Public bug reported: Issue: Laptop internal display random noise, external monitor works. Rolling back to 5.11.0-46-generic works
Both kernels below causes he same issue 5.13.0-27-generic 5.13.0-28-generic First i thought it was due to installing CUDA. But removing CUDA and NVIDIA drivers didn't work. Only switching kernels did. I used the "ubuntu-bug linux" command to report this so i assume all necessary files are included automatically ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: linux-image-5.11.0-46-generic 5.11.0-46.51~20.04.1 ProcVersionSignature: Ubuntu 5.11.0-46.51~20.04.1-generic 5.11.22 Uname: Linux 5.11.0-46-generic x86_64 ApportVersion: 2.20.11-0ubuntu27.21 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: ubuntu:GNOME Date: Fri Feb 4 11:38:31 2022 InstallationDate: Installed on 2021-07-22 (196 days ago) InstallationMedia: Ubuntu 20.04.2.0 LTS "Focal Fossa" - Release amd64 (20210209.1) SourcePackage: linux-signed-hwe-5.11 UpgradeStatus: No upgrade log present (probably fresh install) ** Affects: linux-signed-hwe-5.13 (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug focal ** Package changed: linux-signed-hwe-5.11 (Ubuntu) => linux-signed- hwe-5.13 (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1960011 Title: Laptop internal display random noise, external monitor works.
