Nividia driver for an old card

I have an old NVIDIA GeForce GT 430 card and it works on my desktop with the Nouveau driver. However, this driver is very limited.


I am using Linux Mint 22 and I can't install the 390 driver of Nividia (Fermi-based GPUs) which will have hardware acceleration for my card. I have tried many ways but it didn't work for me. This driver is working on Mint 21 but I don't want to downgrade my kernel.


Is there anyone who succeed to install it on Linux kernel 6.8? If so, how can can I do it?
Thanks a lot for your help!

System76 vs Framework vs Tuxedo

I am looking to get a linux laptop in the future and after reading and watching many reviews about these three laptops, I am very undecided still. They all have good things, bad things, I don't know what to choose. I am aware that this is a highly subjective matter, but still, what is your take? Which would you say is best?

I Want to to learn cyber security ( beginner) . What's the best linux book you recommend for me as a part of the cyber security learning process .


I know linux is essential for this domain but there is plenty of books from beginners to professional, but I'm kinda lost which level is required to be good at cyber security.

If any linux certificates recommended too .
Thanks

Can someone suggest a boot CDROM for an old PC?

I need something that ships with smartctl.

Long story short, I've been using NoblePup32 and it's great, but smartctl is not on it and I need to monitor the SSD wear-leveling on this old Windows 98 PC that I upgraded.

The only other image I tried was the old 32 bit version of System Recovery which tried to run a GUI and it was not pretty.

I need something that boots to a command prompt as quickly and simply as possible.

Thanks

copy / paste paths into nano?

Hi everyone,

sometimes a config file points to a file. I use nano for editing and navigating with bash (no gui). What is the best way to copy a path into nano?

I always have to remember the path to the file I need and then switch to nano and enter the path manually... Is there any way to do this smarter?

Best Laptop for Linux + Software Engineer in 2025?

Guys, I need the best laptop available for being a digital nomad pretty much, my workload can be pretty heavy/demanding as well. I know this question has been asked before, but just want to hear from fellow developers/linux users.

I've settled on endeavorOS for the past few years, the following laptops are the ones I think I would like the best.

- Macbook Pro M4 Pro

- Thinkpad X1 Carbon Gen 12

- Dell XPS 13 (2024)



Now my concerns are:

- I know mac has always been difficult with putting linux on it, i had an older 2013 macbook pro which I put asahi on, not sure how that works these days for the newer installations.

- Not a really big fan of dell tbh, the xps is probably the only product I like from them.

Thats pretty much it actually, what is the feasibility of putting linux on the m4 pro, also im not too big in the apple eco system, so no iphone or watch or anything. I'd much prefer the mac tbh, but I have always loved the t470 and t490 thinkpads, so an x1 carbon is also a nice choice.

Just want to hear some opinions/advice/suggestions from you guys, even if you want to tell me my choices are shit and have other ideas :D. Thanks!

PS: I think the most important aspects for me would be the keyboard, battery life, and raw computing power.

Linux phone with keyboard?

Sorry for asking this.

I really want a GNU/Linux phone to run some of the apps I enjoy, but it only makes sense with a handheld attached physical keyboard, because otherwise the screen space is very small. Maybe what I want doesn't exist and the way is to use an SBC or something. It is OK if the phone runs only with Halium.

Basically, all I need is a Nokia N900 with more RAM.

Please do not tell me about Graphene or whatever here. I don't want only privacy but also freedom. Also, I don't need any of my current Android apps, in any case I can take an Android with me if I see I really need them.

From what I know Planet Computers and Fxtec are not actually shipping and are probably forgotten.

And if such a phone doesn't exist, why doesn't it?

terminal multiplexor scrolling

hi everyone,

I have been using tmux for a while but have never gotten mouse scrolling to work. I know I can use the keyboard, but I'd like to be able to use both. I understand that set -g mouse on is meant to make this work but it doesn't.

is there a multiplexor out there where this just works?

Built an “Everything”-like instant file search tool for Linux Btrfs. I would love the feedbacks & contributions!!

I’m a first-year CSE student who was finding a file search tool and found nothing close to "everything" and I’ve always admired how **“Everything” on Windows** can search files almost instantly, but on Linux I found `find` too slow and `locate` often out of date. So I asked myself , "why not make one own" .

I ended up building a **CLI tool for Btrfs** that:

* Reads **Btrfs metadata directly** instead of crawling directories.
* Uses **inotify** for real-time updates to the database.
* **Prewarms cache** so searches feel nearly instant (I’m getting \~1–60ms lookups).
* Is **easy to install** – clone the repo, run some noscripts , and you’re good to go.
* Currently CLI-only but I’d like to add a GUI later. even a flow launcher type UI in future.

This is my first serious project that feels “real” (compared to my old noscripts), so I’d love:

1. Honest feedback on performance and usability.
2. Suggestions for new features or improvements.
3. Contributions from anyone who loves file systems or Python!

GitHub repo: [https://github.com/Lord-Deepankar/Coding/tree/main/btrfs-lightning-search](https://github.com/Lord-Deepankar/Coding/tree/main/btrfs-lightning-search)

CHECK THE "NEW UPDATE" SECTION IN [README.md](http://README.md) , IT HAS THE MORE OPTIMIZED FILE SEARCHER TOOL. WHICH GIVES 1-60ms lookups , VERSION TAG v1.0.1 !!!!!!!!

