Public bug reported:
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.
** Affects: linux (Ubuntu)
