Critical Error info-beamer pi

Hi,

I’ve been trying to run info-beamer pi on a Raspberry PI 4 (set to FKMS driver, GPU memory set to 256MB and installed all dependencies according to the readme file) unit but get the following errors:

Info Beamer PI 1.0.1.b40a5f~buster-fkms (https://info-beamer.com)
Copyright © 2012-2020, Florian Wesch fw@info-beamer.com

FKMS release for the Pi4. Be sure to read what has changed
compared to the classic info-beamer pi version on earlier
Pi models by running info-beamer -fkms.

info-beamer for the raspberry pi is free for private use. If you
would like to make use of this software in a commercial way, you
must buy a license which will support the continued development.

You might also take a look at info-beamer hosted. It’s the best
platform to run your info-beamer code. It does all the hard work
for you: installation, maintenance, asset delivery, management…
That way you can focus on the content. Learn more at:

Please advise how to solve this.
Thanks

Sorry about the massively delayed response. Notification for new topics got stuck somewhere.

This is most likely the reason. info-beamer works best with root permissions as it requires access to some resources (for example KMS or the Pi firmware) that’s not user-accessible by default.

One thing I noticed is your firmware version is from Sep 2020. It has been updated since then. {Pi release notes: rpi-eeprom/release-notes.md at master · raspberrypi/rpi-eeprom · GitHub} I would suggest updating the EEPROM and trying it again. [ Raspberry Pi 4 boot EEPROM - Raspberry Pi Documentation ]
Good luck.

While that’s generally a good idea, this isn’t the root cause seen in the log output. It’s definitely a permission issue.
