I'm the owner of a Khadas Edge2, and I'm trying to run it with a USB-C DisplayPort (plus touch, plus Power) screen. That combination has historically failed for me, especially with newer kernel versions. There's an old thread in the Khadas user forum https://forum.khadas.com/t/usb-c-dp-stopped-working-after-apt-update/21788 describing the problem, but it went stale and unfixed.

I'm not a kernel developer, so I can't fix something like that myself. However, I recently ran an investigation with an agent that, although lengthy, appears to have produced a good fix. It's all in here, the documentation and the result: https://codeberg.org/graphicore/Edge2-USB-C-DP

It's based on Armbian. I'd like to see the issue fixed upstream, but since I'm not a kernel developer and I'm neither qualified nor familiar with the norms in that process, I'd like to find someone to take it from here.

If there's anything I can do to help and/or support please let me know.

Cheers, Lasse

Why does the system restart trigger at 3:30 every day？？

I used 'uptime'to check the changes in running time！

How to turn off the trigger！

How do I import it for compilation and installation?

I installed this image on my Khadas Edge 2

Armbian 24.5.5 Noble Gnome
MESA / VPU

I am wondering if it is possible to use Wacom tablet. I have seen Ubuntu builds from Khadas support it.

Another question is about 1440p monitor using hdmi port on Edge 2, newer Ubuntu development builds seem to have this option, what about Amrbian?

1. Enabled Panfrost in defconfig.

2. Add kisak-mesa ppa, apt update and upgrade.

3. Replace mali_csffw.bin by Armbian mali firmware.

After these, the gnome-settings shows the GPU is software vendoring. Hope to get your help~

Thanks!

May I ask where the system is configured in the framework to display prompt word identifiers after login？？？？

I made the following changes to /usr/share/initramfs-tools/hooks/osk-sdl:
 

24c24,28
<             ln -s "$(basename "${so_src}")" "${DESTDIR}/${so}"
---
> 	    if [ -f "${DESTDIR}/${so}" ] ; then
> 	      echo "FIXME: ${DESTDIR}/${so} exists! Skipping!"
> 	    else 
>               ln -s "$(basename "${so_src}")" "${DESTDIR}/${so}"
> 	    fi
71c75,76
<     exit 1
---
>     echo "FIXME: not exiting..."
> #     exit 1

Obviously, this isn't a long-term solution, I just wanted to make sure my system was bootable, and this allowed me to get that.

I should maybe add that it looks like the rolling release build of this didn't result in an OS image on the website -- I don't know if that is related or not:
 

• Missing: https://dl.armbian.com/nightly/khadas-edge2/Noble_edge_gnome
• Present: https://dl.armbian.com/nightly/khadas-edge2/Noble_vendor_gnome-kisak

The path '${kernelw_ork-dir}' actually exists, but why does it appear 'Cannon stat: No such file or directory' during compilation???

What are the configurations?

For the convenience of personal development, I forced the use of my kernel source code git address.

Please support me, thank you！！！

To enable HW acceleration, install the mesa package with the forced overwrite option or an archive to enable acceleration for wayland. To enable wayland acceleration, you need to replace the files in the /usr/lib/aarch64-linux-gnu directory with the contents of the archive (with file replacement). After that, acceleration will work with wayland. X11 and wayland acceleration works the same way on Debian Sid (the images are the same as Ubuntu). After starting the system and initial configuration, replace the files from the archive in the same way and acceleration will work. The results of running in Debian Sid Gnome for x11 and wayland.

dpkg -i --force-overwrite mesa_23.0.0-dev-2_arm64.deb 

After installation and reboot, HW acceleration will work in x11 and wayland.

Please note, this is a test version of mesa for the initial evaluation of the work, some of the functions do not work in it and there may be bugs.

With x11, the system works more stably, but the test results are lower than in gnome+wayland.
