Hi, both dmesg logs you attached are of 5.3.0-18-generic, not 5.3.0-40-generic. Could you try to locate your last boot of 5.3.0-40-generic by:
$ journalctl -k -b <num> where <num> is -1 for last boot, -2 for the second last boot and so on. Save full output with: $ journalctl -k -b <num> | tee dmesg.5.3.0-40-generic And, could you also try to boot 5.3.0-40-generic without "quiet splash" but with "3", which will send you into console mode if successful. No need to append other debug parameters. It seems kernel has successfully booted and we may need to diagnose GUI environment rather than linux kernel. So let's try booting into no GUI mode. If that works, you should try: 1. booting with 5.3.0-40-generic normally (with "quiet splash" removed) again, 2. wait for a few minutes after screen turns blank, 3. force power off 4. use `journalctl -b -1` to dump *all* syslog messages and attach them here. -- 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/1866879 Title: Failure to boot on linux-image-5.3.0-40-generic Status in linux package in Ubuntu: Confirmed Bug description: I installed Ubuntu on the laptop, rebooted and everything was fine. I did an upgrade to all packages and found that when I rebooted, it fails to load. I found out that a workaround is to select linux- image-5.3.0-18-generic in grub which leads me to think that the issue is related to the upgrade of the linux-image 5.3.0 package. To be clear, linux-image-5.3.0-18-generic works but linux- image-5.3.0-40-generic does not.
