V2.31.0 unable to start

htilburgs

@sdetweil Maybe I don’t understand.
WAYLAND_DISPLAY=wayland-0 still gives wayland-1 in npm run start:wayland.

wlr_randr gives

pi@MagicMirror:~/MagicMirror $ wlr_randr
-bash: wlr_randr: command not found

By the way, my PIR command do work

onCommand: "WAYLAND_DISPLAY='wayland-1' wlr-randr --output HDMI-A-1 --on --transform 270 --mode='1920x1080'",

offCommand: "WAYLAND_DISPLAY='wayland-1' wlr-randr --output HDMI-A-1 --off",

htilburgs

When I give command

pi@MagicMirror:~ $ WAYLAND_DISPLAY='wayland-1' wlr-randr --output HDMI-A-1 
HDMI-A-1 "Samsung Electric Company SyncMaster 0x00000001 (HDMI-A-1)"

@htilburgs so wayland-1 seems to be correct

rkorell

@htilburgs said in V2.31.0 unable to start:

-bash: wlr_randr: command not found

shouldn’t it be wlr-randr ?

Regards,
Ralf

htilburgs

@rkorell
You’re correct, but then I get

rkorell

@htilburgs :-)
this is correct on console window.
console didn’t know about display unless you’re telling him what display to use.
As far as I know you can use

DISPLAY=:0.0

as a hint upfront your terminal command.
At least for xrandr this works and is necessary.

DISPLAY=:0.0 xrandr --output HDMI-1 --off

is my xrandr console equivalent for the “normal” command

xrandr --output HDMI-1 --off

I’m not THAT sure if this is true for wlr-randr .
(Because wlr-randr do have this environment variable “WAYLAND_DISPLAY” which is not the case for xrandr…)

HTH & regards,
Ralf

@rkorell xrandr needs DISPLAY

rkorell

@sdetweil yes :-)
