So, KDE is now becoming good as Gnome in becoming entwined with systemd. I can see myself ending up in working on VTs only soon! ;-p -- Regards, Mick signature.asc Description: This is a digitally signed message part.

Are you updating KDE? I always run into this issue when updating KDE, so I now turn off the screen lock before I commence updating. If this is a default Gentoo installation with openrc, why does a default plasma desktop screenlocker comes up with this nonsense? Because KDE expects people to use systemd, a bug was raised regarding this issue, and the developers basically said you're on your own (RESOLVED: WONTFIX): https://bugs.kde.org/show_bug.cgi?id=360489 According to a comment in the bug, you can try to figure out which session it is (ck-list-sessions) and look for the X11 display property set. This will not work (or could be difficult) if you have several users using KDE at the same time and can't tell the sessions apart. Once you figure that out, remember the session name and: # su -c 'dbus-send --system --print-reply \ --dest="org.freedesktop.ConsoleKit" \ /org/freedesktop/ConsoleKit/ \ org.freedesktop.ConsoleKit.Session.Unlock' This worked on my laptop running openrc. I now just disable the locker before doing updates. Dan

Thanks Stroller, but no, this PC never had any systemd component, on purpose: # emerge -pN world These are the packages that would be merged, in order: Calculating dependencies... done! I had disabled USE flag 'systemd' in make.conf as soon as this flag was established: $ euse -I systemd global use flags (searching: systemd) local use flags (searching: systemd) [- c] systemd (dev-qt/qtcore): Enable native journald logging support [- c] systemd (media-sound/pulseaudio): Build with sys-apps/systemd support to replace standalone ConsoleKit. [- c] systemd (sys-apps/accountsservice): Use sys-apps/systemd instead of sys-auth/consolekit for session tracking [- c] systemd (sys-apps/busybox): Support systemd [- c] systemd (sys-apps/dbus): Build with sys-apps/systemd at_console support [- c] systemd (sys-auth/pambase): Use pam_systemd module to register user sessions in the systemd control group hierarchy. [- c] systemd (sys-auth/polkit): Use sys-apps/systemd instead of sys-auth/consolekit for session tracking [- c] systemd (sys-fs/udisks): Support sys-apps/systemd's logind The interesting thing is I never enabled screen locking, so plasma ought to be running with default settings. If such a setting causes the session to become inaccessible it should have been disabled by default. There may have been a warning about it in the past, but I can't recall it. The funny thing was the user thought her machine was being hacked! o_O I tried to pacify her by explaining that without systemd stack the attack surface should be smaller. ;-p -- Regards, Mick signature.asc Description: This is a digitally signed message part.
Re: [gentoo-user] Unlocking Plasma desktop in Gentoo without systemd
I had a similar (if not identical problem). This solution is a "difficult" solution, the reason I experienced this (if I understand) was that I was running KDE at the same time I was updating KDE. I can't remember if I simply rebooted, or if all it took was logging out, and logging back in. Even if I had rebooted, the *most* that should be required is restarting X, which if you are running XDM may require restarting XDM, or as stated, simply logging out and logging back in (but that might not be possible from KDE running in this broken mode). It should happen relatively infrequently. If you are doing unattended updates, you are likely to run into this kind of problem from time to time. I do not recommend it except for "security" updates, which I don't believe there is an automated process in Gentoo to do. Ie. I don't believe Portage flags updates as "security" updates in any way, so a single command of "emerge --update --security-only @word" (to my knowledge) isn't really a possibility. Though, also, I haven't been following recent discussions that closely, and I only recently returned to Gentoo after about 10 years away.

Is it possible some of your KDE components were emerged with USE="systemd"? Try something like `emerge -pN world`? Stroller.
[gentoo-user] Unlocking Plasma desktop in Gentoo without systemd
I started a plasma session and after some period of input inactivity I noticed the screen blanked out. Later on I moved the mouse and to my surprise I obtained this message: * "The screen locker is broken and unlocking is not possible anymore.
