Autostarts but doesn't run, will run on restart

ember1205

Would there be more value in coding in a check for to see if it’s Raspbian or possibly even bullseye and adding a two second sleep if there is?

raspberry_pi=$(grep ID /etc/os-release | cut -f2 -d=)
if [ "$raspberry_pi." == "raspbian" ] ; then
   sleep 2
fi
xorg=$(pgrep Xorg)

Maybe there’s a better string to search for, but it might be a stop-gap that would help?

@ember1205 i don’t think thats right… as we could have the same problem on any other system…

ember1205

@sdetweil

Correct syntax would need to be:

  raspberry_pi=$(grep ^ID= /etc/os-release | cut -f2 -d=)
  if [ "$raspberry_pi." == "raspbian" ] ; then
   sleep 2
  fi

The RPi 3B+ is a little slower to initialize on Bullseye versus Buster. Any time a device is running a slightly heavier OS and needs a little more time to finish booting up, I could see this occurring. The question is, do you solve it with a fix that impacts everyone (“sleep 2” or similar), test for particular OS/HW combo’s, or is there another process to look for that would better indicate when the system should be finished initializing?

Right now, it looks for X and just “moves on” when it isn’t found and assumes some sort of mistake or something in the config. Great as a fail-safe, but creates a new occasional issue to be dealt with.

@ember1205 that test is for when MM is running under docker (with no X running) but using the docker host’s xorg for viewing…

ember1205

@sdetweil

The test I’m referring to checks to see if X is running. If not, it moves on to test for Lubuntu. If that also fails, it assumes server only and moves on.

I do recall seeing a specific Docker test at the very beginning of the script, but that’s a fair bit earlier than where I’ve added this check (which is right before the “pgrep Xorg” line).

sdetweil

@ember1205 yes… i am looking for a test that works if the system is slow…

i added the rm of ./config folder and my pi 0 now comes up instead of the chrome desktop
which was random before…

        if [ $(which $b). != '.' ]; then
             rm -rf ~/.config/$b 2>/dev/null   # add this line

@sdetweil said in Autostarts but doesn't run, will run on restart:

… my pi 0 now comes up instead of the chrome desktop
which was random before…

Not sure I’m following what this should mean?

sdetweil

@ember1205 you had another problem where chrome comes up to the white screen w the icons. that is the chrome desktop.

i added the delete of the config folder to the run start script to get it back to just MagicMirror

ember1205

@sdetweil

Oh… now I follow.

sdetweil

@ember1205 can u try this on the reboot problem

add this

xprop -root      # add this line
xorg=$(pgrep Xorg)

then do the reboot test with the debugging still turned on
