I think the original 1013 had flicker and tearing before the screen went blank (the os was still functional - ssh worked).
With your image/modules/buildinfo i get: uname -a Linux ubuntu 5.3.0-1013-raspi2 #15+v3d SMP Sun Nov 24 13:41:44 CST 2019 aarch64 aarch64 aarch64 GNU/Linux Enlarging the glxgears window: I see flicker between the glxgears window, the background and terminal window when they overlap instead of just seeing the top one. It hasn't gone blank ... yet With pi 4.19 kernel/modules (from https://github.com/raspberrypi/linux) there is no flicker and the screen has never gone blank. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-raspi2 in Ubuntu. https://bugs.launchpad.net/bugs/1850876 Title: CONFIG_DRＭ_V3D is disabled for linux-raspi2 of eoan Status in linux-raspi2 package in Ubuntu: Confirmed Status in linux-raspi2 source package in Eoan: Fix Released Bug description: We enabled DRM_VC4 in the linux-raspi2 of eoan, but disabled the DRM_V3D. 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.
