Monitors
Weston's outputs differ slightly from those of xorg.conf Monitors:
$ ls /sys/class/drm
card0
card0-VGA-1
card1
card1-DVI-I-1
card1-HDMI-A-1
card1-VGA-2
card0 is the unused built-in video adapter. The add-on adapter card1 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:
~/.config/weston.ini
[core]
xwayland=true
High DPI displays
For Retina or HiDPI displays, use:
~/.config/weston.ini
[output]
name=...
scale=2
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 Super+r key combination. Screencasts are saved to the file capture.wcap 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 x264 (see x264 -h for more).
Window switching
To switch windows with Super+Space instead of Super+Tab change KEY_TAB to KEY_SPACE in desktop-shell/shell.c and recompile weston.
