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. --- ApportVersion: 2.14.1-0ubuntu3.19 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: simon 1437 F.... pulseaudio CurrentDesktop: Unity DistroRelease: Ubuntu 14.04 HibernationDevice: RESUME=UUID=76bcd0ad-fc42-4d1a-8089-0f10d23df682 InstallationDate: Installed on 2016-03-03 (0 days ago) InstallationMedia: Ubuntu 14.04.4 LTS "Trusty Tahr" - Release amd64 (20160217.1) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 138a:0017 Validity Sensors, Inc.
