I think you would need to provide more detail to know what you have. Does it have a model number on it anywhere?

I cannot say that I have done extensive testing, but the Acer Swift 315-51G and Gigabyte Aero WV8 that I have both worked fine with Linux with zero prior research on my part. No issues with any drivers, even the SD card readers, although I have not checked the fingerprint sensor on the Acer. Maybe I have just been lucky.

Both have hybrid Nvidia graphics, though, and 10-series and prior hybrid graphics especially, as I understand, have issues with high idle power usage unless you manually disable the dGPU when not gaming, which I had to do using envycontrol and nearly doubled my battery life on both. I might avoid hybrid dGPUs and especially older ones unless you need that.

Used laptop-wise, I agree with others that a used business laptop like a Dell would probably be your best bet.

No problem! Mint XFCE sounds perfect to me.

That covers a pretty wide range of hardware, but that era would be around 2009-2015, give or take, so you would be looking at around Intel 1st gen to 6th gen most likely (Let’s be honest, there is nearly zero chance institutions would be using anything but Intel in that era). Pentium-branded CPUs from that time range, unfortunately, likely means low-end dual core CPUs with no hyperthreading, so 2C/2T, but I have run Linux on Core2-era machines without issue, so hopefully the CPU specs will be okay.

2-8GB of DDR3 RAM is most likely for that era, and as others point out, will be your biggest issue for running browsers. If the RAM is anything like the CPUs, I am assuming you will be looking at the lower end with 2-4GB depending on how old the oldest machines you have are, so I second the recommendation of maybe consolidating the RAM into fewer machines, or if you can get any kind of budget at all, DDR3 sticks on ebay are going to be dirt cheap. A quick look and I see bulk listings of 20x4GB sticks for $26.

In terms of distro/DE, I second anything with XFCE, but if you could bump them up to around 8GB RAM, then I think any DE would be feasible.

Hard drives shouldn’t be an issue I think, since desktop hard drives in the 320GB-1TB range would have been standard by then. Also, you are most likely outside of the “capacitor plague” era, so I would not expect motherboard issues, but you might open them up and dust them out so the fans aren’t struggling. Re-pasting the CPUs would also probably be a good idea, so maybe consider adding a couple $5 tubes of thermal paste to a possible budget. Polysynthetic thermal compounds which do not dry out easily would be preferable, and something like Arctic Silver 5 would also be an era-appropriate choice, lol.

I am not sure that I can really call what I did distrohopping, but

Mint w/ Cinnamon (several years ago on an old junker laptop and never ended up using it as a daily driver) -> Manjaro w/ KDE Plasma (daily driver for ~1 year) -> Arch w/ KDE Plasma (~2 years and counting).

I have also used Debian with no DE on a file server I made out of an old thin client PC and I have used Rasbian on a raspberry pi.

For most things it has not been an issue. Mice and keyboards have all been plug and play for me. Bluetooth headphones also work just fine for me. Setting up a printer was probably easier to do than in windows. My USB DAC, external hard drives, USB SD card readers, etc. have all been plug and play.

A persistent issue in Linux, however, are gaming peripherals. Anything which requires proprietary vendor software to configure RGB settings may be an issue. OpenRGB detects and allows me to configure the RGB on my Logitech G Pro Wireless Mouse, and I picked up a secondhand Drop CTRL mechanical keyboard which I was also able to reprogram in Linux, but broadly speaking any peripheral which requires dedicated software to program may or may not allow reconfiguration on a case-by-case basis. The last time I had to boot into Windows was to re-bind the key-map on an off-brand USB footswitch, which was a one-time fix and then it has worked fine since then. Similarly, the RGB on the keyboard in my Gigabyte laptop can only be configured from Windows.

On the laptop side, the main things to watch out for will be compatibility issues with fingerprint readers and certain oddball WiFi chipsets, but generally speaking my peripheral experience has been good.

I had a similar issue. I actually wrote myself a text document listing out all of the programs I generally use post-install and any additional setup I did, so that way whenever I am setting up a new system I can quickly refer back to it and save myself a lot of time over doing one-off installs as I run into them.

Welcome! Coming from Windows myself, I made the jump to Manjaro (It has certain issues and I do not recommend it), then to Arch less than a year after. I have been on Arch full time for around 2 years now. After the initial setup, I have found Arch to be pretty low-maintenance and no harder to maintain than any other distro, hardly requiring more than the occasional yay -Syu --noconfirm in the command line to update things. As someone with less computer knowledge than an IT professional, I think Arch’s reputation for being difficult is overblown IMO, and I suspect mostly due to intimidation from the more involved setup process prior to the availability of the install script.

I don’t know if you have any familiarity with Linux already from your work, but regardless of what distro you go with, I would go into it with a mindset that you are learning a new skill. Some things are simply done differently in Linux than Windows and will require getting used to, such as how drives work using mounting points rather than drive letters.

Realistically, setting things up for the first time often requires additional steps and may not “just work,” but when using my laptop and gaming desktop from day to day, it works just like any other OS. Gaming has been great for me generally, and the work Valve has done to improve game compatibility on Linux has been spectacular. Most Steam games do, in fact, “just work” for me.

In the 2-3 years I have been using Linux, I have rarely had things spontaneously break as many folks seem to worry about, or if I do it is because of companies not supporting their Linux communities, like Discord not pushing out updates on time, or major-event changes like the move to the Wayland graphical stack on KDE 6 which undid some of my desktop customization settings.
