Problem Description:
This post is hidden. You deleted this post 18 mins ago.

I am using a working Ubuntu 24.04.4 LTS dual boot with Windows 11. Both are independent, on their own M2 with a choice from Grub.

When I boot it now fails, leaving me at the ‘-’. I have to use CTRL/ALT/DEL to get to the kernel options.

The options I have are:

  1. 6.17.0-1012-oem

  2. 6.17.0-1012-oem (recovery)

  3. 6.17.0.19-generic

  4. 6.17.0.19-generic (recovery)

If I choose 6.17.0-1012-oem it fails as above. I choose 6.17.0.19-generic and it boots and works correctly but fails again on reboot.

The install is very recent but the panel was on the wrong monitor and it would disappear, only returning if I clicked on the screen. The computer appears a little slow too.

I found help for the panel but didn’t note the web page. It suggested a different kernel, again I didn’t note but it should be (1) 6.17.0-1012-oem which is default at the moment.

Can anyone assist please?

You might consider removing that, as it seems unintentional.

Q: Why do you have an oem kernel installed?

You seem to have a Linux kernel that is not loading to a login screen. You should be seeing a Grub boot menu. Select Advanced options for Ubuntu and select either a Linux kernel with recovery mode and at the recovery menu select Resume.

Or select an earlier kernel. The 16.17.0.19-generic. It seems that the OEM kernel is the default kernel and it is failing to load fully.

Regards.

As the default 6.17.0-19 kernel apparently works for you I also wonder why you have installed that oem kernel version 6.17.0-1012 which is not one that comes from normal updates unless you specifically chose to install it.

Do you need it to overcome some other problem we are not aware of?
If not just remove it and continue to use the default kernel series.

Sorry, but if I knew how I would remove it.

I really don’‘t know why I have an oem kernel installed, nor how to revert to the default kernel for this OS.

The default 6.17.0-19 kernel works for me in as much I can log in but as I said, every time I log out it reverts to 6.17.0-1012, It must be the kernel I installed to correct the panel problem I had immediately after installing the OS recently.

7

I tried your suggestion to select Resume but never got a resume option. Instead I had a list of options to choose from.

Your suggesttion to select an earlier version kernel is good thank you, but how do I do that please?

8

If you wish to remove the troublesome kernel, boot into kernel 6.17.0-19, open a terminal and enter

sudo apt remove *6.17.0-1012*

The asterisks are important, the command will find all the dependent kernel packages

9

Might also need to check dpkg -l|grep linux-oem and remove if it is installed

Thank you.

I did that and now it rebooted.

makem@makem:~$ sudo uname -r
[sudo] password for makem:
6.17.0-19-generic
makem@makem:~$

Marked as solved.
