Slow boot on Ubuntu 21.04 (installed twice, same problem)

eg flag

I installed Ubuntu 21.04 yesterday (dual booting with Windows 10) with an SSD (Samsung 970 EVO), Nvidia GPU and AMD CPU. Ubuntu takes >30 seconds to reach the login screen after selecting it on the boot menu and this is significantly longer than Windows 10 which takes <5 seconds. My BIOS splash screen also seems to be taking >10 seconds to load which is notably longer than usual. I've tried these commands to troubleshoot:

I've tried the changes below but I've had no success so far:

  • modifying /etc/default/grub with GRUB_CMDLINE_LINUX_DEFAULT="quiet splash noresume" and updating grub
  • modifying /etc/default/grub with GRUB_CMDLINE_LINUX_DEFAULT="nomodeset" and updating grub
  • checking that the nvidia proprietary drivers are installed (tried nvidia-driver-470 and nvidia-driver-460)

Edit: Unplugging all my USB devices (and HDMI EDID emulator) and plugging them back in again seems to have fixed all my issues. I will do some more testing to verify this. Thanks @CharlesGreen for the suggestion.

Can you append the output of `systemctl status upower` to your question?
eg flag
@CharlesGreen: Edited my post to include it.

Sadly, were about at the limit of my meager abilities. You might examine `journalctl "_SYSTEMD_UNIT=upower.service"` to see if there are any extraneous error messages, and also unplug any USB devices that you can from your computer and boot again.

@CharlesGreen: Unplugging all my USB devices (and my HDMI EDID emulator) and plugging them in again seems to have done the trick...I will have to look into what made the difference. It seems all fixed now (both the slow BIOS splash screen and Ubuntu start-up) but I will do some more testing to verify it. Thanks a lot!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
