Khadas Edge 2 hdmi 1140p and wacom tablet

[Egert]

Hi!

 

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?

1440p should be supported on both 6.1 and 6.10 images but it's recommended using 6.1 images as 6.10 HDMI is still WIP

I have identical monitors, but I am not sure about the correct armbian version. With this build I cannot get both screens to be at 1440p.

Which resolution are they working at? And does it work with Khadas images

[Egert]

It works with an Ubuntu 24.04  development test build from oowow.

 

My screens are 2560x1440

I will check it to find what's wrong. Unfortunately it might take some time since i don't have any 2k screen

What about wacom tablet support? I see libinput exists, but my tablet is not detected?

Here's my data point, fwiw, for the khadas edge 2 and a Wacom One 13" Touch display tablet with touch screen capabilities.

 

With the rolling distro and the 6.1.75/vendor kernel, everything works (stylus, usb c one-cable connection to the monitor using USBDP Alt Mode, etc) EXCEPT the touchscreen does not function.  Also, for whatever reason, in the Gnome Settings app under Wacom Tablet  there are FIVE entries, not one.  I attempted to compile a newer libinput, and this made no difference.  I think, for whatever reason, the wacom driver in the kernel (which is compiled in, not modular) is too old to recognize my hardware correctly.

 

With the edge kernel image of the rolling distro (variously 6.10-rcX, 6.10.Y, and now 6.11-rcZ), absolutely everything, including the touch screen, works fine, but the USBDP Alt Mode does not work on the board (yet), so I have to use the Wacom 3-in-1 cable.

 

I have a non-wacom cheapo portable monitor with a multi-touch screen, and it works on either distro just fine (although it's not got a stylus, of course).

 

No idea if this is useful to you or not. Both monitors I'm using are 1080p, not 1440p.

It is fixed now. It should work if you update kernel from beta repo

Yes it's not supported by mainline kernels yet.

Perhaps it might be worth to try to backport wacom drivers to 6.1 kernel.
