If I don't add dtoverlay=vc4-fkms-v3d in the config.txt, the rpi4 board will have the same corrupted screen as the #1 for armhf kernel + armhf uboot.
On the rpi3 B+ board, if booting with the same uboot without dtoverlay=vc4-fkms-v3d + 4.15/5.0 raspi2 kernel, the hdmi display doesn't have this issue, it proves that the eoan kernel for raspi2 introduces a new issue, will find the root cause for this new issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1847596 Title: rpi3b+: corrupted screen on hdmi To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1847596/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
