Ubuntu – Ubuntu freezes/crash after wake when upgraded to 13.10


Back on 13.04 it didn't occurred.
I've upgraded to 13.10, systems apparently working fine, but, when I put it to sleep(using or not using extended monitor) and try to wake up, I see the screen(both), without lock-screen, but completely freeze, Neither tty open, nor the keyboard works.

So, only option remains is to force shut-down.
Any clue how to investigate the cause or fix it?
Thanks in advance, any info that'll help you could ask!

Ubuntu 13.10 x64 - not a fresh install/upgraded - with Unity
Dell Vostro 3550
AMD Proprietary Drivers - 13.11 / Hybrid with Intel 

——————— EDIT ————————

The fix has gone, i cant wake from suspend again, and, every time i shutdown/power up, i got like 9 windows from "report problem".
this is the error:

Actually there is a bug which you can find in Launchpad.net

Best thing is that there is also a patch through which you can solve this issue.

Follow these steps hope it works for you also:

  • Open terminal and execute these steps:

    sudo cp /etc/default/grub /etc/default/grub_back

    taking the backup of original /etc/default/grub file, in case some error occurs we can get back to original state

    sudo gedit /etc/default/grub

    opening the file in gedit to make the changes.

    Once file opened replace following line :


    to the line:

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pcie_aspm=force"

    Save the file Ctrl+S and close Ctrl+Q

Note: The next line to the line mentioned above should be GRUB_CMDLINE_LINUX="" not GRUB_CMDLINE_LINUX="acpi_osi=Linux"

  • Now execute following command to update the grub

    sudo update-grub
  • Re-start your system once.

Note: If you have trouble in brightness also and above method doesn't fix it then you can test by adding these lines in place I mentioned above.

2. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset"


3. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor pcie_aspm=force"


4. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor"


5. GRUB_CMDLINE_LINUX_DEFAULT="pcie_aspm=force"


6. GRUB_CMDLINE_LINUX_DEFAULT="quiet splash pci=nomsi"

Note: You have to do a sudo update-grub and a system restart every time you change the grub file

Different system would need different options, if any of the option works, I request to mention that in the comment.
