I have added the above-mentioned part to the kernel command line (file /etc/default/grub), done "sudo update-grub", and rebooted.

I have run sudo dmesg > dmesg-boot-log-20241031.txt to obtain a boot log and attach the output. ** Attachment added: "dmesg-boot-log-20241031.txt" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2084046/+attachment/5833459/+files/dmesg-boot-log-20241031.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2084046 Title: [i915] Phantom "Unknown" display detected on Intel Meteor Lake To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2084046/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
