Some games are using old SDL version that is compiled without Wayland support. That means they will not likely want to run - crash on startup - if SDL_VIDEODRIVER is set to Wayland.
You can switch between wayland and x11 in the file ~/dotfiles/hypr/conf/custom.conf:
sh
# SDL version
env = SDL_VIDEODRIVER,wayland
# env = SDL_VIDEODRIVER,x11NOTE
In versions before 2.9.5RL you find the entry in ~/dotfiles/hypr/conf/ml4w.conf
Toolkit Backend Environment Variables
These environment variables help ensure proper backend support in Hyprland:
| Variable | Value |
|---|---|
GDK_BACKEND | wayland,x11,* |
SDL_VIDEODRIVER | wayland |
CLUTTER_BACKEND | wayland |
TIP
Move the following line to your custom.conf file for better control:
ini
env = SDL_VIDEODRIVER,wayland
