V2.31.0 unable to start

[sdetweil]

@htilburgs could be

when you open a terminal session and do

env

is the WAYLAND_DISPLAY variable set?

that code you referenced says use WAYLAND_DISPLAY, and if not set, set it to wayland-1

[htilburgs]

@sdetweil It seems it’s not set

How do I set this?

[sdetweil]

@htilburgs in terminal window no spaces between things…
this is like the windows set var=value (without the set prefix)

WAYLAND_DISPLAY=wayland-x

x is a number from 0 to …

we thought wayand-1 was default

[htilburgs]

@sdetweil said in V2.31.0 unable to start:

WAYLAND_DISPLAY=wayland-x

In terminal window I typed WAYLAND_DISPLAY=wayland-1
Then I did “env”, nothing changed.
npm run start:wayland still gives the same error.

[sdetweil]

@htilburgs said in V2.31.0 unable to start:

Then I did “env”, nothing changed.

you should have seen this in the env output

but our code says IF NOT SET, use wayland-1
which looks like an error

so if you set it to the same value it won’t improve

I’d try wayland-0

maybe the wlr_randr command will tell you what it is?

[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

[sdetweil]

@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

[sdetweil]

@rkorell xrandr needs DISPLAY

[rkorell]

@sdetweil yes :-)

[sdetweil]

@rkorell oops, never can remember when i need to use underscore vs dash! thanks for the catch!
