[Bug 1343543] Re: X stops responding to input after entering idle power saving (screen off)

 

Adam Skillen, the next step is to fully commit bisect the kernel in
order to identify the offending commit. Could you please do this
following https://wiki.ubuntu.com/Kernel/KernelBisection ?

Title:
  [Dell XPS 15 L502X] X stops responding to input after entering idle
  power saving (screen off)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  I recently upgraded from 12.04 to 14.04.  Since the upgrade I have
  been having issues with X freezing after the screen enters power
  saving.  The issue did not occur in 12.04.  If I boot up a raring or
  saucy kernel, the issue does not occur.  The 3.13 trusty, and 3.16
  utopic kernels are affected.  It also occured when I tested the latest
  mainline drm-intel-next and utopic-rc kernels.

  Symptoms:
  After waking the screen from power saving/screensaver, the primary display wakes but X stops responding to input (the mouse cursor can still move, but clicking has no effect).  Secondary display does not wake.

  Frequency/conditions:
  Occurs almost every time the screen enters power saving (possibly DPMS issue?)

  When did you first notice it:
  Immediately after upgrading to 14.04

  I followed the suggestions at this URL and tested a few kernels:
  https://wiki.ubuntu.com/X/Troubleshooting/Freeze

  The issue does NOT occur when running these older kernels:
    linux-image-3.8.0-42-generic (3.8.0-42.62~precise1)
    linux-image-3.11.0-24-generic (3.11.0-24.42~precise1)

  The issue does occur when running these kernels:
    linux-image-3.16.0-997-generic (3.16.0-997.201407120342)
    linux-image-3.16.0-031600rc5-generic (3.16.0-031600rc5.201407131735)
    linux-image-3.16.0-3-generic (3.16.0-3.8)
    linux-image-3.13.0-32-generic (3.13.0-32.56)

  Additional notes:
  I have a hybrid Intel/Nvidia GPU model (Nvidia optimus), however the error
  occurs whether or not I have invoked the discrete Nvidia card.

  I am running the most recent BIOS for my system.

  When running the 3.11 saucy kernel I still see error messages in dmesg
  after entering power saving, however X does not freeze.

  dmesg errors:
