How to shorten unlock time in 22.04

  • 772

I'v just installed a fresh Ubuntu 22.04 on a Dell latitude 5480. Except for upgrading the packages, I haven't done anything - not even changing the driver (default is xorg).

When the screen is locked, e.g. after sleep or just lock (super+l), I type the correct password, it takes ~6 seconds to unlock.

Played with it a bit and found something strange: If I type a wrong password, I get the same 6 seconds delay (without the unlocking of course), but if I now enter the correct password, the unlock is immediate.

Something is causing the delay for the first time, regardless of the correctness of the password...

Any idea how to make the unlock faster? As I said before, the laptop is updated with the latest packages (sudo apt update + upgrade).

  1. I have the same issue as you when using wayland windowing system on Latitude 5500. It seems that the graphics card wasn't installed, as it is not yet available for ubuntu 22 (I hope it will be available soon), and from the answers I found seems like this would be the problem with Wayland.

    I just switched to xorg windowing system for now (but you loose all the cool trackpad features)

    This is the link from where I got the instructions on how to enable xorg. And also be able to switch between them on user login screen: https://linuxconfig.org/how-to-enable-disable-wayland-on-ubuntu-22-04-desktop

    Basically you need to do the following:

    sudo nano /etc/gdm3/custom.conf

    Set te WaylandEnabled variable to true and uncomment the line:

    WaylandEnable=true

    Then just restart the service:

    sudo systemctl restart gdm3

    After this, on the login screen where you insert your password, you will have the option to select - from the bottom right corner - the windowing system you want, so you should select "ubuntu xorg" instead of "ubuntu" which is Wayland.

    I hope this will help you with the problem until we eventually get a graphics card driver.

  2. Delete and clean up your os from garbage and unnecessary files. You should also check that any startup application which can be heavy to load or you have set more applications to startup as the os loads.

    You can use gui apps like spacer. install : sudo apt install stacer
