Blank screen after a couple of hours

[bradley1982]

@sdetweil HI sam,

it auto lauches when the pi reset.

it seems to work for a couple of hours/day and then i get the blank screen with the cursor. I can see it on the remote control app and look ok but the screen is blank.

When i reset the pi it works ok for the same period… and the blank screen?

is there a log that i can run to figure out what is causing it?
again really new to all this and need an idiot guide lol

[sdetweil]

@bradley1982 i assume you use pm2 to autostart.
if so, then

pm2 logs --lines=xxxx
where xxxx is a number of lines to display from the latest part of the logs.
xxxx defaults to 15

there are only 500 places where one needs a guide. lol.

[bradley1982]

@sdetweil lol!

cool i have ran that, presume that i check this later and see if i get an error message form one of the modules?

sorry for the stupid questions

[sdetweil]

@bradley1982 yes, you can empty the current (old) collection of log messages by

pm2 flush

[bradley1982]

@sdetweil got this initially when i ran it … (pm2 log)

no idea what this means? can still see it working ok on remote control but the screen is blank?

many thanks in advance

[sdetweil]

@bradley1982 can you do it another way

pm2 stop all
cd ~/MagicMirror
npm start >somfile.txt 2>&1

when the black screen happens, ctrl-c on the command window with the npm start in it

ctrl-q might work on the MM black screen but maybe not

[bradley1982]

@sdetweil Hi Sam

Nothing seems to happen when i do the control c however when i do the control q on the blank screen on the MM it bring me back to the config file and the terminal window.

bradley@raspberrypi:~ $ pm2 stop all
cd ~/MagicMirror
npm start >somfile.txt 2>&1
