sorry, it happens while upgrading non-systemd _packages_, still on systemd systems.
still unclear to me which packages trigger it. at one point systemd appeared to be one that did, but apparently not always the case -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1428712 Title: Screen turns green and locks out during apt full-upgrade Status in systemd package in Ubuntu: Incomplete Bug description: Since updating to vivid, occasionally when doing an apt full-upgrade the screen will turn and stay bright green. I can see and move the mouse cursor but nothing else, and no system keyboard shortcuts appear to do anything (ctrl-alt-f1 through ctrl-alt-f7, ctl-alt-backspace, ctl-alt-delete, etc). Probably an issue with a specific package rather than apt, but not sure how to narrow it down. here's the list of packages that were upgraded the last time this happened, form /var/log/apt/history.log: Start-Date: 2015-03-05 07:47:15 Commandline: apt full-upgrade Install: console-setup-linux:amd64 (1.108ubuntu3, automatic) Upgrade: python3-apparmor:amd64 (2.9.1-0ubuntu5, 2.9.1-0ubuntu6), apparmor-easyprof:amd64 (2.9.1-0ubuntu5, 2.9.1-0ubuntu6), glib-networking-common:amd64 (2.43.1-1, 2.43.91-1), libgail18:amd64 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1), libgail18:i386 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1), libsoup2.4-1:amd64 (2.49.1-1ubuntu1, 2.49.91.1-1), libsoup2.4-1:i386 (2.49.1-1ubuntu1, 2.49.91.1-1), libwagon-java:amd64 (1.0.0-2ubuntu2, 1.0.0-5), libgeis1:amd64 (2.2.16+14.04.20140303-0ubuntu1, 2.2.16+15.04.20150304-0ubuntu1), console-setup:amd64 (1.70ubuntu11, 1.108ubuntu3), libsoup2.4-dev:amd64 (2.49.1-1ubuntu1, 2.49.91.1-1), libapparmor1:amd64 (2.9.1-0ubuntu5, 2.9.1-0ubuntu6), gtk2-engines-pixbuf:amd64 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1), gtk2-engines-pixbuf:i386 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1), libglib2.0-0:amd64 (2.43.90-1, 2.43.91-1), libglib2.0-0:i386 (2.43.90-1, 2.43.91-1), libglib2.0-dev:amd64 (2.43.90-1, 2.43.91-1), libgtk2.0-bin:amd64 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1), libgtk2.0-com mon:amd64 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1), gir1.2-gtk-2.0:amd64 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1), libglib2.0-data:amd64 (2.43.90-1, 2.43.91-1), libflac8:amd64 (1.3.0-3, 1.3.1-1ubuntu1), libflac8:i386 (1.3.0-3, 1.3.1-1ubuntu1), libsoup-gnome2.4-1:amd64 (2.49.1-1ubuntu1, 2.49.91.1-1), libsoup-gnome2.4-1:i386 (2.49.1-1ubuntu1, 2.49.91.1-1), libnm-util2:amd64 (0.9.10.0-4ubuntu8, 0.9.10.0-4ubuntu9), libapparmor-perl:amd64 (2.9.1-0ubuntu5, 2.9.1-0ubuntu6), libnm-glib-vpn1:amd64 (0.9.10.0-4ubuntu8, 0.9.10.0-4ubuntu9), libdee-1.0-4:amd64 (1.2.7+14.04.20140324-0ubuntu1, 1.2.7+15.04.20150304-0ubuntu1), libgtk2.0-0:amd64 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1), libgtk2.0-0:i386 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1), libglib2.0-0-dbg:amd64 (2.43.90-1, 2.43.91-1), gir1.2-dee-1.0:amd64 (1.2.7+14.04.20140324-0ubuntu1, 1.2.7+15.04.20150304-0ubuntu1), keyboard-configuration:amd64 (1.70ubuntu11, 1.108ubuntu3), kbd:amd64 (1.15.5-1ubuntu1, 1.15.5-1ubuntu2), libx264-142:amd64 (0.142.2431+gita5831aa -1ubuntu1, 0.142.2495+git6a301b6-1ubuntu1), apparmor:amd64 (2.9.1-0ubuntu5, 2.9.1-0ubuntu6), libglib2.0-bin:amd64 (2.43.90-1, 2.43.91-1), python3-libapparmor:amd64 (2.9.1-0ubuntu5, 2.9.1-0ubuntu6), network-manager:amd64 (0.9.10.0-4ubuntu8, 0.9.10.0-4ubuntu9), gir1.2-networkmanager-1.0:amd64 (0.9.10.0-4ubuntu8, 0.9.10.0-4ubuntu9), glib-networking-services:amd64 (2.43.1-1, 2.43.91-1), libgtk2.0-dev:amd64 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1), glib-networking:amd64 (2.43.1-1, 2.43.91-1), glib-networking:i386 (2.43.1-1, 2.43.91-1), gir1.2-soup-2.4:amd64 (2.49.1-1ubuntu1, 2.49.91.1-1), dh-apparmor:amd64 (2.9.1-0ubuntu5, 2.9.1-0ubuntu6), libnm-glib4:amd64 (0.9.10.0-4ubuntu8, 0.9.10.0-4ubuntu9), libgail-common:amd64 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1), libgail-common:i386 (2.24.26-0ubuntu2, 2.24.27-0ubuntu1) ProblemType: Bug DistroRelease: Ubuntu 15.04 Package: apt 1.0.9.3ubuntu1 ProcVersionSignature: Ubuntu 3.19.0-7.7-generic 3.19.0 Uname: Linux 3.19.0-7-generic x86_64 NonfreeKernelModules: nvidia wl ApportVersion: 2.16.2-0ubuntu1 Architecture: amd64 CurrentDesktop: GNOME Date: Thu Mar 5 08:00:19 2015 InstallationDate: Installed on 2014-02-24 (373 days ago) InstallationMedia: Ubuntu-GNOME 14.04 "Trusty Tahr" - Alpha amd64 (20140218) ProcEnviron: TERM=xterm PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash SourcePackage: apt UpgradeStatus: Upgraded to vivid on 2015-02-04 (28 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/systemd/+bug/1428712/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
