Minimal :

Monitors

Weston's outputs differ slightly from those of Monitors:

is the unused built-in video adapter. The add-on adapter  is cabled to one HDMI and one DVI monitor, so the output names are HDMI-A-1 and DVI-I-1.

XWayland

See Wayland#XWayland for details and an overview of available packages.

Set the following to activate the use of XWayland:

Note: if X is not already configured you may need to configure a keymap: Keyboard configuration in Xorg

High DPI displays

For Retina or HiDPI displays, use:

Shell font

Weston uses the default sans-serif font for window title bars, clocks, etc. See Font configuration#Set default or fallback fonts for instructions on how to change this font.

Tips and tricks

Screencast recording

Weston has built-in screencast recording which can be started and stopped by pressing the + key combination. Screencasts are saved to the file in the current working directory of Weston. The WCAP format is a lossless video format specific to Weston, which only records the difference in frames. To be able to play the recorded screencast, the WCAP file will need to be converted to a format which a media player can understand. First, convert the capture to the YUV pixel format:

$ wcap-decode --yuv4mpeg2 capture.wcap > capture.y4m

The YUV file can then be transcoded to other formats using FFmpeg or (see for more).

Window switching

To switch windows with instead of Super+Tab change to KEY_SPACE in and recompile weston.

EGLstream support (for proprietary Nvidia Driver)

See Wayland#Requirements for reference.

You can find weston-eglstream packages on AUR, that contain special patches.

gollark: * after

gollark: Er, then it would fail to work correctly, yes.

gollark: Er... no, potatOS autoupdate will overwrite the startup.

gollark: You can't without my keys or another computer.

gollark: Okay, that'd work.
