Hi, I am having a problem getting the graphical login to work... What I run is an ubuntu jammy image with gnome, however when I boot with my tv connected via hdmi it seems to work at first but finally I end up with a screen just displaying the above error. armbianEnv.txt contains the line "disp_mode=1920x1080p60" (a mode my TV supports), yet when the device starts it uses the 4k mode - could this be part of the problem? So how could I get this working and how would I ensure that my device only uses fhd resolution, even though my tv can also do 4k? Many thanks!

So what I want is to control 433Mhz power plugs from my orange pi. I have both a sender and a receiver module that get connected via the gpio pins. For the plugs I have a remote control and now i need a way to replicate that behaviour - ie I need a program that can sniff the 433Mhz signal coming from the remote control and analyze it in such a form that I can send it out again via the sender. In the good old sysfs times there were tools (like the 433Utils I mentioned above) that could do that - and my question is how this is done today...

Hi, what are currently the options of controlling 433Mhz sender/receiver devices from an orange Pi zero 3? Currently the gpios are no longer exposed via sysfs but you could re-enable that feature by compiling a new kernel with the proper configuration. Then wiringpi would work again and you could use 433Utils. But what would be the options without compiling a new kernel? What 433Mhz library exists that uses the new way of controlling the gpios? I am a bit confused about the current state of affairs, please enlighten me...

Hi, I am having problems connecting my orange pi zero 3 to my TV via hdmi: No matter what I try the TV reports "no signal". Before I came to armbian I have tried the vendor-supplied debian and arch images and could not get hdmi output on any of them, so it might be that my micro-hdmi adapter is faulty or that the hdmi-port on the device itself is faulty, but over the weekend I cannot replace any hardware so I thought I try here to see if anyone has an idea on what to try. The image I am currently running is Armbian_community_24.5.0-trunk.58_Orangepizero3_jammy_current_6.6.17_gnome_desktop.img. When I log into the device I can see that an Xorg process is running. xrandr produces this output: Screen 0: minimum 320 x 200, current 1024 x 768, maximum 8192 x 8192 HDMI-1 connected primary 1024x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm 1024x768 60.00* 800x600 60.32 56.25 848x480 60.00 640x480 59.94 When I disconnect the hdmi-cable xrandr reports "HDMI-1 disconnected", so at least a little bit of hdmi-functionality is there... The device is connected via an micro-hdmi adapter and a hdmi-cable, I have checked the hdmi-cable but I do not have another adapter nor do I have another micro-hdmi device, so unfortunately I cannot test the adapter. What I have noticed is that (at least sometimes) the device seems to lose network-connectivity (ethernet) when the hdmi-cable is connected - and regains connectivity as soon as the hdmi-cable is disconnected, so there seems to be some conflict between hdmi and ethernet. I do not know where the display modes come from that xrandr displays as the TV is a 4k model that supports a lot more modes. So my question is: Is there anything I could try to get hdmi working or at least to narrow down the problem?
