I know have my qhyccd drivers installed and working. Thanks so much

I am having trouble installing specific hardware dkms because the dkms requires the linux header files for the installed kernel version which are not available or do not exist. Armbian 23.05.1 Ubuntu 22.04 desktop version is build with kernel 6.6.63 but an apt search for the relevant headers finds none. Headers exist for 6.2, 6.5 and 6.8 but not for 6.6. How can I address this?

After an update to Armbian 23.05.1 Ubuntu one of my Wifi adapters no longer sees any access point and can't be forced to connect blindly. The two adapters are very similar: The two adapters are very similar: Working Wifi Module 5B: |__ Port 2: Dev 9, If 2, Class=Vendor Specific Class, Driver=rtl8821cu, 480M ID 0bda:c820 Realtek Semiconductor Corp. /sys/bus/usb/devices/1-1.2 /dev/bus/usb/001/009 Not working Wifi Module 5A: |__ Port 4: Dev 10, If 0, Class=Vendor Specific Class, Driver=rtl88XXau, 480M ID 0bda:a811 Realtek Semiconductor Corp.

I would like to update/upgrade to the latest dist for the Armbian N2 without completely re-installing. Is this supported and possible?In order to update to the latest Armbian

The problem turns out to be the kernel version. The minimal image comes with 6.1.30 which provides a new video device (called None-1) and the desktop image comes with 6.1.11 which does not have this mystery video device. All working with the reverted kernel.

Seems the fix is to use kernel 6.1.11 that comes with the desktop version and not 6.1.30 that comes with the minimal version.

it turns out this mystery video device (None-1) is provided by Kernel 6.1.30 and revertiong back to 6.1.11removes the device.

So I edited the boot.cmd file and added this line after each of the setenv bootarg ... lines : setenv bootargs "${bootargs} video=None-1:d" recompiled with sudo mkimage -C none -A arm -T script -d /boot/boot.cmd /boot/boot.scr checked the lines had made it to boot.scr and rebooted. But the None-1 video device still persists and xrandr still shows that device is being used by Xorg!!!

I am unable to configure Xorg to ignore (and stop using as its default) the None-1 video device causing me not to be able to display a desktop via the HMDI-1-1 device. It has been suggested (https://ubuntu-mate.community/t/how-to-configure-xorg/26732/3) that I disable this device in the kernel, hopefully, via a kernel option such as : video=None-1:d Does anyone know where (which file) and how (specific method) I should do this?

Armbian 23.5 Ubuntu Not sure what I touched but my OpenGL has reverted from the Mali-G52 hardware accelerated renderer back to the llvmpipe. How can I changed this?

I have multiple n2s and I don't want them all to be called odroidn2. What is the recommended way to change the hostname of an armbian system?

I noticed this on the download page for the Odroid N2/N2+: On modern kernels adding “video=HDMI-A-1:1920x1080M@60D” to boot /boot/armbianEnv.txt (extraargs=) should force HDMI to 1080p instead of the 4K native resolution. I'll check if that will also works with 2560x1440 monitors!

@Dantes Thanks I took a look at your script. I don't think it will address my QHD resolution at boot issue! Good work, 👍

I managed to get it going! I suspected it was working so unplugged the HDMI cable from my QHD monitor and plugged it into a FHD and wala instant picture. Then I plugged it back into my QHD monitor and it was still displaying. I then used the display control to set the resolution to 2560x1440 and it still worked. So the problem seems to be using QHD from boot. That doesn't work. Seems like a firmware setting that should be changed. I suspect it doesn't see a FHD single so assumes a 4K monitor instead.

Thanks I went into armbian-config but can't see any setting that would be relevant as GUI is already set to enabled! I tried disabling and re-enabling but no difference. Blank screen!
