But this issue is reproducible with any clean bionic desktop install (since GDM needs to be the login managed). It is NOT reproducible if I switch back to lightDM. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gdm in Ubuntu. https://bugs.launchpad.net/bugs/1782152 Title: GDM blocks SIGUSR1 used in PAM scripts Status in gdm package in Ubuntu: Incomplete Bug description: In case of the following scenario: 1. PAM configured to run auth and session with pam_exec scripts synchronizing via SIGUSR1 2. Using GDM as the login manager causes SIGUSR1 never reaches the target scripts. Workaround: a) Use SIGUSR2 in the scripts. b) Comment out block_sigusr1() call in daemon/main.c. To reproduce add the following entries: /etc/pam.d/common-auth: auth optional pam_exec.so log=/tmp/auth.log expose_authtok quiet /usr/local/bin/auth.py /etc/pam.d/common-session: session optional pam_exec.so log=/tmp/session.log /usr/local/bin/session.py Attaching example scripts. When using SIGUSR1 - sigusr1_handler is never called, with SIGUSR2 it is called without issues.
