Hi again, I was able to narrow the problem down. I noticed that indeed a new kernel version has been installed today causing the problem. Output of dpkg.log:
cat /var/log/dpkg.log | grep "^2022-01-.*\ installed\ .*linux-image-generic" 2022-01-05 09:35:21 status installed linux-image-generic-hwe-20.04:amd64 5.11.0.44.48~20.04.22 2022-01-12 16:42:17 status installed linux-image-generic-hwe-20.04:amd64 5.11.0.46.51~20.04.23 2022-01-19 13:47:05 status installed linux-image-generic-hwe-20.04:amd64 5.13.0.27.29~20.04.13 When I boot with the previous kernel version 5.11.0.46, everything works fine. So the bug is apparently introduced in version 5.13. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1951717 Title: Ubuntu 21.10 not booting with 2 screens attached To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1951717/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
