I'm new in the world of Linux and using Ubuntu 14.04 LTS version.
My question is how to make the 'Suspend' option work?
Whenever I click that option from my laptop, the screen becomes black at first, then my login screen comes after 2-3 seconds.
Nothing happens after that.
I don't know what exactly happening. I made some changes as per this Ubuntu Forum thread.
Then I checked the suspend log, which shows:
Running hook /etc/pm/sleep.d/20_custom-ehci_hcd suspend suspend:
/etc/pm/sleep.d/20_custom-ehci_hcd: 21: /etc/pm/sleep.d/20_custom-ehci_hcd: cannot create /sys/bus/pci/drivers/ehci_hcd/unbind: Directory nonexistent

/etc/pm/sleep.d/20_custom-ehci_hcd suspend suspend: Returned exit code 2.

Thu Aug 20 19:59:44 IST 2015: Running hooks for resume
Running hook /etc/pm/sleep.d/10_unattended-upgrades-hibernate resume suspend:
/etc/pm/sleep.d/10_unattended-upgrades-hibernate resume suspend: success.
I then just deleted /etc/pm/sleep.d/20_custom-ehci_hcd. Now it works perfectly.
Someone please explain the reason for this behaviour.
Open your command line (terminal) and enter this command to edit the config file:
sudo -H gedit /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
Copy and paste below lines into the file and save it.
[Re-enable hibernate by default in upower]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes
[Re-enable hibernate by default in logind]
Identity=unix-user:
Action=org.freedesktop.login1.hibernate
ResultActive=yes
After reboot it will work. (I too have same bug but in my case for hibernate too)
