I have a Thinkpad L520 which had this problem in 12.10. I have also had this problem on an Asus machine a while back. I tried the solution I found for the Asus on my Thinkpad and it worked. This is what I did:
Create a file /etc/pm/sleep.d/20_custom_ehci_hcd containing: #!/bin/sh # File: "/etc/pm/sleep.d/20_custom-ehci_hcd". case "${1}" in hibernate|suspend) # Unbind ehci_hcd for first device 0000:00:1a.0: echo -n "0000:00:1a.0" | tee /sys/bus/pci/drivers/ehci_hcd/unbind # Unbind ehci_hcd for second device 0000:00:1d.0: echo -n "0000:00:1d.0" | tee /sys/bus/pci/drivers/ehci_hcd/unbind ;; resume|thaw) # Bind ehci_hcd for first device 0000:00:1a.0: echo -n "0000:00:1a.0" | tee /sys/bus/pci/drivers/ehci_hcd/bind # Bind ehci_hcd for second device 0000:00:1d.0: echo -n "0000:00:1d.0" | tee /sys/bus/pci/drivers/ehci_hcd/bind ;; esac Set it 755 and owned by root. Now the display returns after sleep without problems. -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/966744 Title: [i965] Resume from suspend leaves me with black screen or a screen of the desktop before it suspended.
