Thank you very much for your help Kai-Heng Feng and please excuse me for answering that late. I tried out every kernel parameter you wrote but unfortunately it didn't work. I even shutdown twice when I changed the kernel parameter. I also ran "sudo update-grub" every time I edited /etc/default/grub. Luckily the kernel parameter "reboot=a" triggered a message I haven't had before: "A stop job is running for Make remote CUPS printers available locally". Could there be the problem? Is it possible that a BIOS setting is preventing my laptop from shutting down correctly? And if yes, what setting could it be?
When I first recognized that the my laptop isn't shutting down properly, I installed Windows to see if it worked with Windows and it did. But Windows didn't load the touchpad drivers correctly, so I couldn't use it. I've also made some changes this week: I installed Kali Linux on a second hard drive. After changing the kernel parameter some messages appeared during boot, but they went away to fast, so I couldn't read them good. All I could read is that it is connected with the hard drive on which Ubuntu is installed. I hope that helps you helping me :) On 04.02.20 15:36, Kai-Heng Feng wrote: > Please remove "acpi=force", and try the following kernel parameter > instead: "reboot=b", "reboot=a" "reboot=k", "reboot=t", "reboot=e" or > "reboot=p". > -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1860800 Title: Ubuntu 19.10 doesn't shutdown To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1860800/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
