Its hammering the processor on the Pi 3 pretty bad The chip is getting hot. I am going to add a heat sink and a fan to it before I do more. Thanks for your help.

@BlackTalon Interesting. Thanks for figuring out the issue.

Question: I could load this on the Raspberry Pi 3 at the office and then take a video of the end result. Would that be interesting to the community? Or should we just call this a greater-than-raspberry module?

@bhepler I am using on my win10 dev machine and unbuntu mini-itx 32" inch mirror so it runs great but yes I’d be interested in the RPI-3 info! :)

@Eunanibus : your module name has conflicted with this one MMM-Globe. I suggest you change your Globe module name.

Well, this sucks. I tried to enable the GL drivers on my Raspberry Pi 3 and it crashed the Pi. It installed the drivers, asked me to reboot and then the Pi won’t come back up. I’m going to have to reflash the card and start over.

It’s going to be a long night. If you’re going to try the GL drivers, back up your config.js at the very least. Better yet, image your SD card just in case.

I had the same black screen issue on my pi3. I reflashed my card twice before realizing I could have disabled opengl by editing the boot config.txt file. This might save someone else some time. So if you enable opengl and get the black screen issue remember to edit you config file to fix the issue.

dtoverlay=vc4-kms-v3ddtoverlay=vc4-fkms-v3d
gpu_mem=256
#dtoverlay=vc4-fkms-v3d

#Adding these two lines stopped the black screen issue.
hdmi_force_edid_3d=1
avoid_warnings=2

@d3r This.
I had the same issue on a Pi 2. Starting in safe mode (repeatedly mashing the Shift key on boot) got me up. Editing the boot config.txt file and commenting out the lines that get added when you enable the Open GL driver fixed things.

as anybody know why we have this issue ? I m reading that can be cause of the power supply ?

@BlackTalon got it running to on the rpi3, but it is flickering and sometimes blackscreen. Rpi3 is to weak i think.

@tidus5 The OpenGL drivers are experimental. I think we’re pushing the Pi - even the RPi3 - to its absolute limit with this type of rendering. A stable power supply isn’t the issue. It’s an issue of raw computing power.
