Hi Oliver, I have updated the project that this bug is opened against. Can you try to run the apport-collect again please? It should gather some useful information hopefully.
If that does not work please let me know. ** Package changed: linux-signed-hwe-6.8 (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2077405 Title: External screen flashing and cannot use after laptop lid closed Status in linux package in Ubuntu: Incomplete Bug description: With Kernel 6.8.0-40 (upgraded yesterday) a) the external screen connected to my Lenovo T14 ThinkPad randomly turns black for a few seconds and then recovers, b) the laptop cannot be used after the lid has been closed. The power LED is lit (no stand-by) but screen is blank. No reaction to any key, also cannot open a terminal with Ctrl-Alt-Fx. Only a hard reset is possible. None of these problems occur with Kernel 6.5.0-45. I have previously attempted to use Ubuntu 24.04 LTS but faced exactly the same issues, therefore I re-installed Ubuntu 22.04 LTS which was working stable until yesterdays kernel upgrade. While working with 24.04 LTS for a few weeks I also noted frequent, random and complete system freezes which made it unusable with that laptop. $ lsb_release -rd Description: Ubuntu 22.04.4 LTS Release: 22.04 ProblemType: Bug DistroRelease: Ubuntu 22.04 Package: linux-image-6.8.0-40-generic 6.8.0-40.40~22.04.3 ProcVersionSignature: Ubuntu 6.8.0-40.40~22.04.3-generic 6.8.12 Uname: Linux 6.8.0-40-generic x86_64 ApportVersion: 2.20.11-0ubuntu82.6 Architecture: amd64 CasperMD5CheckResult: pass CurrentDesktop: XFCE Date: Tue Aug 20 10:27:32 2024 InstallationDate: Installed on 2024-08-05 (14 days ago) InstallationMedia: Xubuntu 22.04.4 LTS "Jammy Jellyfish" - Release amd64 (20240216.1) SourcePackage: linux-signed-hwe-6.8 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2077405/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
