Here is a cleaned up description and example of the workaround for the combination of Raspberry Pi 5 Ubuntu Core Ubuntu-Frame
Workaround Description: The correct overlay to use is `vc4-kms-v3d-pi5` but you will likely need to `sudo snap refresh` to get it. However, after you have the correct overlay, I can confirm that the path to the overlay `vc4-kms-v3d-pi5` will be too long when loaded and will silently fail. To work around this first you need to shorten the path to the correct overlay used on Raspberry Pi 5 by coping and renaming it. Next you will need edit your `/run/mnt/ubuntu-seed/config.txt` to use the correct overlay with shortened path name. After a reboot Ubuntu Frame will be working and the display will show the correct URL provided. My workaround: (only for Raspberry Pi 5) Starting with a fresh install of Ubuntu Core on the Raspberry Pi 5 ``` sudo snap refresh sudo cp /boot/piboot/pi-kernel_1047.snap/overlays/vc4-kms-v3d-pi5.dtbo /boot/piboot/pi-kernel_1047.snap/overlays/vc4-pi5.dtbo sudo sed -i 's/dtoverlay=vc4-fkms-v3d,cma-128/dtoverlay=vc4-pi5/' /run/mnt/ubuntu-seed/config.txt sudo snap install ubuntu-frame wpe-webkit-mir-kiosk sudo snap set wpe-webkit-mir-kiosk url=https://ubuntu.com/core sudo reboot ``` -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2128161 Title: pi-kernel VC4-KMS not working with CM5 To manage notifications about this bug go to: https://bugs.launchpad.net/canonical-kernel-snaps/+bug/2128161/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
