RPI 3B keeps going to blank screen (cursor showing)

BigTJ

I ran your script with the following result;-

disable screensaver via gsettings was true and uint32 300
disable screensaver via lightdm.conf
lxsession screen saver already disabled

Does this mean the screensaver is already off or that the script has disabled the screensaver?

Thanks again

BigTJ

@BigTJ script has disabled

@sdetweil

Thanks for your help.

This has been a problem for a long time. The mirror is being used headless so having to restart over and over again has spoilt the usefulness of the mirror. Hopefully that is all sorted.

Will let you know after testing.

Thanks again.

@sdetweil Unfortunately I am still getting the black screen with mouse cursor.

I’ve installed a new OS from scratch and Installed a clean version of MM, installed the modules from scratch but the problem persists.

When the MM has gone to black screen I cannot use CtrlM to minimise the MM window but I can use CtrlR to force a re-read and this brings the MM back on. Any ideas what can be causing this?

Thanks

I don’t know exactly when the black screen occurred.
Hope this helps

@BigTJ

I asked because I had problems with some modules which needed to much memory which results also in a black screen with white cursor.

You could try to run without the 3 foreign modules to see if the problem persists.

BigTJ

@karsten13

I have another MM running on a Pi 4B that uses all the same modules without a problem.

But I will give your suggestion a try. Thanks for the tip
