[solved] Can't get past login screen after latest Kernel update

[lintek]

Today, after updating the system with the latest Kernel (5.4.0-135 ?) I can't get past the login screen. I type in my password and it simply goes back to the login screen. I am an amateur with Linux (even though I use it daily - just not a computer-guy per se'). I'm lost.

Maybe if I could revert the system to before the update?

Help!

Can you get into a terminal login by pressing CTRL ALT F1?

If you do this, you can uninstall the latest kernel by running the following commands:

Code: Select all

sudo apt remove linux-headers-5.15.0-56-generic

and:

Code: Select all

sudo apt remove linux-image-5.15.0-56-generic

Assuming your previous kernel is good, you should then be able to reboot into it.

IT WORKED! Thank you!

So how can I avoid this happening again if Linux wants to update?

IT WORKED! Thank you!

Launch Update Manager, click on Edit, Preferences, Automation and finally click on Automatic Maintenance. That will clear out any unused Kernels bar one.

THANK YOU again.

I would be lost without the members of this forum and I appreciate their help very much.

Why would removing the latest 5.15 kernel help you if you installed the 5.4 kernel? That does not make sense.

What version of Linux Mint are you running? And what is the output of uname -r?

If your system is too full, then you will repeatedly get the login screen even if you enter the correct password. Running Automatic Updates would prevent that from happening in the future.

Mint Cinnamon 20.3 - 5.2.7, 5.4.0-135-generic
This morning when I woke up the computer from being suspended, it was unable to open the desktop and said use CTRL-ALT-F1 to get to terminal, then use "cinnamon-unlock-desktop" to get desktop, then CTRL-ALT-F7 to get to the desktop.

"system too full"?

That means the commands S4qFBxkFFg gave you to run should have given you a message saying those packages are not installed and there was nothing to remove.

This morning when I woke up the computer from being suspended, it was unable to open the desktop and said use CTRL-ALT-F1 to get to terminal, then use "cinnamon-unlock-desktop" to get desktop, then CTRL-ALT-F7 to get to the desktop.

"system too full"?

The computer gave you a message telling you to use "CTRL-ALT-F1 to get to terminal" Or did you find that information on a post somewhere?

What is the current status of your system? Are you logged in or not?

I think that I got the message to USE AUTOREMOVE which I typed in, it did its' thing, and then I was able to log in.
(I am sorry that I am so bad at this...)

Yes, the computer popped up a window telling me to use CTRL-ALT-F1 to get to terminal, then use "cinnamon-unlock-desktop" to get desktop, then CTRL-ALT-F7 to get to the desktop.

That was enough to get you in, but you probably still have a problem and need to do some cleaning. Here are multiple ways you can reduce how much space is consumed on your install How to Clean Linux Mint Safely.

Thank you for the feedback. I was not aware the system would do that.

[lintek]

I decided to test it out, so I put the computer in SUSPEND. That I woke it up, (it even sounded like ti woke up), but I never got to the login screen. It just stayed blank. I had to reboot to login.

I rarely turn off my computer - I just use SUSPEND and wake it up the next morning. This is how I prefer to do it.

Any ideas?

Any ideas?

Yes, but we would need to see system information to know which ones might be appropriate.

Please open the System Reports app and click the System Information tab on the left. Your computer's information should come up in the right pane. Then click Copy, and paste the results into a reply window here so we can see how Linux Mint views your hardware.

Your computer has a 700 series Nvidia GPU. Starting with the Nvidia-470 driver, changes were made and many people have had problems resuming from sleep/suspend. The workaround mentioned in this post has worked for many people. If you need detailed instructions for editing the file then see this post and the subsequent ones in that topic.

Let us know if that resolves the suspend problem.

The "exit 0" trick worked.

Thanks - again.
