 |
|
When I lock screen with xscreensaver, then I have to manually kill it from a tty as it always say login failed.
Reading over the internet, there are ubuntu solutions like changing /etc/shadow permissions, but I have no clue of what is really happenning here.
My current permissions are:
ls -lh /etc/shadow
-rw-r----- 1 root root 859 ago 14 13:22 /etc/shadow
Is there anything (else) I can so? As I don't like to set dangerous permissions on things like this one, or maybe it is not related at all?

xscreensaver is broken here too.
Keyboard and mouse events do not reset the lock timer of xscreensaver. |

| The "new-login" USE-flag makes it pull the lightdm package which I do not need. Is it really necessary? |

/etc/shadow should be 0400. And xscreensaver doesn't need to read /etc/shadow. Xscreensaver relies on PAM (if installed, of course... But it is, no ?) to determine if a user is authorized to unlock it or not. |
