http://bugzilla.opensuse.org/show_bug.cgi?id=1205768 Bug ID: 1205768 Summary: Plasma Lockscreen and pam_u2f: Unlock needed for each monitor? Classification: openSUSE Product: openSUSE Tumbleweed Version: Current Hardware: Other OS: Other Status: NEW Severity: Normal Priority: P5 - None Component: KDE Workspace (Plasma) Assignee: opensuse-kde-bugs@opensuse.org Reporter: opensuse_buildservice@ojkastl.de QA Contact: qa-bugs@suse.de Found By: --- Blocker: --- Hi, current openSUSE Tumbleweed on a X86_64 Laptop KDE Plasma (X11, not wayland) pam_u2f-1.2.1-1.2.x86_64 I am using pam_u2f to unlock my Plasma/KDE lock screen using a U2F device (the predecessor of FIDO). PAM configuration for sudo and sudo-i: ``` # etc/pam.d/sudo #%PAM-1.0 auth sufficient pam_u2f.so authfile=/etc/Yubico/u2f_keys cue [...] ``` PAM configuration for KDE unlocking (with openasuser, so it checks for the user that is logged in) ``` # /etc/pam.d/kde #%PAM-1.0 auth sufficient pam_u2f.so openasuser [...] ``` Works like a charm with sudo. Enter "sudo ls", the device starts blinking, I confirm and the command is executed. Works like a charm with the lockscreen, if the laptop is NOT connected to an external monitor. - plasma is locked - I move the mouse - the U2F device starts blinking - I touch the U2F device and confirm - the blinking stops - I get a "Entsperren" (Unlock) button instead of the password prompt on the lock screen - I press that button or hit ENTER - the screen is unlocked Works with two external monitors connected, but it seems I need to go through the "press U2F device and click the 'unlock' button" process for each monitor. In my case, three times. Sometimes it seems to be enough to just have 2 of each, however: Once should be enough. - plasma is locked - I move the mouse - the U2F device starts blinking - I touch the U2F device and confirm - the blinking stops - I get a "Entsperren" (Unlock) button instead of the password prompt on the lock screen - I press that button or hit ENTER - **the lock screen stays, the device starts blinking again** - I touch the U2F device and confirm - the blinking stops - I get a "Entsperren" (Unlock) button instead of the password prompt on the lock screen - I press that button or hit ENTER - **the lock screen stays, the device starts blinking again** - I touch the U2F device and confirm - the blinking stops - I get a "Entsperren" (Unlock) button instead of the password prompt on the lock screen - I press that button or hit ENTER - the screen is unlocked Not sure if there are any logs that I can provide?
