We have [previously mentioned](../Getting-Started/Quick-start/#wrapping-the-launcher-recommended) using a wrapper to launch Hyprland. Whether you
|
|
start Hyprland through TTY or a Display Manager, it is recommended to use a wrapper.
|
|
As such, you can pass certain environmental variables to improve Wayland compatibility, or
|
|
simply change certain aspects of your desktop.
|
|
|
|
Please avoid putting those environmental variables in /etc/environment. That will cause all
|
|
sessions (including Xorg ones) to pick up your wayland-specific environmental on traditional
|
|
Linux distros.
|
|
|
|
## XDG Specifications
|
|
|
|
- `XDG_CURRENT_DESKTOP=Hyprland`
|
|
- `XDG_SESSION_TYPE=wayland`
|
|
- `XDG_SESSION_DESKTOP=Hyprland`
|
|
|
|
XDG specific environmental variables are often detected through portals and applications that may
|
|
set those for you, however it is a good idea to provide them in your wrapper script as a fail-safe.
|
|
|
|
## QT Variables
|
|
|
|
- `QT_AUTO_SCREEN_SCALE_FACTOR=1` - [(From the QT documentation)](https://doc.qt.io/qt-5/highdpi.html)
|
|
enables automatic scaling, based on the monitor's pixel density
|
|
- `QT_QPA_PLATFORM="wayland;xcb"` - Tell QT applications to use the Wayland backend, and fall back to x11 if Wayland is unavailable
|
|
- `QT_WAYLAND_DISABLE_WINDOWDECORATION=1` - Disables window decorations on QT applications
|
|
- `QT_QPA_PLATFORMTHEME=qt5ct` - Tells QT based applications to pick your theme from qt5ct, use with Kvantum.
|
|
|
|
## NVIDIA Specific
|
|
|
|
To force GBM as a backend, set the following environment variables:
|
|
|
|
- `GBM_BACKEND=nvidia-drm`
|
|
- `__GLX_VENDOR_LIBRARY_NAME=nvidia`
|
|
|
|
> See [Archwiki Wayland Page](https://wiki.archlinux.org/title/Wayland#Requirements) for more details on those variables.
|
|
|
|
- `LIBVA_DRIVER_NAME=nvidia` - Hardware acceleration on NVIDIA GPUs
|
|
|
|
> See [Archwiki Hardware Acecleration Page](https://wiki.archlinux.org/title/Hardware_video_acceleration)
|
|
> for details and necessary values before setting this variable.
|
|
|
|
- `__GLX_GSYNC_ALLOWED` - Controls if G-Sync capable monitors should use Variable Refresh Rate (VRR)
|
|
|
|
> See [Nvidia Documentation](https://download.nvidia.com/XFree86/Linux-32bit-ARM/375.26/README/openglenvvariables.html) for details.
|
|
|
|
- `__GL_VRR_ALLOWED` - Controls if Adaptive Sync should be used. Recommended to set as "0" to avoid having problems on some games.
|
|
|
|
- `WLR_DRM_NO_ATOMIC=1` - use legacy DRM interface instead of atomic mode setting. Might fix flickering issues.
|
|
|
|
## Toolkit Backend Variables
|
|
|
|
- `SDL_VIDEODRIVER=wayland` - Run SDL2 applications on Wayland. Remove or set to x11 if games that provide older versions of SDL cause
|
|
compatibility issues
|
|
- `_JAVA_AWT_WM_NONEREPARENTING=1` - Fix possibly broken Java applications. Set to 1 until Wakefield is available.
|
|
- `CLUTTER_BACKEND="wayland"` - Clutter package already has wayland enabled, this variable will force Clutter applications
|
|
to try and use the Wayland backend
|
|
|
|
- `GDK_BACKEND` - Force backend for wayland-enabled GTK3 and GTK4 backends. Available options are "wayland" or "x11". If GTK XWayland
|
|
applications cause issues when set to "wayland", try "wayland,x11"
|
|
|
|
## Theming Related Variables
|
|
|
|
- `GTK_THEME` - Set a GTK theme manually, for those who want to avoid appearance tools lxappearance or nwg-look
|
|
- `XCURSOR_THEME` - Set your cursor theme. The theme needs to be installed and readable by your user.
|
|
- `XCURSOR_SIZE` - Set cursor size. See [here](../FAQ/) for why you might want this variable set.
