I just upgraded to Debian Buster from Stretch.I am running it on an Acer Aspire V3-571 laptop. I am using XFCE Desktop Environment ( in Stretch I used it also ).In the Energy ... Settings I did set up in Stretch that that after 3 minutes of inactivity the screen comes blank and it works so far.But, from there I can't wake up the laptop, whatever I am doing: moving or clicking with the mice, hit Shift, Esc, Enter, Cursor Down or Up, these does not help to get back to my Desktop.The only way to get it back is to hold down the Power button until it is shutted down, then hit again Power button to start the laptop.I purge the apmd package, but that does not helped me out. How can I solve this problem?I had a similar problem on a different distro and I fixed it by just upping the brightness when it was asleep. Fn f6 on a Thinkpad to increase brightness.Instead of sleeping or hibernating sometimes the machine was just turning the screen brightness down...
I tried the Fn F6 too, but on my Debian Buster system this key combination is for show and switch between monitors.
Here the Fn Left decrease, Fn Right increase the screen brightness but that does not work either, probably because my external monitor - which is LG Flatron W2252TQ does not have such capability.
So, when my screen goes blank, I can't use Fn plus some keys to get my Desktop back.
But I just found the way: Ctrl+Alt+F1 to go to the Virtual Terminal, and from there Alt+F7 get me back to my Desktop.
But, is this the solution?Before, on Stretch I just hit a Shift key and get back my Desktop out there. But here, on Buster, this does not work. Why?
Moreover, I just purge the sleepd package, but install again all acpi packages. So I use Ctrl+Alt+F1 and then Alt F7 to get back my Desktop.
Is there a better way to do it? -- Best, Pali
