Stuck on Ubuntu Installation & Trial - Started Dispatch Password Requests

Question

I am trying to install Ubuntu on a decent laptop. I am installing through a USB and had no errors come up during the disk check.

Initially it would just hang on the loading screen, so I then removed splash and quiet from the start-up command.

The very last line before hanging/freezing is:

[OK] Started Dispatch Password Request to Console Directory Watch.

Any help?

Answer 1

Add intel_idle.max_cstate=1 as a boot parameter.

(This assumes you're trying to install Ubuntu 16.04 and your laptop has an Intel Bay Trail processor.)

I ran into this too installing Ubuntu Server 16.04 on an Intel NUC NUC5CPYH with a quad-core Bay Trail processor. I edited boot parameters by following these instructions and it booted all right after that.

Answer 2

Adding the following boot parameters worked for me on a NUC5CPYH with 2016-12 BIOS:

usbcore.autosuspend=-1 processor.max_cstate=1 intel_idle.max_cstate=0

You can boot by pressing "e" on the grub boot menu, and adding these parameters to the end of the line starting with linux. Then once in, you can edit /etc/defaults/grub to add the same parameters permanently:

GRUB_CMDLINE_LINUX_DEFAULT="usbcore.autosuspend=-1 processor.max_cstate=1 intel_idle.max_cstate=0"

Then do a sudo update-grub and you're ready to go.
