NOSON fails to launch on new Raspberry pi 4

snap
1

Hello. Noob here so please be gentle. I recently built a fresh “buster” installation on a new Raspberry Pi 4. All defaults, nothing special. I followed the simple doc to install snapd then SONOS on the pi but when I launch NOSON (Desktop>Run>noson) I see a window pop then immediately close with no errors in syslog or daemon log. There are two log entries that say it “started” and “succeeded” but nothing else. Nothing displays in a ps, either. The NOSON snap appears to have installed properly and does mount. Any thoughts on where to start here?

try running it from a terminal window and see if it spits out any errors when run interactively from there

EDIT: there also seems to be an error tracker where you could report the issue at https://github.com/janbar/noson-app/issues

Errors below. Repeated lines were clipped. First try was as user “pi”. Second was w/sudo. Same thing - a window opens and closes in less than a second then abort. Please advise if there is a better way to display this info. Thanks.

I also opened issue #168 on janbar/noson-app github. Thanks. https://github.com/janbar/noson-app/issues/168

you can ignore the libarmmem lines, they come from a rather awful LD_PRELOAD hack RaspiOS applies system wide, while noisy they are harmless and have no impact.

This is your error, looks like something is wrong with the graphics driver or the mesa libs …

The app author responded on Github and suggested there was something wrong with snapd and to compile the app from source. After doing so now I get a white screen with a black horizontal bar across the middle of the screen when I launch the app and the pi hangs up. Still waiting for a reply to this on Github.
