@hein-jan Thanks for sending your reply! I saw that in the set-up instructions as well, but for some reason, I couldn’t get xrandr to rotate the display. I was curious if we needed the GL Driver at all, but based on recent comments in this thread, it seems that others don’t. I commented the Driver out and things seem to be working fine now. Thanks again!

@hrjmsh did you do anything special to get xrandr to rotate your display for your vertical setup? I disabled fmks and reverted to full kms (dtoverlay=vc4-kms-v3d), but couldn’t get the screen to rotate.

If you have any insight or advice, it’s greatly appreciated :)

@hein-jan I had the same problem as well, switching from fkms to kms. When I switched to kms, the flickering went away, but I was unable to rotate 90 degrees for my vertical display.

Have you come across any solutions? Or has anybody else? Thanks in advance for your insight!

@sean Thank you so much, Sean!

Hi Folks,

Can someone please help troubleshoot the error in my config file? I’m not a professional dev, and could use some assistance :) Please reference below:

var config = {
	address: "localhost", // Address to listen on, can be:
	                      // - "localhost", "127.0.0.1", "::1" to listen on loopback interface
	                      // - another specific IPv4/6 to listen on a specific interface
	                      // - "", "0.0.0.0", "::" to listen on any interface
	                      // Default, when address config is left out, is "localhost"
	port: 8080,
	ipWhitelist: ["127.0.0.1", "::ffff:127.0.0.1", "::1"], // Set [] to allow all IP addresses
	                                                       // or add a specific IPv4 of 192.168.1.5 :
	                                                       // ["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.1.5"],
	                                                       // or IPv4 range of 192.168.3.0 --> 192.168.3.15 use CIDR format :
	                                                       // ["127.0.0.1", "::ffff:127.0.0.1", "::1", "::ffff:192.168.3.0/28"],
