Package: gnome-shell Version: 3.14.4-1~deb8u1 Severity: important On one particular system, I've observed there is always a delay of about 20 seconds to unlock the screen. The logs don't contain any warning or explanation.
The delay occurs after typing the password and pressing enter. Two lines are logged in auth.log immediately after pressing enter: gdm-password]: pam_krb5(gdm-password:auth): user daniel authenticated as daniel@REALM gdm-password]: gkr-pam: unlocked login keyring Then I wait and eventually the desktop appears. No further log entries appear in any /var/log/* during or after the delay. These are the libpam packages on the system: libpam-ck-connector:amd64 0.4.6-5 libpam-gnome-keyring 3.14.0-1+b1 libpam-krb5:amd64 4.6-3+b1 libpam-modules:amd64 1.1.8-3.1+deb8u1+b1 libpam-modules-bin 1.1.8-3.1+deb8u1+b1 libpam-runtime 1.1.8-3.1+deb8u1 libpam-systemd:amd64 215-17+deb8u4 libpam0g:amd64 1.1.8-3.1+deb8u1+b1 libpam0g-dev:amd64 1.1.8-3.1+deb8u1+b1 I notice the CPU usage of the gnome-shell process rises briefly during the delay, momentarily reaching 20% and going back down again. Are there any other log files created by gnome-shell? Is there any other debugging I should enable to identify the root cause of this issue?
