Not sure what has changed recently. I’ve not installed anything new, just updates. When I close the laptop the screen shuts off, but when I open it later, no screen. The laptop is clearly on, but nothing I do seems to wake it. I must use the power button to shutdown. Then, I have to turn it back on. I tried tweaks suggested in A little question! but changes in logind.conf didn’t seem to fix it.
Ideas and thoughts would be appreciated. Of course, the screaming fast boot time of AL makes this issue less of a bother. I am just wondering what happened. I should probably boot to OS X and double check it isn’t hardware.
