My laptop is stuck on boot

I'm using Ubuntu 22.04 with the KDE Plasma DE (I can't remember what version I'm on, but it should be 5.something). I seem to have updated Linux itself to the latest version from Discover then rebooted my laptop when prompted to and it hasn't proceeded past this for a full day now. Here's the message currently on my screen.

Is there a keybord combination I need to press to fix this or am I going to have to reinstall Ubuntu from scratch. I really don't want to have to go back to Windows as I've been enjoying Ubuntu so far.

Ubuntu boots just fine when I go through "Recovery mode" and "Resume".

What is the GPU? What do you man by "the latest version of Linux"?

Nvidia K2000M, and by the latest version of Linux, I mean just that. The file size was over 100mb, and I believe it was called linux kernel or something like that

It would help me if you're specific with details; Ubuntu 22.04 LTS with KDE, so this was a Ubuntu Desktop install on which you added `kubuntu-desktop` or something else? or you installed Kubuntu 22.04 LTS? Did you upgrade the KDE using backports? if so which one... If you're specific with details, we can better understand what *software stack* you're using & thus what are likely the best recovery options... Ubuntu *jammy* with HWE recently switched from 5.15 kernel to 5.19 so I wonder if that's at play; if it is selecting an older 5.15 kernel at grub should still boot..

As there are different default to an install if you used Ubuntu 22.04 LTS or Kubuntu 22.04 LTS media; being specific lets us better understand (*with differences with 22.04(.1) & 22.04.2 media for Kubuntu too*) so we're somewhat limited in what we can suggest given lack of details as to your stack. If you're using Kubuntu I have no objection with you calling it Ubuntu (*I do myself! as it is to me*) but its helpful if you're specific. [Official flavors like Kubuntu](https://ubuntu.com/download/flavours) are on-topic here.

I installed Ubuntu 22.04 then installed the KDE Plasma Desktop Environment. If there's any more info I can give about my install, ask away.

What packages you installed with adding the KDE Plasma desktop are useful... I'm a *lover* of multiple DE installs on my systems, and would normally add `kubuntu-desktop` to get everything, but if you install it using other small *meta* or other packages; the results differ based on release, so please be specific with details. If your install was Ubuntu 22.04 Desktop media then you're using the HWE kernel (*as per my prior comment on that*) so try older 5.15 at grub as suggested.

I picked the option that installs everything KDE. How do I change the grub version? Entering "Advanced Options For Ubuntu" reveals 4 options 5.19, 5.19 recovery, 5.15 and 5.15 recovery. 5.15 works as normal so how do I get Ubuntu to start with that by default rather than 5.19?

installs everything? To me that implies `kubuntu-desktop` as that contains all of KDE & everything Kubuntu prepared for use in Ubuntu. If you use something else you should specially say. 5.15 is the GA kernel stack for Ubuntu 22.04 LTS & the default if installed with Ubuntu 22.04 LTS Server, Kubuntu 22.04/22.04.1 media.. but not Ubuntu Desktop 22.04 LTS media which defaults to HWE (as does Kubuntu 22.04.2) . Refer https://wiki.ubuntu.com/Kernel/LTSEnablementStack for details on GA/HWE kernel stack; both stacks can co-exist except if some nvidia etc. kernel modules are used

In that case, yeah I used `kubuntu-desktop`. The link doesn't give me info on how to boot with 5.15 instead of the latest one

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.
