*** This bug is a duplicate of bug 1958412 *** https://bugs.launchpad.net/bugs/1958412
The duplication of this to https://bugs.launchpad.net/bugs/1958412 is not appropriate I think. * I do not have the symptoms described in the other bug * The workaround described there (remove `quiet` from grub command line) does not help, unsuprisingly. Also the `[amdcpu]` addition to the title seems inappropriate since people seem to have the same issue on NVidia. To be clear: the other issue is random display noise during boot and shutdown. I do not see that. The other bug does not mention this bug's symptom, which is an unusable display if it's ever turned off and then on again (e.g. by suspend/resume, or external monitor plug/unplug). ** Summary changed: - [amdgpu] Random noise 'static' on internal display when turned off/on + [amdgpu] Random noise 'static' display when internal display turned off/on -- 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 when 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 ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
