suspend doesn't work on Dell Inspiron 1525

  • 772

I'm having a Dell Inspiron 1525. Suspend and resume were working correctly.

All of a sudden, when I click the suspend menu option the system doesn't get suspended. Instead, it is being locked. Viewing dmesg output reveals

In particular usbhid 6-2:1.0: suspend error -5. Google didn't find anything useful about that.

How can I further troubleshoot this matter?

    The line

    PM: Device 6-2 failed to suspend: error -5

    suggests that there is a problem with suspending with that device. You can find out what is on Bus 6.2 by doing lsusb and looking at that. If the problem persists, file a bug report with "ubuntu-bug linux"

  2. I think there might be clues earlier in the dmesg output.

    Do

    dmesg -T|grep Freez -A4

    to look for particular processes that stops suspend from suspending, does it give anything?

    In that case, see my answer here: How to make "suspend" option to work? on how to automatically kill them before suspend.
