Package: lightdm-gtk-greeter Version: 2.0.2-1 Severity: normal Dear Maintainer,
* What led up to the situation? Install Debian 9 amd64 Xfce on Dell Inspiron 6400 and update. Connect external monitor, switch screen to external monitor, close laptop lid. Add CPU Graphs and Action Buttons to Xfce panel. Enable Action Buttons -> Lock Screen button. Click on Lock Screen button. After a while, CPU fan goes to high speed. Unlock screen. CPU Graph indicates one CPU was pegged, but returned to normal after unlocking screen. * What exactly did you do (or not do) that was effective (or ineffective)?

'lightdm-gtk-greeter' is using 100 %CPU when screen is locked while using external monitor with laptop. * What outcome did you expect instead? %CPU should be at or near 0 for all COMMANDs. * Additional information: https://lists.debian.org/debian-user/2017/10/msg00379.html https://bugs.launchpad.net/lightdm-gtk-greeter/+bug/1635125 https://bugs.launchpad.net/ubuntu/+source/lightdm-gtk-greeter/+bug/1448214 https://bugs.launchpad.net/ubuntu/+source/lightdm-gtk-greeter/+bug/1509780 Thank you, David -- System Information: Debian Release: 9.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable') Architecture: amd64 (x86_64) Kernel: Linux 4.9.0-4-amd64 (SMP w/2 CPU cores) Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968), LANGUAGE=C (charmap=ANSI_X3.4-1968) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages lightdm-gtk-greeter depends on: ii libc6 2.24-11+deb9u1 ii libcairo2 1.14.8-1 ii libgdk-pixbuf2.0-0 2.36.5-2+deb9u1 ii libglib2.0-0 2.50.3-2 ii libgtk-3-0 3.22.11-1 ii liblightdm-gobject-1-0 1.18.3-1 ii libx11-6 2:1.6.4-3 Versions of packages lightdm-gtk-greeter recommends: ii adwaita-icon-theme [gnome-icon-theme-symbolic] 3.22.0-1+deb9u1 ii desktop-base 9.0.2+deb9u1 ii gnome-themes-standard 3.22.2-2 ii policykit-1 0.105-18 lightdm-gtk-greeter suggests no packages. -- no debconf information