The github release section has .tar and zip files of the same, but they have the old search program , so that's a bit slow, 60-200ms , i'll release a new package soon with new search program.

I know I’m still at the start of my journey, and there are way smarter devs out here who are crazy talented, but I’m excited to share this and hopefully get some advice to make it better. Thanks for reading!

Comparison Table:

|Feature|`find`|`locate`|`Everything` (Windows)|**Your Tool** (Linux Btrfs)|
|:-|:-|:-|:-|:-|
||||||
|**Search Speed**|Slow (disk I/O every time)|Fast (uses prebuilt DB)|Instant (<10ms)|Instant (1–60ms after cache warm-up)|
|**Index Type**|None (walks directory tree)|Database updated periodically|NTFS Master File Table (MFT)|Btrfs metadata table + in-memory DB|
|**Real-time Updates**|❌ No|❌ No|✅ Yes|✅ Yes (via inotify)|
|**Freshness**|Always up-to-date (but slow)|Can be outdated (daily updates)|Always up-to-date|Always up-to-date|
|**Disk Usage**|Low (no index)|Moderate (database file)|Low|Low (optimized DB)|
|**Dependencies**|None|`mlocateplocate` or|Windows only|Python, SQLite, Btrfs system|
|**Ease of Use**|CLI only|CLI only|GUI|CLI (GUI planned)|

finding and disabling damaged ram addresses

my dad gave me his old ThinkPad that he stopped using because broke and some of the ram addresses cause the OS to crash, he told me that Linux has a way to disable those addresses if I can find them, so if I could get a little help with finding them that would be great.

the ram in question is 16gbs of soldered ram, there may be an easier way of just completely blocking all the soldered ram instead of just segments and that would work great for me too.

all my ram tests I've run say it's fine though so my dad might have been wrong about what caused the issue. it's caused one blue screen in windows, don't remember the code though and so far Ubuntu 25.04 has stayed stable.

rtask 0.91-beta - select 1-N cpu(s) from cpu topology to run a linux command or pin a process

I have 2 Minisforum MS-01 servers that use Intel CPU's with big.LITTLE architecture comprising of performance P-core and energy efficent E-core CPU cores. Both run fedora linux 42.


They run a bespoke image database with various plug-ins to social media channels
and I noticed that selecting an image, resizing said image and generating a caption
text was taking anywhere from 4 to 14 seconds. Our billing system also had large
variations in how long it took to run a query and generate report (6 to 12 seconds).


Found time and took a look at what was causing such variations in runtimes.

For my set of applications it came down to:

1. the overhead of scheduling between p-core or e-core cpu's

2. a big pool of p-core cpu's also caused scheduling issues


With that in mind I created a little utility to easily:

1. list cpu topology and list which cpu's are p-core and e-core

2. manually specify 1-N cpu's to use to run a command or aleady running process

3. automatically generate a list of cpu's based on socket, numa, core and cpu

4. allow realtime scheduling and fast I/O priority scheduling


Using the rtask utility I was able to get faster and more consistent runtimes:

1. select+resize image with caption text: 1.5 vs. 4-14 seconds

2. generating our standard billing report: 0.6 vs. 6-12 seconds


Download: [https://lightaffaire.com/code/linux/rtask](https://lightaffaire.com/code/linux/rtask) (+ chmod 755 rtask)

```
$ rtask --help

Usage: rtask [options]
--pid process pin process
--run command run command
--time-it time the --run command

--realtime set real-time scheduling (can starve system)
--fast-io set if --run/--pid is I/O-bound (disk heavy)

manually assign cpu list (--list-cpu):
--cpu-list list rtask --cpu-list [1,2,N|1-N]

automatically generate cpu list:
--cpu-socket num cpu socket (default: 0)
--cpu-numa num cpu numa (default: 0)
--cpu-core num cpu type (default: .*)
--cpu-type text cpu type [p-core|e-core] (default: p-core)
--num-cpu num number of --cpu-type cpu's to assign (default: 4)
--all-p-core assign all p-core cpu's to --run|--pid
--all-e-core assign all e-core cpu's to --run|--pid
--randomize randomize cpu list

list cpu/scheduler info:
--list-cpu list cpu p-core and e-core layout
--list-raw list cpu raw values [maxmhz,mhz,socket,numa,core,cpu]
--list-topology list topology tree [socket->numa->core->cpu]
--list-scheduler list kernel scheduler

--system-info system info
--help help

Examples:
$ rtask --list-cpu

$ rtask --list-topology

$ rtask --list-scheduler

automatically select 4 p-core cpu's and run the command
$ rtask --run "COMMAND"

manually select 2 p-core cpu's and time the command
$ rtask --time-it --cpu-list 1,2 --run "COMMAND"

automatically select 2 random e-core cpu's and run the command
$ rtask --cpu-type e-core --random --num-cpu 2 --run "COMMAND"

automatically select all e-core cpu's for the running process
$ rtask --all-e-core --pid PID

fastest set of options to run the command
$ rtask --all-p-core --realtime --fast-io --run "COMMAND"
```

Lets check the number and speed of P-core and E-core cpu's on a MS-01:
