[Bug 1552906] Re: System freezes after closing lid on Thinkpad X260

 

Hello,

The patch committed to 4.4.6-rc1,
https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=a21211672c9a1d730a39aa65d4a5b3414700adfb
(identical to https://git.kernel.org/cgit/linux/kernel/git/rafael/linux-
pm.git/commit/?h=bleeding-
edge&id=42341f87ba1bee4c5be95038c24abb69cbcf361a ) is newer than
https://bugzilla.kernel.org/attachment.cgi?id=209371&action=diff (the
one in comment #90 mentioned in c#28 here)

I've applied the newer patch successfully (with some chunk messages) to
4.4.0-14-lts-xenial and 4.4.0-15-lts-xenial on Trusty (T460 and T460s)
and 4.4.0-16 on Xenial (T460s). Reportedly the same problem affects X1
Carbon G4s
https://www.reddit.com/r/thinkpad/comments/48wp3o/x1_carbon_gen_4_ubuntu_minireview/
(and the Yoga 260 as mentioned in
https://bugzilla.kernel.org/show_bug.cgi?id=110941 ) The author says in
110941 "It should work for any 4.4 kernel"

The bug about the T460s is
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1561974 though I'm
not sure whether this would count as a duplicate or not given they're
different models.

Title:
  System freezes after closing lid on Thinkpad X260

Status in Linux:
  Unknown
Status in linux package in Ubuntu:
  Triaged

Bug description:
  My current Ubuntu version is 14.04.4 but I also tried 15.10.
  Regardless of the Ubuntu version there is a serious problem with my new Thinkpad X260 when it is in battery mode and I close and reopen the lid. The problem is not affecting the suspend mode as it still occurs when this mode is disabled.

  what I expect to happen: After closing the lid the screen goes off.
  When I open the lid again, screen goes on and I can use the laptop.

  what happens every time: When I close the lid the screen turns black.
  When I open the lid again the screen displays the system but it is
  frozen and does not react on input.

  Interestingly I can not reproduce this problem when the laptop is connected to an AC power source.
