Password problems on resume

English Install/Boot/Login
1

I updated last night (zypper dup, with standard repos plus VideoLan), and although most things seem fine I find that if the machine sleeps (eg. on lid close), when it resumes there is a password dialog (which there wasn’t before) and worse, it will not unlock the screen when I enter the correct password!

This is using KDE. I thought the resume password settings we in the power management configuration, but that seems to have moved?

Can anyone tell me where I can disable the resume password checking (or help fix the problem where my password isn’t recognised)?

Thanks.

Seems to be the well known permissions problem when using the deprecated pam_unix2.so.
I suppose the you cannot unlock the standard lock screen either?

There are two workarounds:

  • change your PAM configuration to use pam_unix.so (the default since at least openSUSE 13.1) instead of pam_unix2.so
  • make /usr/lib64/libexec/kcheckpass suid root, i.e. run “sudo chmod +s /usr/lib64/libexec/kcheckpass” (you probably should adjust /etc/permissions.local accordingly so that it survives updates…)

See also 931816 – KDE 5.2 plasma unlock failed, or several threads here in the forums…

Yes, this is in the screen locker settings now.

Thanks very much, that was indeed the problem. I found that there were five *.rpmnew files in /etc/pam.d which different from the real ones by “pam_unix.so” instead of pam_unix2.so and “try_first_pass”. So I copied the .rpmnew files over the real ones (there were backups anyway) and then everything seemed to be fixed.

I also changed the switch to not require the screen locker on resume, so thank for that too.
