Ubuntu 24.04 (but the issue was there before the upgrade as well)

When I login into my Ubuntu laptop, I see a +/- 2 minute wait where there is no activity at all (no CPU, no HD, blank screen with only a mouse pointer that can move).

I find nothing in the logs (dmesg, syslog, journal) to indicate that it is waiting for something.

This happens whether I login to Mate, Cinnamon or Gnome. No difference. Also I created a blank default new user and tried that. Same issue.

I guess it is waiting for network not responding?

How can I trace this issue and find where it is waiting for?

Using lightdm & intel driver.

I found a possible solution here: https://forums.linuxmint.com/viewtopic.php?p=2544317#p2544317 , and it worked for me.

The problem on my machine was related to me disabling ipv6 using sysctl. The solution was the following as can be read from the above link:

  • Remove the lines that disable ipv6 from /etc/sysctl.d/* or /etc/sysctl.conf
  • Edit /etc/default/grub, and add ipv6.disable=1" to the GRUB_CMDLINE_LINUX_DEFAULT parameter in that file
  • Run sudo grub-mkconfig -o /boot/grub/grub.cfg

Reboot after this and in my case the delay was gone.
