I started using Weston as a composer.
- Can I install a modeline from Weston?
- Maybe if you don’t have the opportunity to check, you can tell me which direction I need to look in order to add support for my screen?
Hello. I did some experiments
- I compiled the latest Ubuntu 24.04 with fenix
and run weston. Weston sees 1280x800 resolution

- I also noticed that the parameter HPOL - Positive is set in the edid of the screen. But hdmi_tx_mode.c vesa_modes is set to HPOL negative.
I tried changing it, but it didn’t give any effect
Please help me figure out what the problem is
Hello @Anton_Kalinichenko
Could you try to upgrade the kernel and check again?
It works for me with another 1280x800 screen, so we need you to check on your side.
Based on latest image (vim1s-ubuntu-24.04-xfce-linux-5.15-fenix-1.7.3-241129.img.xz) and follow the commands below to upgrade the kernel:
$ wget https://dl.khadas.com/.test/linux-image-amlogic-5.15_1.7.3_arm64.deb
$ sudo dpkg -i linux-image-amlogic-5.15_1.7.3_arm64.deb
$ sync
$ sudo reboot
Reboot to check again.
