Linux: how to turn on/off native Wayland mode

Question

Does IntelliJ IDE support Linux Wayland mode natively?

Answer

For IDE versions until 2025.3.X:

IntelliJ IDE runs in XWayland mode (as a native x11 app, and Wayland runs it in compatibility mode). To turn on native Wayland support (beta): add -Dawt.toolkit.name=WLToolkit to "Help | Edit custom VM options" and restart the IDE. To turn off native Wayland support (beta): remove -Dawt.toolkit.name=WLToolkit from "Help | Edit custom VM options" and restart the IDE.

For IDE versions 2026.X and newer:

IntelliJ IDE runs in native Wayland mode in a Wayland session by default. To turn off native Wayland support: add -Dawt.toolkit.name=XToolkit to "Help | Edit custom VM options" and restart the IDE.
