--- title: Install DispCtrl on Debian using the Snap Store | Snapcraft description: Get the latest version of DispCtrl for on Debian - Per-display brightness, dimming, night light and snap layouts url: https://snapcraft.io/install/dispctrl-linux/debian --- [Canonical Snapcraft](https://snapcraft.io/) # Install DispCtrl on **Debian** # DispCtrl (dispctrl-linux) [akileswar](https://snapcraft.io/publisher/akileswar "View all snaps from akileswar") * [akileswar](https://snapcraft.io/publisher/akileswar "View all snaps from akileswar") * [Utilities](https://snapcraft.io/search?categories=utilities) [Install](https://snapcraft.io/install/dispctrl-linux/debian#install) #### Per-display brightness, dimming, night light and snap layouts # DispCtrl for Linux DispCtrl for Linux brings Windows 11–style display controls and window management to X11 desktops. Features include: * **Display temperature and dimming** — warm or dim displays using their gamma ramps. * **Night-light scheduling** — automatically apply display settings on a schedule. * **Display arrangement** — manage multi-monitor layouts. * **Laptop backlight control** — adjust the built-in display's backlight. * **Snap layouts and Snap Assist** — bring Windows 11–style window snapping to X11 desktops. A lightweight background engine starts at login and keeps your settings applied. Both the graphical interface and the `dispctrl-linux` command-line tool communicate with this engine. ## Requirements and Limitations ### X11 Required DispCtrl requires an **X11 session**. Wayland compositors control gamma ramps and window placement, so these features cannot be managed directly by DispCtrl under Wayland. ### External Monitor Brightness The Snap package cannot control an external monitor's hardware brightness through DDC/CI because strict Snap confinement prevents access to the required I²C buses. For external-monitor DDC/CI support, use the **`.deb` package or the release tarball** instead. ### Laptop Backlight Permissions Laptop backlight control requires an additional permission that the Snap package does not connect automatically. Grant it with: ```bash sudo snap connect dispctrl-linux:login-session-control ``` ## Credits DispCtrl for Linux is a Linux port of [DispCtrl](), originally created by [Jesvi Jonathan](). ## Documentation For Linux-specific installation instructions, configuration details, and troubleshooting, see the [Linux documentation](). ### Package name * dispctrl-linux --- ### License * MIT --- ### Last updated * 16 October 2026 - latest/stable * 19 October 2026 - latest/edge --- ### Websites * [www.akileswar.com](https://www.akileswar.com "https://www.akileswar.com") * [haythmkenway.github.io](https://haythmkenway.github.io/DispCtrl-linux/apt "https://haythmkenway.github.io/DispCtrl-linux/apt") * [github.com/HaythmKenway/DispCtrl-linux/blob/master/docs/LINUX.md](https://github.com/HaythmKenway/DispCtrl-linux/blob/master/docs/LINUX.md "https://github.com/HaythmKenway/DispCtrl-linux/blob/master/docs/LINUX.md") * [github.com/jesvijonathan/DispCtrl](https://github.com/jesvijonathan/DispCtrl "https://github.com/jesvijonathan/DispCtrl") --- ### Contact * [github.com/HaythmKenway/DispCtrl-linux/issues](https://github.com/HaythmKenway/DispCtrl-linux/issues "https://github.com/HaythmKenway/DispCtrl-linux/issues") * [hello@akileswar.com](mailto:hello@akileswar.com "mailto:hello@akileswar.com") --- ### Donations * [paypal.me](https://paypal.me/0x4kil "https://paypal.me/0x4kil") * [github.com/HaythmKenway/DispCtrl-linux#support-the-project](https://github.com/HaythmKenway/DispCtrl-linux#support-the-project "https://github.com/HaythmKenway/DispCtrl-linux#support-the-project") --- ### Source code * [github.com/HaythmKenway/DispCtrl-linux](https://github.com/HaythmKenway/DispCtrl-linux "https://github.com/HaythmKenway/DispCtrl-linux") --- ### Report a bug * [github.com/HaythmKenway/DispCtrl-linux/issues](https://github.com/HaythmKenway/DispCtrl-linux/issues "https://github.com/HaythmKenway/DispCtrl-linux/issues") --- ##### Report a Snap Store violation * [Report this Snap](https://snapcraft.io/install/dispctrl-linux/debian#report-snap-modal) --- [See more information about dispctrl-linux ›](https://snapcraft.io/dispctrl-linux) ## Enable snaps on Debian and install DispCtrl Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build.
