It appears the problem is related to lightdm and PAM: Mar 25 23:26:07 zlink2 lightdm[840]: PAM unable to dlopen(pam_kwallet.so): /lib/security/pam_kwallet.so: cannot open shared object file: No such file or directory Mar 25 23:26:07 zlink2 lightdm[840]: PAM adding faulty module: pam_kwallet.so Mar 25 23:26:07 zlink2 lightdm[840]: PAM unable to dlopen(pam_kwallet5.so): /lib/security/pam_kwallet5.so: cannot open shared object file: No such file or directory Mar 25 23:26:07 zlink2 lightdm[840]: PAM adding faulty module: pam_kwallet5.so Mar 25 23:26:07 zlink2 lightdm[840]: pam_succeed_if(lightdm:auth): requirement "user ingroup nopasswdlogin" not met by user "derk"
I'm not sure if this is a problem specific to lightdm, or a general PAM problem that would affect gdm3 in normal Ubuntu too. Please look into the causes of the above errors on your machine. ** Package changed: ubuntu => lightdm (Ubuntu) ** Changed in: lightdm (Ubuntu) Status: Incomplete => New ** Package changed: lightdm (Ubuntu) => kwallet-pam (Ubuntu) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1821609 Title: Xorg freeze - fails to start or stay going screen blanks-grub seems involved To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/kwallet-pam/+bug/1821609/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
