Kernel

Touchscreen

Touchscreen is apparently some ELAN model. The driver is included in the vendor kernel at drivers/input/touchscreen/mediatek/ektf3249_VY36. It seems to work correctly with postmarketOS userspace.

Display

Without including msm-fb-refresher package, weston gui booted successfully and the desktop environment and postmarketOS demos menu were shows correctly. However, the screen was not updating at all, resulting in apparent nonresposiveness to touch and frozen datetime. Adding msm-fb-refresher solved the issue.
