After laptop lid is closed is subsequently opened again the system is unresponsive ,keyboard does`t respond and also mousepad does`t respond . Must restart the laptop in order to get it back working again. So far the only solution i know to avoid this issue is to set to "do nothing" when lid is closed in power management options instead of the default "suspend" when lid is closed . Already ready in the forums that more people have experience this bug My laptop is a Lenovo G710
Please report this to the bug tracker of your distribution. It might be caused by buggy OpenGL drivers not working correctly after resume from suspend, or by regressions in the kernel.
