third party applications with the current centralized distro methodology. All solution approaches step out the distro model: either by decoupling system from apps (like chakra) or by containerization (like portable apps or docker)

Anybody knows what this particular individual was trying to say about Chakra?

Super handy Fish function - Arch Linux - Find packages that satisfy nonexistent commands and libraries

This fish function atomatically finds the right package to satisfy the command or library that you just tried to use, for example typing:

libopenal.so

or

lolcat

would find the package and prompt to install it using yay (or pacman if you configure it).

Success getting Gaomon PD1560 to work on Kubuntu

I had success getting my Gaomon PD1560 drawing tablet work on Kubuntu 24.04 without a lot of hassle! I thought I'd make a post about my experience with it in case anyone else needs to know how I got mine to work as well.

I first had to make sure HDMI for my tablet was plugged into my computer's CPU instead of GPU. This probably will vary depending on CPU/GPU, but HDMI plugged into GPU does not work on Linux, as far as I can tell. (I made another post on a different subreddit with more details if anyone is curious)
I was able to install drivers through Steam using Proton, but it seems that Kubuntu's compatability with Wacom allows this to be a bit easier. I don't have to make sure the drivers are on for the tablet to work.
I did have to remap the pen display using xinput and it isn't perfect, but still very usable.
PEN PRESSURE WORKS!!!!!!!

I've heard success from other people also making their Gaomon tablets work on Linux, and I wanted to add to that- it's very possible!!
