[SOLVED] Latest kernel versions don't have graphics.

[tumbledryDishwasher]

Hi! I've been using Siduction for the past few months, and it's been very nice as my first ever distrohop (I was using Mint before).

I've had a problem where Kernels 6.15.7-1-siduction-amd64 and 6.15.6-1-siduction-amd64 both fail to load to sddm. They both reach chkrootkit on the loading terminal screen before getting stuck there. I can use Ctrl+Alt+F2 to reach a terminal view and login through that, but visuals never appear.

6.15.5-1 does work just fine, though. From reading the other topics around here, it may have something to do with NVidia's drivers? I wouldn't know what to do with that information, though.

Basically, I wanted to ask for an explanation / a way to fix it, since going through the [DE] thread with DeepL could only get me so far (yeehaw american English and all that). I'm not too deep into general Linux knowledge, but I know my way around the terminal.

(If this is the wrong spot to put this thread, my apologies. First post and all.)

Appreciate it!

It begins DE and moves to EN ...

Ah, yeah. Suppose that would be a necessary step.

I had scrolled through that post before, like mentioned. Checked again, still confused. I know it's a problem with the Linux Nvidia Drivers, and I know they need to be patched, I guess? Either that or updated.

Either way, thanks for your help.

Do you have the sidution fixes repo enabled?

Look at

apt policy nvidia driver whether or not you have the unfixed Debian version or the fixed siduction version of the driver.

I assume they *look* the same in inxi!

Sorry for the delay, I got sick at the worst possible time.

Update: it has gotten worse and I can no longer get to the boot screen at all. I still have the terminal, sure, but without graphics, it basically makes my PC for the tasks I use it for completely useless.

The nvidia persistence service fails to start, and I've tried a few things, notably reinstalling the nvidia-driver package and trying different kernels... Essentially, basic troubleshooting steps. I'm at a complete loss on what to do anymore.

[michaa7]

did you

apt update && apt dist-upgrade ?

In /etc/default/grub you need a line similar to this:

GRUB_CMDLINE_LINUX_DEFAULT="quiet systemd.show_status=1 nvidia_drm.modeset=1"

Hi again! Okay, so firstly, yes I did do a full upgrade sweep to try and get it fixed, with no dice.

I didn't see the grub thing until much later, but it turns out that it's unnecessary (sorry).

So after a bunch of troubleshooting with apt, looking stuff up on my phone about how drivers work, I managed to stumble across the solution of "Install the headers, you goof!". I think what happened was with an apt autoremove, it removed some of the headers for versions I wasn't using at the time. Get a kernel update with an upgrade, remove those same kernel's headers with an autoremove, go up one, the headers are gone, so no drivers. try to update and autoremove again from the terminal (ctrl + alt + f2), therefore removing the other kernel's headers.

Basic TL;DR: I did

Code Select Expand

sudo apt install linux-headers-6.15.7-1-siduction-amd64
then rebooted, and everything is good again.

Real weird, but now I know for the future.
Sorry for the trouble !

[towo]

Don't install linux-headers-$version-siduction-amd64, install linux-headers-siduction-amd64

[tumbledryDishwasher]

Thanks for the advice! I did that, it installed the newer ones no problem.
