Linux vm

Or just something like Termux, a terminal emulator for Android. Example screenshot (XFCE desktop over VNC server), I didn’t know what to fit in there:

Full desktop apps, running natively under Android. For better compatibility Termux also has proot-distro (similar to chroot) where you can have… let me copy-paste

Supported distributions (format: name < alias >):

  * Alpine Linux < alpine >
  * Arch Linux < archlinux >
  * Artix Linux < artix >
  * Chimera Linux < chimera >
  * Debian (bookworm) < debian >
  * deepin < deepin >
  * Fedora < fedora >
  * Manjaro < manjaro >
  * openKylin < openkylin >
  * OpenSUSE < opensuse >
  * Pardus < pardus >
  * Ubuntu (24.04) < ubuntu >
  * Void Linux < void >

Install selected one with: proot-distro install <alias>

Though there is apparently some performance hit. I just prefer Android, but maybe you could run even full LibreOffice under some distro this way.

If it can be done by Termux, then someone like Samsung could definitely make something like that too, but integrated with the system and with more software available in their repos.

What’s missing from the picture but is interesting too is NGINX server (reverse proxy, lazy file sharing, wget mirrored static website serving), kiwix-serve (serving ZIM files including the entire Wikipedia from SD card) and Navidrome (music server).
And brought to any internet-connected computer via Cloudflare QuickTunnel (because it doesn’t need account nor domain name). The mobile data upload speed will finally matter, a lot.

You get the idea, GNU+Linux. And Android already has the Linux kernel part.
