<![CDATA[Black screen with cursor issue.]]>Hey everyone.

I’ve been having an issue with my 3A+ connected to a pixel square 4x4 gpio touch display.

Everything config wise on bullseye 32 bit and mm are up to date. Modules are working with no errors. No weird orientation settings. The pixel square works great when mm is stopped. I just get a black screen with cursor. I’ve done a few from scratch installs and the issue continues. I can see the mm session through the 8080 web address and it looks good.

Modules are solaredge, mycommute, today’s weather, and tesla.

Any guidance would be greatly appreciated.

I do have this happen on another larger mm I have with a raspi4 2gb, it’ll goto black screen sometimes with cursor sometimes without, powercycle typically brings it right back.

I do have a pfsense fw with pfblocker. Could this create conflict?

Thanks.

I would like to sort this self hosted mm instance. It runs perfect in the web browser. Just blank screen with cursor. Is it possible a module can prevent everything from launching if it is too large and overlaps others?

then I just launch chromium over the mm server

Made change. No dice on my original MM device 4x4 pixelsquare. Black screen plus cursor. Startup out looks clean.

So one of my installs is mm.sh and the other is run-start.sh.

The mm.sh one only shows this error in start.

[2883:1218/201556.298300:ERROR:object_proxy.cc(590)] Failed to call method: org.freedesktop.portal.Settings.Read: object_path= /org/freedesktop/portal/desktop: org.freedesktop.DBus.Error.ServiceUnknown: The name org.freedesktop.portal.Desktop was not provided by any .service files

I think this has been covered and is insignificant, correct?

The run-start.sh one I’m going to reinstall.

Not sure how I ended up with 2 different installs, pretty I used your script.

So heres a question for ease of troubleshooting.

What if I do a couple dedicated proxmox lxc for servers and run the raspi displays as clients? I haven’t tried this method yet.

add

export ELECTRON_DISABLE_GPU=1

before the npm start line

with my install script, that is

~/MagicMirror/installers/mm.sh

Hopefully this is enough to narrow it down.

~/.pm2/logs

folder

notice the dot (.) I’m front of pm2

in Linux there is no hidden attribute so by convention anything with a leading dot I not shown by normal file list commands

System browser launches no problem.

Disabled the blocker rues for pfblocker on my iot vlan so its a straight shot to internet.

Whats the best way to dump logs? I am on pm2. Your auto install script.

Thanks

the blocker might cause a module error .any do not have error recovery…
