After a few minutes without doing something on the PC, Antergos turns into a lock screen. So far, so good.
But the lock screen is black. Therefore I could not type my password, becaus I see nothing.
Interesting is, when I put the LOOKED Antergos on the task bar and wait a few minutes, the look screen is normal again. This is really uncomfortable and impractical when I will work with my PC at the time, I want to work with. Not after a few minutes after looking the screen an put it on the task bar… ;-)
I have this problem since two months.
I use Xfce.
I don’t know, if this would be an antergos-problem or a vbox-problem.
This info is also in the virtualbox-forum: -> viewtopic.php?f=3&t=91845 (I could not post URLs)
Best regards to you.
