Lindoze Process Manager

A Linux system monitor with the layout of Windows 11 Task Manager.

Most Linux system monitors (gnome-system-monitor, ksysguard, even the otherwise-excellent mission-center) collapse every CPU thread into a single overlaid graph. On a 32-thread machine that's unreadable. Lindoze gives you the per-thread grid you remember from Windows Task Manager, plus the rest of the Task Manager layout — sortable processes, performance pages, startup apps — in a single Qt app. Built and tested on KDE Plasma and GNOME (Fedora Workstation); should work on other Qt-capable desktops too.

See CHANGELOG.md for release history.

How this was built

I built Lindoze: the design, the layout, and every decision about how it works are mine, and I've personally reviewed and tested all of it across KDE, GNOME, and older hardware. I used an AI coding assistant (Claude Code) to help write it, and per Fedora's AI-assisted contribution policy I'm fully accountable for every line. It's GPL-3 and the complete source is right here to read and audit — you don't have to take my word for any of it.

Screenshots

The Performance tab defaults to the per-thread grid (right-click or toggle button to switch to the aggregate view):

Each cell shows its core's live clock speed and current load, so the grid reads at a glance instead of being 32 anonymous sparklines.

Disk and Network each draw both directions as one combined graph — two color-coded traces sharing an axis, with live values and a real scale label:

Processes tab — Grouped or Flat views, multi-select batch actions, search, and per-process controls (here in Flat view, sorted by CPU with three tasks selected):

Startup apps tab — toggle XDG autostart entries with a 10-second undo:

Features

• Performance tab with per-resource sub-navigation
  • CPU — aggregate + per-logical-processor grid (auto-sized; handles 2 to 128+ threads)
  • Memory — usage, swap, cached/buffers from /proc/meminfo
  • GPU — NVIDIA (via NVML), AMD (via sysfs), Intel (experimental — i915 perf PMU + hwmon); multi-GPU systems show one page per GPU
  • Disk — per-physical-device R/W throughput
  • Network — per-interface RX/TX throughput
• Processes tab — sortable tree, multiple view shapes
  • View menu — Grouped (collapsible User / System groups), Flat (one global list, so sorting by CPU surfaces the hottest process anywhere at the top), or User only / System only; your choice is remembered
  • Multi-select — Ctrl/Shift-click several processes and act on them at once: batch End / Kill / Suspend / Resume / Set priority, plus Copy PIDs / paths / command lines to the clipboard one per line. Processes you don't own are skipped.
  • Search across name, executable path, full command line, and PID
  • Selectable columns — show/hide the full executable path and command line (all arguments) from the Columns menu; your choice is remembered
  • Compact / Standard row density toggle — tightens row padding to fit more processes per screen (the font size stays legible)
  • Right-click actions: End task, Kill, Suspend/Resume, Set priority, Copy path / Copy PID / Copy command line, Open file location, Properties
• Startup apps tab — ~/.config/autostart/*.desktop entries; one-click toggle with 10-second undo and automatic .bak files
• View menu — Always on Top (works on X11; on Wayland the compositor controls stacking, so use its own "Keep Above"). A small minimum window size lets it tuck into a screen corner.

Requirements

• Python 3.10+
• A Qt 6-capable Linux desktop (KDE, GNOME, etc.)
• For GPU pages:
  • NVIDIA: the proprietary driver (provides NVML)
  • AMD: any modern amdgpu driver (kernel >=5.0); no extra packages needed
  • Intel (experimental): i915 driver, kernel >=5.13 for the perf PMU; reads engine utilization via perf_event_open and temp/freq via sysfs+hwmon. No subprocess, no root. The xe driver degrades to temp/freq only — Arc-on-xe testing pending. Older Gen7 (Ivy Bridge) hardware is known thin: freq reads work via fallback sysfs path but PMU util may return 0. If your Intel GPU is detected but util/temp/freq look wrong, please run lindoze --dump-gpu and file an issue with the output.

Install

Quick install with pipx (recommended)

If you have pipx installed, one command does it:

pipx install lindoze
lindoze

Update later with pipx upgrade lindoze; remove with pipx uninstall lindoze.

To track the development branch instead of the latest release, install from git: pipx install git+https://github.com/awn007-eng/lindoze.git.

(pipx itself: sudo apt install pipx on Ubuntu/Debian, sudo dnf install pipx on Fedora/Nobara, sudo pacman -S python-pipx on Arch.)

Fedora / Nobara (Copr)

On Fedora-family distros you can install Lindoze as a proper RPM — it pulls Qt6/PySide6 from the system repos and adds the Start-menu entry and icon for you:

sudo dnf copr enable awn007/lindoze
sudo dnf install lindoze

Built for Fedora 42/43/44 and rawhide. Update with sudo dnf upgrade lindoze; remove with sudo dnf remove lindoze.

From source (for hacking / customization)

git clone https://github.com/awn007-eng/lindoze.git
cd lindoze
./bootstrap.sh
./run.sh

bootstrap.sh creates a local .venv/, installs dependencies, drops a Start-menu entry into ~/.local/share/applications/, and installs the bundled icon. Safe to re-run — it's idempotent. Launch via ./run.sh or your desktop's Start menu.

Flatpak

Not yet shipping on Flathub — coming in a future release.

Limitations / not yet supported

• No per-process GPU/Network columns — these need root or eBPF on Linux. The totals are accurate; per-process attribution isn't.
• No Services tab — systemd unit management is well-covered by KDE's System Settings and systemctl; we're not duplicating it.
• No Users tab — single-user desktop assumption.
