I have kinda fast laptop Dell XPS 13 with SSD

Computer loads and works really fast, but when I see GDM screen, enter user credentials I have a delay about 40 sec.

If I lock the screen when everything is loaded and will try to unlock it I will have the same 40 sec delay.

Don't see anything wrong at dmesg

    Likely a PAM issue. Are you using Samba domains?

  • nope, haven't used it ever. Just uninstalled samba that was installed by default, locked the screen and still the same issue

  • I'm also having this issue in 17.10, though I'm using X11.

  • Same problem. I thought it Wayland's fault, switched to X11, still same problem, at least 30 secs to be able to pass the lock screen :-( I don't have encryption on my home, nor any Samba shares. Feb 15, 2018 at 8:41

Judging by your logfile, some extensions seem to block your login process.

For example @ 13:04:30 6 seconds have passed for EasyScreenCast, then another 6 seconds go by for this extension.

Disabling individual extensions

You can disable individual extensions via the commandline
looking up the names of the extensisons with

ls ~/.local/share/gnome-shell/extensions

and disabling them with

gnome-shell-extension-tool -d <extension-name>

or from gnome-tewak-tool

enter image description here

Disabling all extensions

You can also go Tabula Rasa and delete all extensions

rm -rf .local/share/gnome-shell/extensions

You can find more infos on handling of extensions on the official gnome3 wiki, here.

  • After deactivating everything, then reactivating each externsion one by one, I found the culprit. It was the Easyscreencast extension! Thanks Robert! Feb 21, 2018 at 14:50
