I only just noticed this is the same machine as bug 2136103 so the underlying issues are probably the same.
Try switching to the newer HWE kernel: sudo apt install linux-generic-hwe-24.04 and reboot. If the problems continue after that then it becomes more likely a cable/connector issue. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2136133 Title: [i915] External screen black after sleep To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2136133/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
