I have a computer that is not quite powerful enough to run my flight simulators, but which is still quite capable. I tried to sell it for close to what I bought it for, after using it maybe 50 hours, but the stink of "used" was on it, so I only got low ball offers for the system as a whole. Selling the individual components would be better but take substantially more effort. Instead, after finding an absurdly good 64 GB RAM deal ($150 for DDR4, in early December, crazy), I decided to use it to educate myself on some work-adjacent science simulation capabilities, putting it at home to avoid the feeling like I'm doing work (and also so I can install nonsense on it if I want).

I settled on Pop! OS, after finding out it has the best NVIDIA GPU support of the .deb Linux family, and installed 22.04 on it last month. After a standard "oops I messed something up on a new-to-me Linux distro, might as well wipe it," I reset the bios to see if it fixed things, then loaded 24.04 on a live USB and ran the update at POST.

24.04 made some very big changes to Pop! OS, which I won't list, other than one that puzzles me. After installing, I ran Geekbench 6 to benchmark it, and I found out my system CPU performance was about 33% down from the prior benchmark. I rationalized this as being due to no XMP being on, and tried to enter BIOS on boot...but Pop24 refused to enter BIOS, and my motherboard didn't even POST? But it would load into Pop24 without issue? So I was stuck without a way to tune my system. I eventually removed the SSD, hard wiped it on a separate device, and reinstalled Pop22, whereafter I was able to enter BIOS and enable XMP. Performance was restored, and even better than ever.

My question...why is Pop24 different? I tried to disable fastboot. I tried to have it use systemctl to reboot into settings. I tried everything I could find online. The best guess I have is something to do with UEFI? But I have no clue. I'm not really a computer guy, I just futz around, and I don't know what I'm doing.

Is it just me, or is it weird that every terminal starts at the top-left? After three commands, your prompt stays at the bottom of the screen for the rest of the session anyway.

I added this to my fish_greeting last month. (You could add something similar to .bashrc / .zshrc):

printf "\033[$LINES;1H"

If you want to print a status line or two after this then subtract the number of extra lines:

printf '\033[%s;1H' (math $LINES - 1)
cat /proc/loadavg

It might take some getting used to but it feels a lot more natural. When opening a new window or pane, the prompt is always closer to the previous one so my eyes don't need to move as much.

It's a small subtle thing but I think it is an improvement. Return to teletype.

I recently set up some public computers with Ubuntu at a hackerspace. People kept logging into their Gmail etc. and forgetting to log out. For their own benefit I changed the computers to use overlayfs so on reboot all changes from the base filesystem (Ubuntu 24.04 + packages + updates) are lost. I'm looking for tips on configuration. Keep in mind that because our users tend to be fairly technical I am not attempting to outright prevent changes, just prevent them by default.

Here are the current details:

• The machines have a wallpaper warning users that all changes are wiped on reboot
• The normal automatic update system is disabled (updates through it won't persist)
• I install updates and reboot on a cronjob at 5am every day (this uses overlayroot-chroot)
• The overlay is implemented as an encrypted filesystem on a separate partition, with the key generated on boot and held in memory
• Documentation is taped to the desktop computer itself educating users on how to make persistent changes

I've started to look into getting a 3D printer mainly for printing minis and terrain for TTRPGs. For the aficionado and print quality the best printer type seem to be resin based printers, but I don't think I'd be able to deal with the toxic fumes in a safe manner. As such I've settled on looking at filament based printers and I don't really need super high fidelity prints.

I need one that works well with Linux and preferably OSS. I am willing to pay for closed source software (or OSS) if it runs on well on Linux. So if you know of any software that is easy to get started with I'd be happy to hear about it. If you know of any models or makes that I should avoid I'd also appreciate a heads up!

Any other advice for someone just getting started with 3D printing?

I use a Mac for work, Linux for my personal machine, and the same mouse between the two. I’m accustomed to the dpi/acceleration on Mac, so when I switch to my PC at the end of the day there are slight inaccuracies with the pointer. My wrist compensates to cover the gaps and I develop wrist strain after short periods of use.

Does anyone know how to make the Linux mouse dpi/acceleration as close to identical as possible with my Mac?

Hello!

I recently reworked my setup such that I have my drive which holds the operating systems (dual boot of Windows 11 and Linux Mint Cinnamon) and another drive which holds all my actual data. This is my first dive into trying to move to Linux as my daily driver but I'm noticing some performance issues.

