Hardware Tooltip

An Omarchy bar widget that names the silicon in the machine, then stays out of the way.

Hover the chip for a Power-style panel: CPU model and per-core bars, RAM type and speed, GPU name and load, disk model and fill. It follows the active Omarchy theme. Click opens btop if you want the full TUI.

Hover Click
CPU name, per-core bars, RAM type/speed, GPU name, storage model and mounts Launch or focus btop

Load-aware status lines rotate the same way the Power panel does — idle machines loaf, busy GPUs push pixels, a local model run starts chewing context.

Why this exists

Omarchy Quattro's bar no longer ships a glance for what this computer is. Other listed plugins cover adjacent jobs:

  • btop Activity — a btop companion: launch, window mode, process sort, compact meters
  • System Stats / Vitals / Activity Monitor — full monitors with tabs, graphs, or process control

Hardware Tooltip is the other thing: a themed hover you can read in one look, with hardware identity on the labels, not just percentages. It is not a btop frontend.

ASRock BC-250

Tuned for the BC-250 / Cyan Skillfish board (1002:13fe). Linux binds the GPU as amdgpu, but SMU telemetry on this cut-down Oberon part is empty, so generic AMD tools report a stuck 0%:

Signal What Linux does on a BC-250
gpu_busy_percent node exists, read() returns ENOTSUPP
gpu_metrics average_gfx_activity stays 0xFFFF
radeontop unknown card, stuck 0%
DIMM / SPD none — 16 GB soldered GDDR6, dmidecode / inxi show type N/A and a 1750 MT/s command clock

This widget:

  • samples GPU load from /proc/*/fdinfo drm-engine-* time (Render/3D) instead of the broken busy node
  • labels memory as GDDR6 14000 MT/s from the published 14 Gbps-per-pin spec, not the command clock

Ordinary Radeons still use gpu_busy_percent. Intel uses DRM fdinfo / RC6. NVIDIA uses nvidia-smi only when the driver is actually loaded.

The 16 GB of unified memory is soldered GDDR6, not DIMMs, so dmidecode / inxi report type: N/A (the panel used to show a lone N) and a single 1750 MT/s command clock. There is no SPD to read. On PCI 1002:13fe / DMI BC-250 the widget uses the published 14 Gbps-per-pin spec as GDDR6 14000 MT/s.

Install

Plugins run as unsandboxed code inside omarchy-shell. Only add repos you trust.

omarchy plugin add https://github.com/IM0001GT/omarchy-hw-tooltip --enable

That clones into ~/.config/omarchy/plugins/im0001gt.hw-tooltip/, validates the manifest, and can drop the widget on the right side of the bar, next to Power.

Intel and AMD need no extra packages and no sysctl changes. On NVIDIA, if nvidia-smi is missing:

~/.config/omarchy/plugins/im0001gt.hw-tooltip/install.sh --deps

--deps is optional. Without it the widget still works; a missing NVIDIA tool just shows n/a for GPU.

One-shot from a clone

git clone https://github.com/IM0001GT/omarchy-hw-tooltip.git
cd omarchy-hw-tooltip
./install.sh

Use

  • Hover the chip — panel with CPU, memory, GPU, and storage
  • Click — launch or focus btop

The panel sizes itself to the hardware in the machine: more CPU threads add columns and height, extra disks grow the storage block, and the card still stops at the screen edge. On a 16-core / 32-thread desktop the thread grid uses four columns so Memory, GPU, and Storage stay on screen.

Move it with omarchy bar move im0001gt.hw-tooltip.

Update

omarchy plugin update im0001gt.hw-tooltip --yes
omarchy restart shell

omarchy plugin update only fast-forwards the git checkout. Quickshell can keep the previous QML in memory until the shell restarts. ./install.sh does the update and the restart together.

Uninstall

omarchy plugin remove im0001gt.hw-tooltip

Current releases do not leave a sysctl drop-in. If an older btop-monitor install set kernel.perf_event_paranoid=0:

~/.config/omarchy/plugins/im0001gt.hw-tooltip/install.sh --deps

or by hand:

sudo rm -f /etc/sysctl.d/99-omarchy-btop-monitor.conf /etc/sysctl.d/50-perf-event.conf
sudo sysctl -w kernel.perf_event_paranoid=2

Requirements

  • Omarchy with the shell plugin CLI (omarchy plugin add)
  • btop and jq (already on Omarchy)
  • Optional NVIDIA tools, only if nvidia-smi is missing
GPU Extra package How load is read
Intel none DRM fdinfo engine busy, then RC6 residency. No kernel.perf_event_paranoid change
NVIDIA nvidia-utils nvidia-smi, and only when the NVIDIA driver is loaded
AMD none gpu_busy_percent. If that node is missing or ENOTSUPP (BC-250), DRM fdinfo engine time

Hybrid laptops use the first source that actually returns a reading.

Layout

manifest.json          Omarchy plugin manifest (must live at repo root)
HardwareTooltip.qml    Bar icon + hover panel
preview.gif            README demo
preview.png            Marketplace still (teal theme)
docs/theme-night.png   Same panel after a theme change
scripts/system-usage   CPU / RAM / GPU / disk sampler
install.sh             Optional NVIDIA deps + enable / place the widget

The repo root is the plugin. That is what omarchy plugin add and omarchy plugin validate expect.
