NAME

lsgpus - list graphics cards with details, outputs, and connected monitors

SYNOPSIS

lsgpus [OPTIONS]

DESCRIPTION

lsgpus lists all graphics cards (GPUs) with their driver, VRAM, PCI address, and for NVIDIA cards: utilization, memory usage, temperature, and power draw. Each GPU output port is listed with its connection status and, when connected, the monitor's manufacturer, model, and size (parsed from EDID).

GPU information is obtained from /sys/class/drm and lspci(8). NVIDIA runtime stats are obtained from nvidia-smi(1) when available. Monitor identification uses EDID data from /sys/class/drm/card*-*/edid.

lsgpus is similar in spirit to lscpu(1), lsusb(8), and lspci(8), but focused on graphics cards and their display outputs.

The binary is named lsgpus (with a trailing “s”) since v0.2.0, to avoid a name clash with the lsgpu(1) utility shipped by igt-gpu-tools — a low-level debug/test tool for the Intel Graphics Tests framework (different audience, same Unix path namespace).

OPTIONS

Output all GPU information as JSON.
Compact output with one line per GPU.
Show all output ports, including disconnected ones (hidden by default).
Continuously refresh the listing in place every SEC seconds (default 2), showing live NVIDIA stats. Press Ctrl+C to stop — there is no quit key.
Show version number and exit.
Show help message and exit.

OUTPUT

For each GPU: card name, full GPU model, driver, VRAM size, and NVIDIA runtime stats (utilization %, memory used/total, temperature, power draw). Below each GPU, output ports are listed with connection status and connected monitor details.

In --watch mode the same data is redrawn in place, with a utilization progress bar and a rolling sparkline per card — e.g. while a model loads on card1 via Ollama:
