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.
