On a fresh install of juno on my laptop, when I try to unlock my session it takes between 30s and 2m to respond. I fill my password, sometimes I have to wait facing a black screen. Sometimes it shows the open windows, but none of the buttons and other UI elements are clickable, the time is wrong. I was having this problem with the beta release, but now with the stable on a claen installation the problem persists.
Some of my specs: (I'm using intel video card only)
