Login problem after update to 20 ( MATE DESKTOP)

I upgraded Calculate linux from 18.12 to 20 MATE DESKTOP
But when i restart computer lightdm manu is showing. I put my login and password and I HAVE to WAIT ABOUT 3-4 minutes after Mate desktop load.
Output with errors from log files.:

  1. /var/log/messages
    "pam_ldap: missing file “/etc/ldap.conf”
  2. /var/log/x-0-greeter.log
    (process:3565): WARNING **: Error getting XDG_RUNTIME_DIR from ConsoleKit: GDBus.Error:org.freedesktop.ConsoleKit.Session.Error.Failed: Failed to create the XDG_RUNTIME_DIR
  3. /var/log/x-0.log
    The XKEYBOARD keymap compiler (xkbcomp) reports:

Warning: Unsupported high keycode 372 for name ignored
X11 cannot support keycodes above 255.
This warning only shows for the first high keycode.
Errors from xkbcomp are not fatal to the X server

  1. /var/log/lightdm.log - no errors…

What is wrong ???

I have installed LXDE nad it starts immediately.
It not lightdm problem becuse replaced it to sddm and problem still exist on sddm.
Any Idea? can someone help?

I also did. :
chown username:username .Xauthority

sudo mv ~/.Xauthority ~/.Xauthority.backup
Help nothing

I have found the reason of problem
gnome-keyring-daemon could’nt set environment varible in session - timeout

that is the piont when lightdm hangs

masked gnome-keyring 3.31.91-r1
installed gnome-keyring 3.28.2
now works !
