I am having a hard time following everything happening here. What is all this about hotspots and your neighbor's router? Do you not own a wifi router? Most wifi routers will also have ethernet connections on the back. I apologize for not understanding. Edit: I am guessing by "I do not have a lan line" you mean that you do not have a working internet connection at all at home? I am confused as to how you intend to run a server permanently over a phone hotspot.

My one thought is: have you gone into your router and reserved a static internal IP on your LAN? (e.g. 192.168.0.##)? Often servers and things will lose communication if their internal IP changes and your devices cannot find them.

Also, if you are porting out onto the public internet, are you using something like a dynamic DNS so that your devices can route to your public IP? your public IP will be constantly changing, so you need some way for your devices to find it.

1. I don't know much about gnome, sorry!

2. The main issues to watch out for are driver issues related to certain peripherals like fingerprint scanners, SD card readers, and certain oddball wifi chipsets. Hybrid graphics with both integrated CPU graphics and a dedicated GPU can lead to poor battery life in some systems such as many gaming laptops. In my experience, Linux runs fine on every laptop which I have tried it with, including 2 with hybrid Nvidia graphics. I'm also 2 for 2 on SD card readers and 3/3 on wifi cards as well, despite no prior research on my part.

3. Arch Linux sounds like it would be the closest to what you are describing. Or try out one of the more preconfigured versions like Endeavour OS or Arcolinux, as the install process for Arch can be a bit involved for someone new to Linux.

4. Usually not difficult so long as something is not a hard dependency for some other piece of software. Running something as root in Linux is as simple as typing "sudo" before a command and entering your root password

5. No. Per the above, elevated user privileges are permitted as a normal part of using Linux and do not require you to hack or bypass the OS's security mechanisms like in Android or iOS.

6. If you install more than one, depending on your login manager it is usually as simple as a dropdown menu to select which DE you want to use when logging in.

7. Wayland is a window manager/GUI system used in Linux. It has been getting a lot of discussion lately because the Linux community is gradually shifting from the longstanding but now unmaintained X11 system to Wayland. You probably don't need to worry about it.

Are there mice which are not supported in Linux? Everything I have used from a junky unbranded wireless mouse to a high end Logitech gaming mouse have all been plug and play for me. Even the RGB settings can be configured in openRGB.

Comfort should always be an important factor in a mouse for any OS, I would think. In terms of build quality, I have had the rubber on some mice start to degrade over time, but that is about it. Even the cheapest mice that are hard plastic can last for decades with no problem.

I would say that switchable DPI would be a must-have feature for me with modern displays. As someone with a 4k monitor, some junky office mice do not have enough sensitivity for me on high resolution monitors even with the setting cranked to max in the settings menu.

For wireless mice, I prefer AA battery mice over USB rechargeable mice, but that is a matter of personal preference. If my mouse battery dies in a AA mouse, I can swap the rechargeable NiMH battery in a minute and continue using it. However, if a USB rechargeable mouse is dead, I either have to use it on a tether for a while or remember to constantly keep recharging it. Also, having an integrated li-ion battery will give any mouse a limited lifespan unless you are willing to open up and solder in a new battery when it wears out, whereas I have some AA-powered mice which are going strong probably a decade later, so long I have had to open them up and re-solder them with new microswitches instead of new batteries.

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.

Oh no, I've been caught, haha. Good memory!

To my defense, the story seemed relevant to OP's question, and the post that it was originally in has been deleted, apparently.

What is your use case? For me, something like a fileserver which I am mainly SSH-ing into anyway, I may not install a DE at all, but if this is going to be a general-use desktop, I see no reason not to install the DE right from the beginning, and selecting a DE will be part of the install process of most Linux distros, or some distros have different install disk images that you can download with any given DE which it supports.

If you are very concerned about keeping your system lean and want full control of what gets installed, you might want to look up guides for installing Arch Linux. The initial setup process is more involved than other distros, but once you have it installed, I think its reputation for being difficult is overblown.

As others have mentioned, secondhand laptops and surplus business laptops are very affordable and probably better value for the money than a chromebook. My understanding is that drivers for things like fingerprint sensors, SD card readers, or oddball Wi-Fi chipsets can be issues to watch out for. But personally I don't care about the fingerprint sensor and only the Wi-Fi would be a major issue to me.

A couple years ago now I picked up a used Acer Swift with 8th gen intel and a dent in the back lid for something like $200 to use as my "throw in a backpack for travel" laptop, and it has been working great. In retrospect, I would have looked for something with 16GB of RAM or upgradeable RAM (8GB soldered to the motherboard, ugh), but aside from that minor gripe it has been a good experience.

I have been daily driving Linux for a couple years now after finally jumping ship on Windows. Here are a few of my thoughts:

• it is important to make the distinction between the distro and the desktop environment, which is a big part of how the UI will look and feel. Many of these DEs such as KDE Plasma, XFCE, and GNOME will be common across many distros. I might do some research on which DE you like the look of. I personally have used KDE the most and that is what I prefer, but all of them are valid options.
• Coming from Windows, I would go into this with the mindset that you are learning a new skill. Depending on how advanced you are with windows, you will find that some things in Linux are simply done differently to how they are in Windows, and you will get used to them over time. Understanding how the file system works with mounting points rather than drive letters was probably a big one for me, but now that I have a grasp of it, it makes total sense to me and I really like it.
• It will also be learning a skill in terms of occasionally debugging problems. As much as I would like to report that I've never had a problem, I have occasionally run into things which required a bit of setup at first or didn't "just work" right out of the box. I know that probably sounds scary, but it really isn't with the right mindset, and there are tons of resources online and people willing to help.

It depends on a few factors. Stock laptop experience with no power management software will likely result in poor battery life. You will need some kind of power management like TLP, auto-cpufreq, or powertop to handle your laptop's power management settings.

Second is the entire issue of dedicated GPUs and hybrid graphics in laptops, which can be a real issue for Linux laptops. In my own laptop with a dGPU, I am reasonably certain that the dGPU simply never turns off. I have yet to figure out a working solution for this, and so my battery life seems to be consistently worse than the Windows install dual-booted with it on the same machine.

I am not sure if we are discussing hibernation for encrypted systems only, and I do not know what special provisions are needed for that, but for anyone curious, here is what I do on my own machine (not encrypted) per my own notes for setting up Arch, with a swap file rather than a swap partition, and rEFInd as the boot manager (the same kernel params could probably be used in Grub too, though):

• create a file at sudo nano /etc/tmpfiles.d/hibernation_image_size.conf (copy paste the template from https://wiki.archlinux.org/title/Power_management/Suspend_and_hibernate)
• if you made your swap file large enough (~1.2x ram size or greater), set the argument value to your amount of ram, e.g. 32GB= 34359738368
• after a reboot, you can verify this with cat /sys/power/image_size
• findmnt -no UUID -T /swapfile to get swapfile UUID
• filefrag -v /swapfile | awk '$1=="0:" {print substr($4, 1, length($4)-2)}' to get offset
• Go into your kernel parameters and add resume=UUID=### resume_offset=###
• e.g. in /boot/refind_linux.conf (with efi partition unmounted)
• go into /etc/mkinitcpio.conf and add “resume” after the “filesystem” and before the “fsck” hooks
• run mkinitcpio -p linux-zen (or equivalent linux type)---

I do not know what sort of power management software exists by default on Ubuntu, but for laptop use I would strongly recommend getting a power management package like TLP to configure power profile settings for your laptop when on battery and on charge. It can greatly improve battery performance. Some alternatives like auto-cpufreq and powertop exist, but I have tried all 3 and found that TLP worked the best for me.
