I tried to configure this mode for my laptop (since I'm used to this functionality on windows)
As per the wiki page I tried to reconfigure the
/etc/systemd/sleep.conf - my laptop stopped to suspend at all.
As per what the file said "to restore the defaults - just delete the file" - I have done exactly that, but now I don't have any source file to work upon. (since I thought it would generate a new one on reboot)
I created my own one from scratch. Playing around - i found out that
is causing the laptop to fail to go to suspended state (the cursor remains on the screen, but everything else goes black)
