MykrosCursor

Overview

MykrosCursor is an OS-level cursor replacement (not an overlay) for Linux and Steam Deck. Swap out obscure or hard-to-see cursors—even in games that include their own cursors—with the theme you choose. This functionality was previously almost exclusive to Windows; MykrosCursor bridges the gap, working seamlessly in both Desktop and Gaming Mode.

Multi-monitor support - Multi-monitor support with no FPS impact.

User-space only – no kernel drivers; compatible with common anti-cheat services.

Anti-cheat compatibility

MykrosCursor operates strictly at the desktop/input layer on Linux and Steam Deck. It replaces the cursor with your chosen pointer whenever a game asks the system to display one—without touching game memory, altering gameplay logic, or requiring elevated (root) privileges.

We’ve tested MykrosCursor with the various anti-cheat systems and encountered no issues. Policies can change, so please review your game’s Terms of Service before use.

Ease of use

MykrosCursor is designed to be simple to set up and effortless to maintain.

Just launch the app once to complete the initial configuration—after that, all you need to do is restart your system or Steam Deck. Once rebooted, the cursor theme settings and cursor hook activate everywhere automatically.

In most cases, no manual desktop configuration is required. If your Linux desktop environment doesn’t automatically switch to the MykrosCursor theme, you may need to open your system’s appearance settings and select it once. This only applies to the first setup, with the configuration remaining persistent across reboots. This step is only needed to switch over to MykrosCursor—once selected, you can change cursors inside MykrosCursor without needing to do this again.

If a game ships with its own custom cursor and you want to override it, the process is just as easy. Simply enable Compatibility Mode on the game:
Steam Library → right-click the game → Properties → Compatibility → check "Force the use of a specific Steam Play compatibility tool."

Once enabled, MykrosCursor will correctly replace the game's built-in cursor. This only needs to be done once per game—after that, you can freely switch between any cursor or theme inside MykrosCursor without touching the compatibility setting again. This is only needed for games that ship with their own cursors, for games that use your standard cursor it will be replaced automatically.

Any time you change cursors, colors, or configurations within MykrosCursor, simply close and re-open the app to see the new cursor take effect. While the Steam UI itself may not visually update until Steam is restarted, your games will immediately use the updated cursor once that specific game is restarted—no full Steam restart required.
