I also get this error on KDE, so it's not caused by lightdm.

Must be gnome-keyring then

Could also be PAM

The last error recorded in my journal before my system locked up:

`Sep 12 07:41:37 k3 lightdm[849]: gkr-pam: unable to locate daemon control file`

Unable to bring up a virtual terminal: Ctrl + Alt + F1, (F1-F6). Mouse frozen, etc.

Happens at random times.

Same behavior for XFCE and GNOME.

Will downgrade lightdm and try for a while to see if the system locks stop.

Kernel: 5.2.13-arch1-1-ARCH x86_64 bits: 64 compiler: gcc v: 9.1.0 Desktop: Xfce 4.14.1 Distro: Arch Linux
lightdm version: 1.30.0

After downgrading from lightdm 1.30.0 to 1.28.0 I have discovered that downgrading did not help. My system is still locking up with the same `Sep 14 15:07:03 k3 lightdm[852]: gkr-pam: unable to locate daemon control file` message.

Any recommendations on how best to troubleshoot this issue?
