Multiseat login issue

  • 772

I have created a multi seat Ubuntu 16.04 and separated the devices to two seats.

I was able to login to the first seat i.e., seat0 without any issues do the work in it.

While coming to second seat i.e., seat1 i am not able to login and it is showing as Retry "Failed to authenticate" for every user. but with the same user i am able to login in seat0.

Please help us or guide resolve the above issue.

Thanks in advance.

  1. It looks like it is a bug in the newer version of lightdm (1.18.2). Try to downgrade to the previous version using:

    sudo apt install lightdm=1.18.1*
echo "lightdm hold" | sudo dpkg --set-selections

    Obs: The last line puts lightdm on hold to avoid upgrades to the 1.18.2 version. Once the newer version is fixed you want to re-allow the upgrade by using 

    echo "lightdm install" | sudo dpkg --set-selections

    Maybe the related bug is this one:
