[SOLVED] 22.04 Boot stops just before KDE starts

[oshunluvr]

I had nVidia cards for years and learned how to manager their drivers. My last one died in 2020 and I switched to AMD. My life has definitely been easier since.

[ralfheinz]

BINGO! I can boot now with all three options!

I did it with the first mentioned line:

sudo ubuntu-drivers install nvidia:390

and then tried

dkms status

which led to the exact same result as you, oshunluvr predicted. I saw your response only after doing the install with the code from Schwarzer Kater . I guess the difference is that linux-modules-nvidia-390-5.19.0-46-generic installs only one component, while nvidia:390 installed approximately hundred or more.

I want to thank you all a thousand times. You deeply impressed me with your profound knowledge as well as your friendliness and your patience with a dumb noob like me. Did I learn from it? I don't want to exaggerate, but I feel myself a tiny bit smarter than two days before, that's at least something. Thank you.

[oshunluvr]

This should do it for you:

sudo apt install linux-modules-nvidia-390-5.19.0-46-generic

As it installs (do it in Konsole so you can see what happens) you should see messages related to DKMS module builds. When it's complete, type this in:

dkms status

and you should see something like:

nvidia-390, 5.15.0-97-generic, x86_64: installed
nvidia-390, 5.19.0-46-generic, x86_64: installed

[Schwarzer Kater]

So you should install the Nvidia driver again (it is missing for the 5.19 kernel) - if I am not mistaken the following should also install it for the 5.19 kernel even if you boot from the 5.15 one.

sudo ubuntu-drivers install nvidia:390
or - if ubuntu-drivers does not work - use:
sudo apt install --reinstall nvidia-driver-390

and reboot.

oshunluvr Thanks for your hint. This is what I get with the two commands:

$ dpkg -l |grep 5.15.0 |grep ii
ii iproute2 5.15.0-1ubuntu2
ii linux-generic 5.15.0.76.74
ii linux-headers-5.15.0-76 5.15.0-76.83

ii linux-modules-extra-5.19.0-46-generic 5.19.0-46.47~22.04.1​

Compared to 5.15 (the booting version) there are less elements in the (not booting) 5.19 package. OK, it might be a bit childish to simply count the number of files.

[oshunluvr]

Sound like you're possibly missing some additional packages for the 19 kernel. Try this:

dpkg -l |grep 5.15.0 |grep ii
dpkg -l |grep 5.19.0 |grep ii

Then compare the two lists to see if all extra stuff is there. On my system there's 4-5 related packages:

linux-headers-5.15.0-76
linux-headers-5.15.0-76-generic
linux-image-5.15.0-76-generic
linux-modules-5.15.0-76-generic
linux-modules-extra-5.15.0-76-generic

linux-headers-5.19.0-46-generic
linux-hwe-5.19-headers-5.19.0-46
linux-image-5.19.0-46-generic
linux-modules-5.19.0-46-generic
linux-modules-extra-5.19.0-46-generic

[ralfheinz]

Again: no luck – 5.15.0-76-generic boots, the rest doesn't

[Schwarzer Kater]

Then as a next step I would suggest to reinstall the kernel that is not properly bootable from GRUB:
sudo apt install --reinstall --install-recommends linux-generic-hwe-22.04
and try again.

[ralfheinz]

Schwarzer Kater You don't give up – brave!

sudo grub-install /dev/sda

I did that, resulting in no changes: Booting with 5.15.0-76-generic works, the two other ones remain stubborn.

[Schwarzer Kater]

A next step could be to rewrite the boot loader to your drive:
sudo grub-install /dev/sda
and try again.

[ralfheinz]

So you do get to your KDE Plasma DE?

Open the Konsole terminal emulator and enter: sudo update-grub to update your boot loader.
Reboot afterwards and try the different entries again, beginning with the "Ubuntu" one, then the submenu (not the recovery ones).

OK, thanks, I did the update-grub and tried the entries:

Ubuntu > no success
Advanced / Linux with 5.19.0-46-generic > no success
Advanced / Linux with 5.15.0-76-generic > successful, and yes I get KDE Plasma

The update-grub response:

All in all it seems to be a step back, as yesterday evening two of three options worked, while now only one is left. No problem, I'm happy that at least one option boots. Thanks again for your help.

[Schwarzer Kater]

OT: Thanks Clay.

Perhaps I am a bit "touchy" today, but why would you try to install parts of the *Ubuntu 18.04 LTS hwe in Kubuntu 22.04 LTS?

It is a compatibility meta-package in 22.04 (and 20.04), for upgrading from previous releases. It only depends on xserver-xorg, and nothing else.
The package used to be necessary when adding HWE support to 18.04, and previous LTS releases.

So you do get to your KDE Plasma DE?

Open the Konsole terminal emulator and enter: sudo update-grub to update your boot loader.
Reboot afterwards and try the different entries again, beginning with the "Ubuntu" one, then the submenu (not the recovery ones).

PS: And to answer your question - the first entry from the submenu should be linked to the "Ubuntu" one.

[Schwarzer Kater]

OK.
You have the generic kernels, that is a good thing.
Did you try both 5.19 and 5.15 from the GRUB menu (not the recovery ones)?

And how did you manage to enter the command when you don't get a login prompt or a tty?
Can you post a photo or describe exactly what you see when you boot from the GRUB menu (not the recovery entries)?
