dotfiles-sheng

Personal NixOS and Home Manager configuration for Xiaomi Pad 6S Pro 12.4 (sheng).

This repository imports the published nixos-sheng hardware platform from GitHub. You do not need to clone nixos-sheng next to this repository.

Features

• Multi-Desktop Environment Support: Easily switch between GNOME, KDE Plasma, Phosh, and Hyprland without reinstalling the system.
• Touch & Mobile Optimizations: Hardware sensors enabled for auto-rotation, native Wayland virtual keyboards configured for Plasma (maliit) and Hyprland (wvkbd).
• Memory Optimized: ZRAM is enabled globally with a 50% threshold to maximize tablet multitasking performance. GNOME background bloat is stripped out by default.

Available Desktop Profiles

You can seamlessly switch your entire desktop environment by deploying different NixOS configurations defined in this repository:

1. GNOME (Default) - sheng The default upstream experience with tablet gestures. Command: nh os switch ~/dotfiles-sheng -H sheng

2. KDE Plasma 6 - sheng-plasma Highly optimized memory usage with excellent Wayland touchscreen support. (Recommended) Command: nh os switch ~/dotfiles-sheng -H sheng-plasma

3. Phosh - sheng-phosh Purism's minimalist touch-first desktop environment based on GNOME technologies. Command: nh os switch ~/dotfiles-sheng -H sheng-phosh

4. Hyprland - sheng-hyprland Extremely lightweight Wayland compositor for advanced power users. Command: nh os switch ~/dotfiles-sheng -H sheng-hyprland

Performance & Storage Metrics

Here is the NixOS closure size footprint for each desktop environment configuration (compiled natively for aarch64-linux):

Desktop Environment	Profile Name	System Closure Size	Status	Notes
GNOME	sheng	7.3 GiB	✅ Success	The default upstream experience. Heavy but feature-complete.
Hyprland	sheng-hyprland	6.7 GiB	✅ Success	The lightest compositor available, saving over 600MB compared to GNOME.
KDE Plasma 6	sheng-plasma	-	⚠️ Failed	Linking qtwebengine may cause Out-Of-Memory (OOM) on 8GB devices. Binary cache is recommended.
Phosh	sheng-phosh	7.6 GiB	✅ Success	Minimal touch interface, optimized for mobile devices.

First deploy

Clone this repository on the tablet, then deploy from inside the repository:

git clone https://github.com/DotRedstone/dotfiles-sheng.git
cd dotfiles-sheng
nix flake update
sudo nixos-rebuild switch --flake .#sheng-plasma

If Nix reports Truncated tar archive while fetching firmware, pull the latest dotfiles and run nix flake update again. This repository overrides the firmware input to use git+https instead of GitHub tarball downloads.

After this system configuration is activated, you can use the aliases:

• nrs to rebuild the base system
• hms to apply Home Manager configurations

Enjoy your multi-desktop optimized tablet experience!
