First: I solved the reboot problem. I removed the kernel parameter "reboot=p" from /etc/default/grub.
Second: I found the following message in /var/log/syslog.1: "Feb 22 13:09:38 MSI kernel: [ 1.183278] ACPI: If an ACPI driver is available for this device, you should use it instead of the native driver". Could that be the problem? If that is the problem, how to get another ACPI driver? I attached the whole syslog.1 file, probably there is more useful information for you.

When I try, the shutdown screen appears. The first two dots below the ubuntu logo, turn orange and then it freezes. Reboot works fine. The debug-shell is no use, because at the freeze point I can't type in commands. When I press ESC to see what's going on during shutdown, the last message to appear ist "[Some weird number] reboot: power down. Last time I pressed ESC during shutdown the "weird number" was 85.270119. I also tried to shutdown with the terminal commands "sudo shutdown now", "sudo shutdown -P now", "sudo shutdown -h now", "poweroff" and "sudo poweroff -f". All of them had the effect as describe above except the command "sudo poweroff -f". After I typed in the command, I authenticated and following messages appeared: "Powering off...". At this point it freezed. I could still see the desktop and every visible window, but I couldn't perform any actions; not even keyboard shortcuts worked. It also did not help to change 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"' in /etc/default/grub to 'GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"' and run "update-grub". Once the following command combo did work: "sudo swapoff -a && systemctl poweroff", but the I reinstalled Ubuntu and now it doesn't work any more. In the application "Additional Drivers" I selected the proprietary and tested driver of NVIDIA, but I can't to this for my WLAN-Card (correct word?), because the "Additional Drivers" says it's not working, but my WLAN works fine. I've got only Bluetooth problems. The displayed name of the WLAN-Card is: "Intel Corporation: Wireless 7260 (Dual Band Wireless-AC 7260)". I also tried to manually install a driver it didn't help. When I wake up the laptop, a black screen appears with some error messages, but only for a very short time so I can't make a photo of it. I tried once and the text was unreadable. I have the latest BIOS and my Computer model is MSI PX60 2QD. It doesn't work with Arch Linux either.
