Installing `libegl1` makes weston run, but GPU is not used, rendering is done via software mesa.

Hi, I'm trying to run weston on Odroid XU4, but it does not start. Seems something is wrong with GPU drivers. I have installed "Armbian 25.2.1 Bookworm Minimal" image and then installed weston via apt. Then, trying to run the weston fails with error: Date: 2025-04-13 UTC [13:47:44.248] weston 10.0.1 https://wayland.freedesktop.org Bug reports to: https://gitlab.freedesktop.org/wayland/weston/issues/ Build: 10.0.1 [13:47:44.249] Command line: weston [13:47:44.249] OS: Linux, 6.6.81-current-odroidxu4, #1 SMP PREEMPT Mon Dec 30 15:59:39 UTC 2024, armv7l [13:47:44.249] Flight recorder: enabled [13:47:44.249] Starting with no config file.

Runing weston in pixman mode with "weston --use-pixman" succeeds, but I need accelerated weston. Any idea how I can install the missing GPU drivers?

The following has resolved the issue for me: armbian-upgrade sudo apt remove libraspberrypi0 libraspberrypi-bin sudo apt update sudo apt upgrade thanks to geoW here: https://help.nextcloud.com/t/internal-server-error-after-php8-3-upgrade-on-12-apr-ncp-1-55-3-on-rpi5/222576/2

@JamesCL Thanks, English is not my native language, so it's very easy for me to make a mistake. I assume it 🙃 On the other hand, @Daniel Nuñez Villegas, if you tell me how can I test I2C I can check my OPi. But from tomorrow I'll be out for a few days, so it will take some time... Regards.

As a rule, you also need to set the processor frequency to the maximum value and make it unchanged and configure the Linux kernel scheduler.
