Blank screen after a couple of hours

[sdetweil]

@bradley1982 that means another instance of mm is already running

[bradley1982]

@sdetweil Hi Sam,

how do i fix this?

[sdetweil]

@bradley1982 how does magicmirror get started? pm2 at boot?

if so , pm2 can do lots of things, from a terminal window do

pm2 status
pm2 stop all

and then

pm2 --help
for a list of all the options available

@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

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

@bradley1982 those are garbage error messages from electron. which we cant suppress. ignore them
