Hi, sorry to bug you again. I let the laptop with external HDMI enabled and internal LCD disabled. After a while external HDMI felt asleep into stand-by mode. But, I could not wake up a screen when touching my keyboard. Not even ctrl+alt+f1 helped (which usually brings me into framebuffer console out off the X11 windows and hence wakes up my screen). Alt+SysRq+S seemed to trigger some disk activity at least. The trick which worked was to close the lid and open again. That at least woke up the internal LCD of the laptop. Although it so far feels like a bug in this case it was better than nothing.
