24.04 on Lenovo Legion Pro 5i hangs on filesystem check

[ray field]

Couple months ago installed Ubuntu 24.04 on a new Lenovo laptop (Legion Pro 5i Gen 8 Intel (16") with RTX 4050), which went well until one of the updates three or so weeks ago. Since then, most often when I power up I get the "Press Ctrl+C to cancel all filesystem checks in progress," on which bootup hangs. I can successfully boot after either, 1) using grub to start Windows, then exiting and restarting, or 2) booting from thumb drive and running boot-repair - however, almost inevitably, once I shut down from Ubuntu, I get the filesystem check hang again and have do the workaround. What can I do to resolve?

Boot successfully repaired.

You can now reboot your computer.
Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 24.04.1 LTS entry (nvme0n1p1/efi/ubuntu/grubx64.efi file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\ubuntu\grubx64.efi

Anyone have any ideas? Is this a hardware-specific issue?

[tea for one]

Are you comfortable adding a parameter to Grub?
Try adding fastboot as below

sudo nano /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash fastboot"

sudo update-grub

Any improvement?

I'm comfortable messing with grub, except ten minutes of searching hasn't given me confidence about the "fastboot" parameter, problem is the results all seem to be about en/disabling fastboot in the BIOS.

What's also so perplexing about this issue is that the fastest way to get started is to boot Windows - when I restart from there I never have a problem getting back into Ubuntu. Booting from thumb drive and running boot-repair also does it but of course takes almost ten minutes.

Below is a boot-repair "report-only"

============================= Boot Repair Summary ==============================




Default settings: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub-efi of
nvme0n1p6,
using the following options:  nvme0n1p1/boot/efi
Additional repair would be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 24.04.1 LTS entry (nvme0n1p1/efi/****/grub****.efi (**** will be updated in the final message) file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\****\grub****.efi (**** will be updated in the final message)

User settings: _________________________________________________________________

modprobe: FATAL: Module efivars not found in directory /lib/modules/6.8.0-45-generic
Please backup your data before this operation.
The settings chosen by the user will reinstall the grub-efi of
nvme0n1p6,
using the following options:  nvme0n1p1/boot/efi
Additional repair will be performed: unhide-bootmenu-10s use-standard-efi-file restore-efi-backups

Please do not forget to make your UEFI firmware boot on the The OS now in use - Ubuntu 24.04.1 LTS entry (nvme0n1p1/efi/ubuntu/grubx64.efi file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.

[tea for one]

I'm comfortable messing with grub, except ten minutes of searching hasn't given me confidence about the "fastboot" parameter, problem is the results all seem to be about en/disabling fastboot in the BIOS.

There are three similar "fast" configurations:-
Fast Start Up (Windows system setting)
Fast boot (UEFI setting)
fastboot (grub setting to prevent file system check at boot) e.g.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash fastboot"

Try the setting, you can always remove it if it does not help you.

<sheepish look>
Worked. Sorry for doubting you, and thanks for having the patience/indulgence to repost. The main reason for my reluctance was that I wasn't sure I could run update-grub from USB boot in case fastboot borked my setup. I would still like to understand how this very peculiar issue arose - it's just counterintuitive, to say the least, that booting Windows would fix a Linux configuration issue, otoh after twenty-some years of Ubuntu I've learned to tolerate ambiguity.

There are three similar "fast" configurations:-
Fast Start Up (Windows system setting)
Fast boot (UEFI setting)
fastboot (grub setting to prevent file system check at boot) e.g.

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash fastboot"

Try the setting, you can always remove it if it does not help you.

Having added fastboot parameter to grub, file system check is now ignored.
I suggest that you boot into a "Try Ubuntu" live session and check the file systems - better to be safe than sorry.

[ray field]

Unfortunately I'm afraid the fastboot parameter has not resolved the issue.

Boot-repair says

modprobe: FATAL: Module efivars not found in directory /lib/modules/6.8.0-47-generic

However, running boot-repair to actually fix it doesn't work.

Messing with this sort of low-level plumbing freaks me out a bit cause I really don't want to have to bork things up so badly I can't boot at all. Suggestions?

[oldfred]

Ignore modprobe error. You have a valid UEFI "ubuntu" boot entry so it does not need to add it or update it.
Some issue between modprobe, grub & Boot-Repair with some configurations.
efivars are really here, not in a kernel folder.
folder with efivars:
ls /sys/firmware/efi/vars

You do show "ubuntu" entry in UEFI 0003 as first in boot order.
Does that change when Ubuntu does not boot?
sudo efibootmgr -v # note older versions needed -v to see details. Now -v gives too much detail, so whether you need it or not will depend on version of Ubuntu & efibootmgr.

Can you directly boot Ubuntu from UEFI one time boot entry?
Or do you need to go into system settings and change boot order there. HP needs that, have not seen it with Lenovo, but different models have different settings.

Prefer you just post link to Boot-Repair report as easier to flip tabs than scroll up & down to review report.

Have you installed nVidia drivers from Ubuntu repositories?

To put a period on this: Shortly after installing Ubuntu 24.04 on this laptop, and finding myself frustrated with gnome for some reason, I tried installing Unity because I was a fan once upon a time - however, it wasn't to my liking, so I uninstalled and purged it - or so I thought, however some traces remained - including the Unity label on the bootup screen.

Suspecting it was some remnant causing my problem, I grepped "unity" in installed packages and began deleting what I could - turns out quite a few things depend on Unity libraries and whatnot. However, I did succeed in removing these packages

libunity-protocol-private0
libunity-misc4
libunity-core-6.0-9
libunity-control-center1

and apparently one of these was behind the bootup hang, cause without these the problem seems to have disappeared, more or less - only issue seems to be if I press Enter to select the default Ubuntu entry when the grub screen appears, it tends to hang - which I'm more or less ok with, beats having to boot/exit into and out of Windows every time I want to use the laptop.
