short version: With raspberry pi 4: your binaries applied (https://people.canonical.com/~hwang4/v3d-fix/) The screen flickers then blanks I installed an built the latest mesa The screen flickers then blanks Back to the raspberry pi kernel (4.19) Which still works...

In fact the DRM_V3D is crucial for graphical applications (such as ubuntu-desktop :) as it removes the graphical overhead from the cpu to the gpu, making the applications work much faster. Please refer to https://bugs.launchpad.net/ubuntu/+source/linux- raspi2/+bug/1848703/comments/32 [Impact] Users reported that we should enable the DRM_V3D, then the GPU will be fully used when running "ubuntu-desktop" [Fix] Enable the DRM_V3D, the v3d.ko will be built [Test Case] Users already tested it, it worked well. https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1848703/comments/36 [Regression Risk] Low, I already did building test for arm64 and armhf, all passed. And uers already tested the kernel module, it worked as expected.
