+# pacifidlog
+
+## Overview
+
+Lenovo Legion Go with AMD Z1 Extreme. Gaming beast. Uses Jovian for Steam Deck-like interface.
+
+## Todo
+
+- \[x\] update hdd-ui and adjustor.
+- \[ \] upgrade to large SSD.
+
+## Specs
+
+| Model   | Legion Go                 |
+|---------|---------------------------|
+| Display | 8.8" 1600x2560 144Hz      |
+| CPU     | AMD Z1 Extreme            |
+| RAM     | 16GB LPDDR5 (soldered)    |
+| GPU     | AMD Z1 Extreme            |
+| Disks   | 512GB M.2 2242 NVMe       |
+
+## Filesystems
+
+### /
+
+Encrypted LUKS btrfs volume.
+
+## Display
+
+Vertical-turned-horizontal 1600x2560 display running at 144Hz. Scales perfectly to 2x.
+
+## Steam / Jovian Docs
+
+Jovian delivers a Steam Deck-like interface on top of NixOS, with some limitations. This includes performance optimizations, patched versions of Mesa, and other tweaks to be as consistent with the Steam Deck as possible.
+
+### Features
+
+#### What works
+
+- Basic performance settings (frame limits, refresh rates, etc).
+- Desktop mode with KDE.
+- Installing GOG and EGS games with Heroic.
+- Launching and playing games, natively and with Proton.
+- Plugins and themes with Decky Loader.
+
+#### What does not work
+
+- Adaptive Brightness.
+- EmuDeck.
+- Formatting microSD cards.
+- Night light.
+- System updates.
+- TDP control and Legion Go specific features (all work with Handheld Daemon).
+
+### Decky Loader
+
+Decky loader can be installed and configured through the Jovian modules, but needs CEF Remote Debugging enabled via Deveroper Options for the frontend UI to load.
