If you consider a house server, the standard suspects will come to thoughts. The Raspberry Pis, small NUC-style PCs, previous laptops, have all lengthy been fantastic gadgets to run a house server on. However when you these have them mendacity round, your telephone may simply match the invoice.
You see, operating a full Linux desktop in your Android is not some technical wizardry anymore. It is a matter of putting in a few apps and operating just a few instructions. And when you get to that Linux desktop, the road between a Linux PC and your telephone will skinny out actual fast.

Why would you run a house server on an previous, probably below powered Android machine you may need mendacity round when options just like the Raspberry Pi are for wherever between $30 to $100 on Amazon? That is a good query to ask. However the reply can also be fairly easy: since you already personal it.
In case you’ve acquired an previous laptop computer or desktop mendacity round otherwise you wish to study extra about embedded programs through the use of a Raspberry Pi, by all means, go for it. They’re finally a greater answer contemplating they’re really meant to run desktop Linux. Nevertheless, in case you do not already personal them, they often require shelling out cash after which ready on transport to reach. To not point out that within the case of the Raspberry Pi, you may additionally want a show, keyboard, mouse, microSD card, and an influence provide to get all of it operating. Instantly, you would be taking a look at a large invoice.
Your telephone, then again, already has all of it. It is probably acquired rather more than 8 GB of area, a show, contact enter, and a built-in battery. You are not changing Android in your telephone both, and might at all times revert to common Android if you have to use your telephone as, properly, a telephone.
And when you’re questioning whether or not you may really run something helpful on it, there are tons of issues you are able to do with a Linux terminal on Android that common apps cannot. Something from operating a Pi-hole occasion for network-level advert blocking, a Copyparty occasion for a file server, or perhaps a Navidrome music server on an previous Android is well doable. In case you’ve acquired the {hardware}, you may even self-host your individual AFFiNE server and break free from Notion.

You need not unlock the bootloader, root your telephone or do something flashy to put in Linux. Android 16 now natively helps a Linux terminal, however if you’d like the complete desktop expertise, a mix of Termux and Termux X11 will take you a great distance.
There are tons of set up scripts out there on GitHub that automate the setup course of for you, so as a substitute of putting in particular person instruments, the distribution, and the XFCE desktop, you simply run an set up script to put in every thing mechanically. I used the Cellular HackLab script from jarvesusaram99 on GitHub. It installs every thing you want, plus a bunch of additional utilities like Firefox, Wget, cURL, VS Code, and even Wine to get you began. It additionally has a relatively pleasant terminal interface that tells you precisely what is going on on.

Earlier than you go round tweaking Android settings nevertheless, you may must run yet another Termux command as quickly as you begin your session:
termux-wake-lock
You can even add it to your ~./bash_profile so it runs mechanically on boot. This command prevents Android from placing your telephone into deep sleep and throttling the Linux processes when its display screen turns off.
Subsequent, take away each app you do not want, and prohibit background exercise for those you may’t uninstall or in any other case want on the telephone. Simply head to Settings > Apps > Battery utilization and set each app to Restricted. Keep in mind: each background course of that you simply take away offers extra {hardware} headroom on your Linux atmosphere. Underneath Developer Choices, you too can set the Background course of restrict to a hard and fast quantity — a setting that may make your previous Android telephone quicker.
Final however not least, disable battery optimization for each Termux and Termux X11. The apps ought to mechanically immediate you to do that, so you do not even must dig by means of your telephone’s settings. Android’s battery administration may be fairly harsh on apps taking over an excessive amount of energy, and letting Termux run free ensures your Linux atmosphere runs steady.
