SNMP on Linux stats without running the service.

Greetings,

Over 30 years ago (man I feel old), I had set up SNMP on Linux with Nagios and RRDTool.

While SNMP is hardly used anymore on Linux it had a lot of metrics that it collected, which was super useful for sending stats to either Nagios or RRDTool at the time.

Is there anything else out of the box that has a large set of monitors on Linux?

What are your favourite Linux out of the box metrics collection tools?

Best distros for older hardware?

So, I recently came into possession of some of my late girlfriend's things. Including an old Toshiba Satellite. I'm having trouble cracking into it, although using a live boot drive I managed to view at least the saved files. But, I'd still like to learn how to get into it eventually. Until that time, I've made a small project out of this little laptop. I've torn it down, wiped away some grime, repasted the chips, and swapped out the disk drive with my deceased gfs data on it for a sata SSD drive. It only has one ram slot filled so when I get the $10-20 I'll be getting another stick.

Anyway, I'm trying to push this little guy to perform it's absolute best it can. Maybe use it as a living room media PC. I have limited experience with Linux so I was wondering what distro people recommend? She used Lubutu and that's the live boot I tried using. It didn't seem the most intuitive to me but, what do I know haha?

The specs on the machine;
CPU: AMD Athlon Neo x2 L325
Graphics: Radeon HD 3200
RAM: Samsung 2GB 800mhz DDR2 SDRAM

The new drive is a 500GB Western Digital blue 3Dnand sata SSD.

I'd like to create a GUI that uses cryptsetup for creating, mounting, and unmounting luks containers

Using cryptsetup you can create luks containers, however running the individual commands is a bit cumbersome. This guide does a good job of explaining how to do it: https://michaelwaterman.nl/2025/10/14/secure-luks-container-on-linux/

But I think it would be helpful to have a GUI that simplifies this for you. I'd like to build one, it would be pretty similar to veracrypt but a much more light weight version that just uses the cryptsetup package and strictly just for managing luks containers.

What I plan to do is make a GTK app with C, because cryptsetup actually uses libcryptsetup, which is written in C. This way I can use the api directly.

Does anyone have any advice for this project? Please no obvious ones like "make sure it is safe and manages privileges correctly".

Safe boot

This is just a general discussion about a train of thought I have today. Yesterday i installed some software to try and disable extra keys on my mouse because i constantly press them by accident. After installing (and uninstalling) multiple packages i finally got it to work. Everything seemed fine until i rebooted.

Arch wouldn't boot, could not access tty's. The only lead i had were the changes i made the day before and my numlock flashing. I made a cachy-os livecd, arch-chroot into my arch install and step by step undid the changes i did the day before. After multiple uninstalls and reboots , checking pacman logs and bash history i finally booted in arch after removing libinput-config. Maybe because i don't know snapper, things could have been easier but the @ and "@home" etc directories didn't really make it simple.

I don't consider myself an expert, I guess i'm somewhat of an advanced amateur or something. But regular users who aren't tech savy probably would have given up and either reinstalled or go back to windows. What I did seems like such a small mistake and the consequences where so big compared to that.

So here is my thought, why don't we have a failsafe in linux in general for these kinds of things? If a livecd can be made that is roughly 2gb, surely there could be a safe mode like windows has that just boots the base system so users can troubleshoot? or some sort of a last 5 succesful boot snapshot system that can be easily accessed from the bootloader like windows system restore, leaving the files intact put disabling the programs/packages installed since the restore point? or even something easier to implement like a image containing the basics to run something like timeshift or snapper configured for your system since install, bootable from the bootloader to restore to an earlier snapshot?

The need for an extra pc/laptop to make a livecd to boot and fix your system would be almost non existent. Linux beginners would be safe, "unstable" bleeding edge systems would have a failsafe, and even expert linux users would save a lot of time.

For the people that ONLY use linux as there workstation and gaming device, how full is your storage?

I switched to arch linux like a year ago, when i used to use windows 11, over a 100+ gigs were used up windows and its crap without me installing much in it but since i switched to arch I have a complete workstation build+VMs+games(On a hard disk sure but the all the major software is on my SSD) and some other apps and noscripts that didnt exist on my windows install and its only 60 gigs.

So i am just curious how full are other peoples disks with a full setup that they use for work and gaming

Built-in Keyboard Totally Messed Up After Dual Booting Fedora KDE — Even BIOS Keys Are Wrong (ThinkPad P52)

Hey everyone,
I’m stuck with a super weird issue that started after I dual-booted Fedora KDE alongside Windows on my ThinkPad P52.

Here’s what happened step-by-step:

While installing Fedora KDE, my laptop keyboard started glitching.

