Ubuntu – After switching to Ubuntu 15.04 laptop won’t shutdown


I have a problem with with my laptop, Toshiba Qosmio F60. Curently i am running dual boot with Win7, and Ubuntu 15.04. I used different distros and this is the first time i have this kind of problem.

After i click shutdown Ubuntu logo shows with those dots, first one changes color then the screen shuts down. NumLock and power light are still on, cpu fan goes to full speed, and it stays that way. Only way to shut it down completely is by force.

Restart works fine.

I run 64-bit version of stock ubuntu 15.04, with generic 4.0.4-040004 kernel version

EDIT: Since i haven't found solution to this problem, i reinstaled Linux Mint 17.1. Now the same problem is happening. Before Ubuntu i was running Manjaro, Mint, Fedora and Kali. Everything was working fine. I was thinking that my laptop could be a problem, but from Windows and live versions it shuts down fine.

Having the same problem after upgrading to from 14.10 to 15.04 on my Dell Insperion 7537. Reboot works fine, shutdown acts like reboot.

this looks like it might be related Reboot after shutdown (Ubuntu 14.04 (also 12.04); Dell latitude E7440) I tried

sudo apt-get update && sudo apt-get install laptop-mode-tools

and changing GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=noirq" in /etc/default/grub

also tried the entries acpi=force apm=power_off there too. So far nothing has worked. will keep looking...
