Something is broken with LM.. All kernels are left, when you remove them tools and headers stay.. Also if you r move 6.8.. It marks for removal all kernels..

It was around €70, I can write off the cleaning so it's not that big a deal. I'm a clumsy one so I'd be a little nervous about cracking it open myself. As for crashes, I have run some heavy renders in DAZ and no troubles. Thanks so much for your help!

Ha, did it fix your crashes? How much was it? Its usually not too hard to clean, see if there is a YouTube teardown for your laptop.

I went and had my Laptop professionally cleaned, and the tech said he pulled out a whole cat. I have now budgeted regular cleans into my work expenses.

Thats seems fine, but I'm no expert on smart, I would do a clean out. Cat hair is the worst.

Yeah it does get quite hot and I live in a dry dusty climate with cats, A cleaning is something I think it needs regardless. I actually got the suggestion elsewhere for disk health and using smartctl I got this but I had just turned it on to perform the test:

Seems young for the SSD to die, but next time its on, check the disk health.

And if it tends to get hot, definitely look into cleaning the vents and fans.

About 3 years old.

Oh, thats very strange then. I'm still kinda leaning toward hardware being the issue, is it an old laptop?

Purple screen was during a file transfer, I wasn't in the room.

Open /etc/default/grub in the editor of your choice, GUI is fine.

Look for the line that starts with GRUB_CMDLINE_LINUX="...", and add the suggested change to the end of that line, but within the quotes. Save

Then in a terminal, sudo update-grub.

Ok, attempted to kill init is a different kind of panic, your drivers are probably fine. Did you get that as it booted up? You turned it on, and it quickly dropped you into a shell, and you pressed ctrl-c/d at that shell, and got the panic?

I'm suspecting some kind of hardware issue tbh, either SSD failing (failing during copy), or maybe GPU overheating? Overheating is the easiest to fix if you are comfortable opening the laptop, cleaning the fans (don't compressed air it, that can kill fans, toothbrush and paper towel is safest) and heat sinks, and then redoing the thermal paste.

If you can boot it up, run the smart tests on the SSD to try rule that out.

Only because I had ALOT of trouble editing fstab recently, I want to confirm if I am using the GUI instead of terminal that I right click the grub file, open as root, and add the line at the end and save correct? And then I assume I reboot, or is there a terminal command that refreshes? Just want to be clear as I get nervous with this kind of thing.

The only thing I was doing previously was trying to set up a jellyfin server at the time (storage is on an external HD) I have moved Jellyfin to another laptop. I have had Mint installed for most of the year and it has been excellent with a few tiny bluetooth issues that I just live with.

This was the screen when the troubles started.

I have only gotten this screen the one time. While I was desperately trying to get a back up saved, the laptop kept shutting down during the heavy data transfer with a black screen and this message:

[ 6.169528] amdgpu 0000:05:00.0: [drn] ERROR dc_dmub_srv_log_diagnostic_dat a: DMCUB error - collecting diagnostic data_`

I ended up having to reboot with the power button, and finally got a backup.tar sorted out, and actually have been using it lightly, but I will have to be using it for some graphics heavy work in the coming week, so I was hoping to get into some fixin' before then.

Thanks for having a look.

ACPI errors are completely normal, most motherboards don't expose all the information Linux wants, just ignore them. Never seen the DMCUB error though, but as other users have said, that's not the kernel panic, just a (likely) unrelated error message that may or may not be significant. From a quick search, the error is a bug in recent kernels related to AMD GPUs, see e.g. https://www.reddit.com/r/archlinux/comments/1wetjg6/amdgpu_dmcub_error_fixed/

Edit: https://community.frame.work/t/system-gets-really-slow/61854/2 Try adding amdgpu.dcdebugmask=0x10 to the kernel boot parameters in /etc/default/grub

Triple backticks to get a code block, makes it a bit easier to read.

Are you getting an actual kernel panic, or just this error in the logs? Error is probably no big deal unless you are getting a panic/crash. Take a photo of the kernel panic screen if you can.

Have you been trying to install a driver or something like that? Or is this a fresh install?

Debian and Mint likes to use stablty over cutting edge software and the update app is just a frontend to apt even updating from terminal gives same packages

You'll eventually get notifications telling you you're running out of disk space on that partition and the solution is to delete all your old and not utilized kernels. Just delete them now and every once in a while that you remember to

If you aren't booting that kernel it doesn't really matter either way as far as I know. If you aren't using them they will just take up space anyway, I could see having one or two for backup but fwiw the default on Arch is to only have the current kernel unless you install extras. If you haven't noticed any major glitches in a week or so I would think it's pretty safe to prune the old kernels.

No real reason to keep them, if you've already been able to boot into a newer one and haven't had problems with it that might necessitate going back to an older one. But at the point you can remove them, you can also reinstall them if that comes up.

They shouldn't cause any problems or vulnerabilities if they aren't what your system is running, but I removed them anyway

Thank you

the flatpak version is generally more up to date in my experience. but you can also sometimes go directly to a software's website and find their packages, which is also more up to date. Like Audacity for example has a new version out that isn't in the mimt manager yet.

I stick with the package manager for most things out of convenience, but I install the latest version of Blender, GIMP, and Jellyfin manually because I use them a lot and the feature upgrades can be significant.

If you're five, I'm six, so I can't help more than that.

Thank you for the information

1. Does the package Manager just run the most stable version of Libre office?

more or less, debian and by extension mint prioritize stability over the newest stuff, so the new versions are added later than bleeding edge distros after some of the quirks are ironed out, of course distro agnostic package managers like flatpak do not follow this rule so they tend to have the newest versions available

2. Is there a better way to update my programs using the package ? Even if it’s a terminal window command?

The software center is just the frontend for the terminal package managers so updating with either one will get you the same results. If you want something more up to date you can try installing with flatpak, or other package distribution ways like appimage. Either way in my experience unless you're running bleeding edge hardware or similar, there doesn't tend to be too much you're missing out on