The first thing I noticed is that transfer speeds are much less than expected. Copying a large file within my data drive I get about 300MB/s on Linux, which is pretty slow for M.2 drives- I get about 10x that speed doing the exact same operation on Windows. I could be okay with this but I also noticed that some video files, like the 4K mp4s off my phone, are virtually unplayable. They'll run at maybe 1fps and/or bog down the UI so much I cant even use the seek. This is the case in both the default media player and VLC. These same files play with no issue on Windows.

I suspect the reason for all this stems from my data drive being NTFS, though my file system and Linux knowledge is pretty weak so this is just a theory. Any ideas / best practices that might help me here?

Pretty much the title. I want to move away from OEM 1st party controllers due to quality and inevitable joystick drift. I have an 8bitdo Ultimate, but it's not working for me on CachyOS.

Anyone else have experience with good quality controllers on Linux? The Flydigi Vader Pro 5 caught my attention, and I am a pretty competitive person for certain games (mainly Halo 3 and Halo Infinite), and like tight controls for platformers and souls-like games as well.

Edit: I primarily used my controllers wireless, especially on the living room PC. I am more okay with wired on my personal computer.

Found a solution!!

Fixes for 8BitDo controllers running under Linux.

sudo mkdir /etc/udev/rules.d

sudo nano /etc/udev/rules.d/99-8bitdo-xinput.rules

ACTION=="add", ATTRS{idVendor}=="2dc8", ATTRS{idProduct}=="3106", RUN+="/sbin/modprobe xpad", RUN+="/bin/sh -c 'echo 2dc8 3106 > /sys/bus/usb/drivers/xpad/new_id'"

sudo udevadm control --reload

Change Product ID according to your controller:

Product ID 8BitDo Ultimate/Ultimate C 2,4Ghz: 3106

Product ID 8BitDo Ultimate 3-Mode 2,4Ghz: 200f / alternate Product ID: 201b

Product ID 8BitDo Ultimate 2C 2,4GhZ: 310a

I've had my Steam Deck a few months so I'm comfortable getting around. That said, it could do a lot that it isn't. Partly because the default desktop experience is so barebones and has kinda bad ergonomics.

I know there's emulation and such that I'd be interested in. I'm a linux nerd so don't be shy. I'd say the main thing I'm looking for is for the Desktop mode to be more of like a "default to Couch Mode: unlocked, but can go to a (nice) desktop if need be". I really like the idea of playing my GOG games, emulators, etc all in one menu that's ergonomic to controller. I have a file server handy as well, anything good to do with that in conjunction?

Besides that, what good/cool uses have you found?

Hi all! I'm someone who has ADHD/Autism spectrum issues and am dealing with problems related to executive function. To the point, I'm asking for help with a specific idea of better managing getting things done.

What I'd like is a job tracker / ticket management system that would make it easy for me to keep track of all the different individual to-do items (I.E. jobs / tickets) that I have, keep notes on what I've already done, and have a separate notes section for 'this is what still needs to be done on this item'.

Currently I have this information kind of scattered through different areas / folders. Calendar, work documentation folders, personal notes, etc...

Needs:

1. Free (open source is nice but not explicitly required). I don't want to add another expense to my balance sheet.
2. Is user-friendly enough to save me more effort than it costs. I am a long-time tech so the bar on this one is reasonably low.
3. A GUI. If there are CLI / command line interface programs that would not be convenient for me, I work much more efficiently when I work visually. If I need to install by CLI that's not a problem, just the daily use of the program should be graphical and not command-line text.
4. (EDITED IN): Locally installed. I want to stay away from adding more company-hosted services which can change / become paid only / otherwise easily undergo Enshittification. If it is locally installed software, I can always decline to update or install a new version.

Nice to haves:

1. A tracker that gives datestamps for when I put in more information so I can easily know when I last picked up that task.
2. A priority system so I can have it automatically sort to top for stuff that needs doing sooner vs long-term projects.
3. Some kind of 'tagging' system which would allow me to tag things like 'personal' or 'work' or 'parts orders' which I could then use a search or sort function to look at only items tagged that way.

My main desktop is Linux Mint 21.3 Cinnamon in case anyone needs that detail. That is the computer I want to install the ticketing system on.

I've done some searching so far but I'm hoping that by laying out exactly what I'm trying to do with it someone here will have specific advice. My search results so far have found people recommending projects for others who have different use-cases or needs than me.
