Ubuntu 24.04.2 LTS Does not boot after update 03/24/2025 and how to fix?

Today an update came to Gnome. After update my computer become unresponsive at login screen.

I couldn’t find the exact cause, most likely new gnome libraries does not support old configuration files.

Here’s the solution that saved my day

First, i noticed no error messages shown on boot screen. It just stalls and displays which services has started. Then I checked SYSLOG but couldn’t find the cause.

But it is fixed after purging config files of GDM3 then re-install ubuntu-desktop packages.

Here’s how:

• First switch to another screen with CTRL+ALT+F5 for instance.
• Then log into your account with username and password

Then, remove GDM3.

sudo apt remove --purge gdm3

Now we need to reinstall gdm3. But, some packages related to gdm3 automatically removed. So we need to install whole ubuntu desktop packages. Like nautilus file manager for instance.

sudo apt install ubuntu-desktop

Then you can reboot your computer.

sudo reboot

It should be working now. I hope it helps.
