How to make the screen size smaller

I have a broken screen in an L shape on my laptop, I want my screens resolution to change into the 75% of the screen that isn't broken so I can see the symbols down the bottom. Am I able to do this on Linux mint?

Custom Lateral Movement Detection Script—Feedback Wanted!

Hey everyone! I'm pretty new to cybersecurity, and I’ve been working on a custom project to tackle the challenge of detecting lateral movement within my lab environment. Based on some posts I’ve read about the frustration of catching attackers once they’re already inside the network, I wanted to create something that could help flag suspicious activity like RDP, SMB, or service account use—activities that are usually “normal” until they’re not.

Here’s what I’ve set up so far:

# My Stack:

* **Fail2ban, Clam AV, UFW** for basic protection (installed and configured to run on startup)
* **Suricata (NIDS)** on the service edge with Filebeat pushing logs to Security Onion
* **Security Onion** on the core server (ElasticSearch + Kibana)
* A **custom Python noscript** that pulls Suricata logs, queries ElasticSearch, and flags suspicious lateral movement patterns (like RDP, SMB, and service accounts)

# How it Works:

* Suricata logs network traffic (RDP, SMB, etc.) to `eve.json`.
* The noscript runs on my Raspberry Pi (or wherever Suricata is), fetching those logs.
* It then queries ElasticSearch (on Security Onion) to check for unusual patterns of activity.
* If suspicious activity is found, it compares it to a configurable threshold and logs it to `/var/log/lateral_movement_alerts.log`.

I’m still fine-tuning things like the detection rules and thresholds. The noscript is designed to be lightweight, customizable, and aims to reduce false positives by only alerting when activity crosses a certain threshold.

I’m looking for feedback on the following:

* Anyone else working on lateral movement detection? What’s your approach?
* Suggestions for improving thresholds or detection methods?
* Ideas for other tools or features to integrate into this type of noscript?

I’m hoping this can serve as a solid foundation for refining my understanding of SOC workflows and detection methods. Any thoughts, tips, or constructive criticism would be really appreciated! Thanks in advance.

Changing partitions via a liveboot usb, possible?

I just installed Truenas and realised that I cannot use the rest of the drive at all meaning I am wasting space.

Is it possible to use a ubuntu live USB or similar to run on the PC and edit the partitions on the harddrives?

This is not possible in truenas itself, even via shell.

Making "the switch" - A few Q's

I've been using Cachy OS on my gaming handheld, and loving it. I want to make the move on my main laptop. (RTX 4060 & i7 155H). But I have a few questions I really find solid answers for, so any help would be grand!


I use a Corsair Scimitar Elite mouse (the wireless one), idc about the RGB but is there an equivilant software that can handle the programmable buttons? Along with setting macros on them?

Generally, how is HDR support these days, I have an OLED with HDR and it just seems a waste to not use it as well as it can. Windows does a passing job, does linux? Appreciate this is probs a YMMV based on distro, but it would probs still be cachy OS, or maybe POP!

My GPU is a low TGP one, however it has a dynamic boost of 15W when it needs it, how is this handled on this side? Would it just use it when it needs it as it does now? Or is specific software required.

What is the most common application used for fan profiles?

Thanks!

Hi All,

I've written a WhatsApp Web Client for Linux called Sup. WhatSie is good in theory but it uses so much CPU that I decided to write one from scratch. Enjoy!

Why doesn't openSUSE get more love?

I don't see it recommended on reddit very often and I just want to understand why. Is it because reddit is more USA-centric and it's a German company?

With Tumbleweed and Leap, there's options for those who prefer more bleeding edge vs more stability. Plus there's excellent integration for both KDE and GNOME.

For what it's worth I've only used Tumbleweed KDE since switching to Linux about six months ago and have only needed to use terminal twice. Before that I was a windows user for my whole life.

GPU idle consumption decreases dramatically when nvidia-smi is run periodically

I have recently noticed that by running nvidia-smi periodically, about every 2 seconds, the power consumption of my notebook decreases by a lot. I am using Gnome Power Tracker, and I am seeing a decrease in consumption by about 10 W, sometimes even more. This happens when I am only using the integrated graphics. To reproduce just run nvidia-smi -l 2 or watch -n2 nvidia-smi, and after killing the process the power consumption will slowly creep up again. Just wanted to share, I have no idea if this is a misconfiguration on my part, or a bug in the nvidia-driver, which would be completely unheard of. /s

For those wondering, my config is: 4060 Laptop GPU, Ubuntu 24.04, Ryzen CPU and the latest 565.57 driver from the Ubuntu repo.
