Hello everyone, I have 4 VIM3 devices that I am using for a special project. I am using touchscreens with these VIM3s, but for the screens to work, I need to manually set the HDMI resolution in the /boot/env.txt file because it doesn’t recognize the screen in Auto Detect mode. I can do this HDMI setting in the env.txt file for kernel 4.9. However, in a new Ubuntu version, for example, 22 which uses kernel 5.15, there is a Uenv.txt file instead of env.txt. But from the documentation, I don’t know how to specify the HDMI resolution in this file. Additionally, I need to disable I2S to use some pins as GPIO, which I am also unable to do. If you can help with this or suggest a resource, I would be very grateful.
We don’t maintain the image with 4.9 kernel anymore, we suggest you to use the image with 5.15 kernel.
What’s the resolution of your screen? Could you provide the edid to us? You can follow the command below:
edid-decode < /sys/class/drm/card0-HDMI-A-1/edid
I2S is disabled by default in 5.15 kernel image, you don’t need to disable it manually.
My resolution is "1024×600 Progressive 60Hz hdmi=1024x600p60hz "
thanks for answer
Hello @Mithrandir
Can you check this image with your 1024x600 screen ?
Thank you @numbqq , I will try this image and give you feedback.
Hello again @numbqq , first of all, I tried the command ‘edid-decode < /sys/class/drm/card0-HDMI-A-1/edid’ you gave for the kernel 4.9, you can see it in the image below:
Then, I flashed the Khadas with the image you suggested (https://dl.khadas.com/.test/vim3-ubuntu-22.04-gnome-linux-5.15-fenix-1.6.9.1-240806-emmc-develop-test-only.img.xz) and tried the
‘edid-decode < /sys/class/drm/card0-HDMI-A-1/edid’ command you gave, and I got the following output:
When I connect a different model touch screen, I get a result:
However, when I connect the 10.1" touch screen that I need to use for the project, I don’t get any display on Ubuntu 22 with kernel 5.9 or higher. I only get a display with kernel 4.9. As I mentioned before, I can achieve this by adding the arguments hdmi_auto_detect: no and hdmi=1024x600p60hz in the /boot/env.txt file.
Hello @ivan.li ,
I am using the screen from this link ‘HDW101-A5001L 10.1inch Touch Screen Display | Roboway’ with a Khadas VIM3. On Kernel 4.9 with an Ubuntu 20.04 image, I can get a display on this screen when I add the arguments ‘hdmi_auto_detect: No’ and ‘hdmi=1024x600p60hz’ in the /boot/env.txt file. However, on a higher kernel version (like 5.15) and Ubuntu 22.04, I cannot get any display on this screen. I have another touch screen (different model), and everything works correctly when I use it. When I entered the console commands provided by @numbqq, I got the results mentioned above. Unfortunately, I cannot get any display on the DWIN 10.1-inch screen (Ubuntu 22.04 and kernel 5.15) in any way. I need to work on Ubuntu 22.04 for my project. I need help with this issue.
Hello @Mithrandir
Judging from the phenomenon you described, there is a problem with your connection, or there is no power supply, or the screen is damaged.
I will try it with another screen that I am sure works and let you know the results.
You can also try the command below:
edid-decode < /sys/class/amhdmitx/amhdmitx0/rawedid
Please check on the 5.15 kernel image above.
I tried the screen on khadas vim1s and Fenix 1.6.9 Ubuntu 22.04.4 LTS Linux 5.15.119.

By the way, I want to mention something important. The display works on Ubuntu 22 and later. I don’t understand how this is happening, but the display works on Ubuntu 22 and 24. However, on Ubuntu 20, I have to manually set the resolution.
Could you tell us which image you mean work?
About Ubuntu 22.04 & 24.04 what’s the kernel version ? Provide the below information to us:
$ cat /etc/fenix-release
$ uname -a
If it works what issues you have? Support 1024x600 resolution? For current image we support aonther 1024x600 resolution screen, but for yours have a different timing, so we need to adaptor it.
About Ubuntu 20.04 what’s the kernel version ? Provide the below information to us:
$ cat /etc/fenix-release
$ uname -a
