** Description changed: I am running Ubuntu 24.04.3 LTS on the laptop Lenovo Legion 5 15IAH7, and connected to an external monitor via HDMI. Since upgrading to the 6.8.0-71 kernel, it stopped recognizing the monitor. 6.8.0-64 works fine. 6.8.0-78 doesn't work. Possibly related Ask Ubuntu question, even though rolling back to the older Linux version didn't fix their problem: https://askubuntu.com/questions/1553967/ ProblemType: Bug DistroRelease: Ubuntu 24.04 Package: linux-image-6.8.0-64-generic 6.8.0-64.67 ProcVersionSignature: Ubuntu 6.8.0-64.67-generic 6.8.12 Uname: Linux 6.8.0-64-generic x86_64 NonfreeKernelModules: nvidia_modeset nvidia ApportVersion: 2.28.1-0ubuntu3.8 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: ori 3942 F.... wireplumber /dev/snd/controlC0: ori 3942 F.... wireplumber /dev/snd/seq: ori 3938 F.... pipewire CRDA: N/A CasperMD5CheckResult: pass CurrentDesktop: GNOME-Flashback:GNOME Date: Sun Aug 24 12:04:55 2025 InstallationDate: Installed on 2022-06-07 (1174 days ago) InstallationMedia: Ubuntu 22.04 LTS "Jammy Jellyfish" - Release amd64 (20220419) MachineType: LENOVO 82RC ProcFB: 0 i915drmfb ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-6.8.0-64-generic root=UUID=9c10dc40-0b10-40a8-ae9a-232f55df57dd ro quiet splash vt.handoff=7 PulseList: Error: command ['pacmd', 'list'] failed with exit code 1: No PulseAudio daemon running, or not running as session daemon.
