Hi, I've build an SD card image with in a buildroot myself, used the stable branch as suggested. "For stable branch use --branch=v23.11"..and that all worked good so far. I'm no linux guy at all and begun some investigations, installed packages and configured the system, this was an desktop variant with xfce. Somewhere in the middle of work I've got the message that a security update is available and I should do an apt upgrade..done that. Interresting for me was, that I've got an Update to Armbian 24.2.1 jammy.. ok ..then this is so. I've noticed later that I don't have any video output from X11 anymore, after the login prompt the screen gets black with an cursor above left and later is shut off entirely, but the Xserver is still running, [pre] 1125 tty7 Ssl+ 0:06 /usr/lib/xorg/Xorg -core :0 -seat seat0 -auth /var/ru n/lightdm/root/:0 -nolisten tcp vt7 -novtswitch [/pre] xrandr output: [pre] xrandr Screen 0: minimum 8 x 8, current 3840 x 1200, maximum 16384 x 16384 DVI-I-0 disconnected primary (normal left inverted right x axis y axis) DVI-I-1 connected 1920x1200+0+0 (normal left inverted right x axis y axis) 518mm x 324mm 1920x1200 59.95*+ 1920x1080 60.00 59.93 1680x1050 59.95 1600x1200 60.00 1440x900 74.98 59.89 1280x1024 75.02 72.00 60.02 1024x768 75.03 70.07 60.00 800x600 75.00 72.19 60.32 640x480 75.00 72.81 65.99 59.94 DP-0 disconnected (normal left inverted right x axis y axis) DP-1 disconnected (normal left inverted right x axis y axis) DVI-D-0 connected 1920x1080+1920+0 (normal left inverted right x axis y axis) 521mm x 293mm 1920x1080 60.00*+ 50.00 1680x1050 59.95 1600x900 60.00 1440x900 59.89 1280x1024 75.02 60.02 1280x800 59.81 1280x720 60.00 50.00 1152x864 75.00 1024x768 75.03 70.07 60.00 800x600 75.00 72.19 60.32 56.25 720x576 50.00 720x480 59.94 640x480 75.00 72.81 59.94 DP-2 disconnected (normal left inverted right x axis y axis) DP-3 disconnected (normal left inverted right x axis y axis) [/pre] I've fiddeled around with some commands, but I'm unable to restore the Xserver Output on the DVI Output of the Cubieboard2. I have an DVI to VGA Connector plugged in and an TFT Display with the VGA Input to the converter. I'm unable to use the vga output that is provided at the DVK521 Board (WaveShare) too and already had planned to ask here how I can switch between the Video connectors with an actual Armbian. The last thing I've done where some entries in the armbianEnv to get an 2nd uart and the 1wire Interface enabled, that worked so far, but I was logged in with ssh from my host and haven't seen the X-Display from the Cubieboard2 since the monitor was switched to DVI which is connected to the host as 2nd monitor. I don't think that there is something wrong: [pre] armbianEnv: verbosity=1 bootlogo=false console=both disp_mode=1920x1080p60 rootdev=UUID=42951d58-2c17-42a5-af83-c6eaf7357967 rootfstype=ext4 overlay_prefix=sun7i-a20 overlays=uart3 w1-gpio param_uart2_rtscts=1 param_w1_pin=PB10 param_w1_pin_int_pullup=1 #extraargs=video=HDMI-A-1:1920x1080M@60 usbstoragequirks=0x2537:0x1066:u,0x2537:0x1068:u [/pre] The commented out extraargs line was from Igor suggested in another thread for a problem w/o connected monitor..but changed nothing. Can someone help me please? I hadn't much todo with Xserver setup in the last years..I'm tapping around pretty much in the dark.. Kind Regards, Holm

I get all working with USB Tethering, after install miniarch WiFi works...

I just bought 3 of these, 2 for me and one for a friend. I should have them by next week and can follow line by line instructions.

Oh thanks a lot! I could probably use the 1st patch to the armbianEnv.txt file: the root volume is on a usb drive, so the 2nd option would not work for me. But I still believe there is some hardware issue because even when USB ports work, the voltage supplied to is far below 5V. And the issue I have has been getting worse over the years, as if a component was wearing out. I'll report back when I can give it a try.

wifi operational with: ln -sf /lib/firmware/brcm/brcmfmac4330.bin /lib/firmware/brcm/brcmfmac4330-sdio.rockchip,rk3528-demo1-lp4-v10.bin ln -sf /lib/firmware/brcm/brcmfmac-ap6330-sdio.txt /lib/firmware/brcm/brcmfmac4330-sdio.rockchip,rk3528-demo1-lp4-v10.txt and a reboot, then nmtui to set up a connection
