This script will enable all HDMI videos, passing xrandr OPTIONS to each one of
|
|
them.
|
|
|
|
To do this automatically when the cable is plugged, add the following
|
|
udev rule (Linux only):
|
|
|
|
$ cat /etc/udev/rules.d/hdmi.rules
|
|
SUBSYSTEM=="drm", ACTION=="change", RUN+="/bin/sh $0"
|
|
EOF

|
XRANDR_BUF=$(xrandr)
|
|
PRIMARY=$(echo "$XRANDR_BUF" | awk '$1 !~ "HDMI" && $2 == "connected" {print $1; exit}')
|
|
HDMI_OUTPUTS=$(echo "$XRANDR_BUF" | awk '$1 ~ "HDMI" && $2 == "connected" {printf $1 " "}')
|
|
set -- $HDMI_OUTPUTS
