This is almost certainly bug 1958412, which was the first to report the static noise regression on the amdgpu driver after kernel 5.13 was introduced to Ubuntu 20.04.
Also ignore all comments that mention Nvidia because GNOME and Ubuntu only uses the primary GPU for shell rendering. Never the secondary GPU. Having just this bug separate when all the other reports of it are pointing to bug 1958412 probably won't help you. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1958591 Title: [amdgpu] Random noise 'static' display after internal display turned off/on To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-hwe-5.13/+bug/1958591/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