After installation, I deleted the Fedora partition and even wiped the EFI entries related to KDE.

Right after that, my keyboard completely stopped working — even inside BIOS.

I can’t press Enter to get into BIOS, but an external USB keyboard works perfectly.

I thought it was a Windows issue, so I:

Reinstalled keyboard drivers

Fresh installed Windows

Even wiped everything and reinstalled Fedora KDE again
→ But still, no luck — keyboard still not working properly.



Things I’ve already tried:

Hard reset (removed battery, held power button 40–60 seconds)

BIOS update (done twice successfully — currently up to date)

Full clean reinstall of Windows and Fedora

Still the same issue, even outside OS environments


Now the weird part:
In BIOS Hardware Diagnostics, key mapping is completely wrong —

Pressing K shows as Alt

Arrow up/down register as Home and End
So the keyboard is technically working, but the embedded controller (EC) mapping seems corrupted.


People online say “your EC firmware is messed up,” but I have no clue how to fix or reflash EC firmware safely on a ThinkPad P52.

I’m totally stuck — BIOS and EC both updated, but built-in keyboard is unusable.


---

Has anyone faced something like this before?

How can I fix a corrupted EC firmware or reset keyboard mapping on a ThinkPad?

Any Lenovo tools or EC reflashing utilities that could help?


Any help would be massively appreciated 🙏

Specs:

ThinkPad P52

Xeon CPU, Quadro P2000 GPU

16GB RAM

Windows 11 / Fedora KDE (tested both)

AppImage apps fighting each other (Desktop integration)

I have 2 commercial apps that both run as AppImages. I'm on Ubuntu 24.04 LTS.

App #1 installs itself with Desktop Integration enabled (there's no way to turn it off).

App #2 runs without Desktop Integration but you can enable it via a setting in the app.

Both apps run perfectly. However, if I enable Desktop Integration on App #2, App #1 then reverts to having Desktop Integration turned off. The icon disappears from the application menu and the icon in the panel switches to the generic white box/gear AppImage icon.

Why is this happening? Is only one AppImage app allowed to be integrated into the desktop environment?

Drawing on Linux

Hello there. I plan on installing Linux into the next computer I get, I'm thinking either Mint or Pop.
I like to game, and I like to draw. I use a XP-Pen 15.6 Drawing Tablet and ClipStudioPaint for my program.
Are there any programs equivalent to the ClipStudioPaint that I can use for drawing? As far as I know, there are no branches or forks of CSP that was designed for Linux and I'd like to know which one to take a gander at before I go ahead and install. Look up some reviews and comparisons, y'know?


So far, it looks like Mint+Krita is the way to go. Thank you guys. Now to either construct or acquire a PC that I can rip Windows out of and install Mint unto.

FIPS & Google Authenticator Libpam

Has anyone run into trouble deploying TOTP using Google Authenticator (GA) on a FIPS enabled system?

I'm running a STIGed RHEL 9 box and I'm trying to use Google Authenticator for 2FA. I've run into a couple weird user account issues and my co-worker claims it's because Google authenticator can't run on a FIPS enabled machine. I successfully ran GA for a few days until a few user accounts were no longer accessible even after the account was unlocked and the password was reset.

I disabled GA and tried to dig through the auth logs to identify the issue and haven't found the source of the account issues. I'm trying to find out if anyone else has successfully used GA on a FIPS box so I can decide if I can eliminate it as the cause.

According to Red Hat, Xfce and Cinnamon are Linux distros

[https://www.redhat.com/en/topics/linux/whats-the-best-linux-distro-for-you](https://www.redhat.com/en/topics/linux/whats-the-best-linux-distro-for-you)

*There are many Linux distros, including:* 

* *Android*
* [*CentOS*](https://www.redhat.com/en/topics/linux/what-is-centos)
* *Debian*
* *Gentoo Linux*
* *Linux Mint*
* *Manjaro Linux*
* *Pop!\_OS*
* [*Red Hat® Enterprise Linux*](https://www.redhat.com/en/technologies/linux-platforms/enterprise-linux)
* *Ubuntu  (and all its versions: GNOME, Kubuntu—using KDE’s Plasma desktop, Ubuntu MATE, Xubuntu, and Lubuntu, to name a few)*

* [*Fedora Linux*](https://fedoraproject.org/)
* *Kali Linux*
* *Linux Lite*
* *openSUSE*
* *Raspberry Pi OS*
* *SUSE*
* *Xfce*

*Linux distros vary widely in what they do, how they do it, and how they’re supported. Some are designed as Linux desktop environments―such as Xfce, Raspberry Pi OS, and Cinnamon―while others support back-end IT systems like enterprise or web servers.*
