dri3 extension not supported

[leftyleo]

@kayakbabe -
No problem - that was on topic
I actually tried going to 32 and i believe i am back to 64 but i will need to recheck
-i get the same error on both, even with sdetweil’s recommendation above to add the --disable-gpu switch

at least whatever was hanging up MM , it is working now
and i am banging my head against modules and minor CSS to add background

It can be frustrating but it is fun to search for possible solutions and experiment and learn

@leftyleo what module problems?

I am getting the same error on a fresh sd card on a rpi 3B with buster 32bit installed. It has manually installed MagicMirror, node, etc., no extra modules, just the config sample copied to be config.js.

I did more digging and I am not sure if this is the right solution for a Raspberry Pi 3B running Buster
I followed the instructions on this page [https://www.raspberryconnect.com/projects/35-games/142-trying-out-opengl-on-raspberry-pi-3] and the viz_main and gpu memory buffer and other stuff disappeared. I’m now playing with the different settings in the raspi-config and going to up the split memory. I tried first with settings it to 128 , half of what they recommended, cause I’m just contrary my mama says. And MagicMirror does seem to run more smoothly than with the default buster install. BUT the pi is much worse at multi tasking now. I can’t have very many chromium windows going at once. So, i’m going to play with the video setttings more. I know I won’t be running chromium when the mirror is running. But if I put a lot of modules into the magic mirror… it would stress the pi too.

Anyway, perhaps this info will help you.

Note: on the last buster install, the raspi-config advanced options and performance options are a little different location in the menu than described in this article.

@kayakbabe you can run raspi-config from the terminal window

@kayakbabe - been a bit out of sorts lately and havent had a chance to get back to MM after a new linux install. But finally all good there

–the MM still runs with the dri3 error for now. Perhaps it wont make any difference. Just one of those glitches. I thought it was why i could not boot. but it was (of course) an error i introduced in the config.js which i couldnt find and had to back track to the default and try again. Sure it is a little frustrating - but it is also how I learn ; by making mistakes.

–Now back to MM - I do not currently have a specific module issue. I want to have mostly basic stuff - like clock, Google calendar, weather - at least to start. I dont think i will need much else, i hope

I appreciate the help
Thanks everyone

Still strange that this dri3 not supported seems an enigma .
–i.ll keep an eye on it when MM starts up
Maybe it is a PI3B issue - i would think that is more likely and not a MM issue
–i am going back to the PRI forum to search and / or post the question there

ok havent worked on this in a couple weeks. well i have to re-image the card- the OS boot fails so badly that it goes to CLI prompt.
hardly had anything so starting from scratch again — but thats Not a MM issue --its a RPI issue
