June 1, 20242 yr Hello,  perhaps it's a noob question, but I am a noob, sorry 🙂  I had my BTT CB1 on Armbian 24.2.3 Bookworm CLI, with a BTT HDMI 5 display attached. Display was working fine. Flashed Armbian 24.5.1 Bookworm Minimal (no CLI available on the downloads page) and the display shows absolutely nothing. Flashed Armbian 24.2.3 back, and it works again.  What am I missing?  armbianmonitor -u file: https://paste.armbian.com/esoboqemot Â
June 1, 20242 yr Have the same experience on a Cubieboard2 ..the Xserver generates output on an Interface called "None-1" instead of HDMI-1-1. You can switch that with xrandr. but unfortunately xrandr needs an X11-Session with auth cookie to work. I've managed to login blindly and to fire up xrandr out of the .xsessionrc script but can't be called an solution. Please check your /var/log/Xorg.0.log if that is the case. As far as I know you can set the correct video output in the Xserver config file, /etc/X11/xorg.conf.. but you have to set up one first. Autogenerating one with Xorg --configure fails, so you have to do this by hand.   I've asked in the forum what would be the the intended way to switch the video output before the login bit got no answer at all.  Regards, Holm Â
June 1, 20242 yr Author Unfortunately it doesn't apply here. I have no Xserver installed. It's about the "text only" output right after / during boot. I'm not getting even that.
August 14, 20242 yr Could you try the new images? They are built with new enhancements for BTT CB1, and I have confirmed hdmi output with it. https://www.armbian.com/bigtreetech-cb1/
August 14, 20242 yr Author Thank you for your reply. For now I've put the CB1 aside, using a CM4, but another printer board is on it's way, and I will test it when it arrives. I will be back with a feedback in a couple of days. Â
September 22, 20242 yr The same problem. On Armbian_24.2.3_Bigtreetech-cb1_jammy_legacy_6.1.79.img the BT HDMI 5 application works, but Armbian_24.8.1_Bigtreetech-cb1_noble_current_6.6.44.img does not output an image at all. The display also does not work on Armbian_24.8.1_Bigtreetech-cb1_bookworm_current_6.6.44.img and Armbian_24.8.1_Bigtreetech-cb1_jammy_current_6.6.44.img. Â I'm sorry. The problem was not with the display. For some reason, Armbian did not load. Out of 5 different memory cards, I booted from only one. Edited September 22, 20242 yr by gensoloone
