Cachy os unbootable

Issues & Assistance
1

I let my computer go to sleep. I come back to it not waking up. Restart takes me past the MSI cachy os screen with spinning wheel and gets me to a black screen with a dash mark in the top left that’s unresponsive. Full reinstall gives same results…is cachy broken ATM??

Try dropping to TTY or booting to runlevel 3 I guess?
Maybe at least we would see more in that case.

Fresh install here (installed 5 minutes ago) and I have the same issue. The bootloader (systemd-boot) pops up and then nothing.

I installed KDE and I’m running Nvidia 4090 - 9950X3D CPU.

Nvidia was a guess already. Please try one of the other methods above to gain further access or information.

I might suggest checking KMS and DRM-KMS. ex;

And further also checking, if in use, the backend of SDDM.
(If it is using wayland then try switching to X11 .. or bypassing the DM altogether)

Seems booting into gnome works for now? So it’s a KDE issue. I’m really unfamiliar with gnome haha but at least I have a PC.

Edit: yeah no…HDR doesn’t work right and other stuff ect not working the same in games. Not the same experience. Need KDE back.

got access to TTY, but I can’t start SDDM or KDE in either Xorg or Wayland. I get various versions of “Could not connect to display”.

I was able to install GDM and use that to start KDE.

The other thread has had some similar comments and movement..

(it would be nice if these could get merged …)

i think it is the problem with the kwin , which was not shipped with latest version by cachyos maintainer , but it was actually shippped in Arch repo

so that was the mishap happened
same for me

i just boot into the live usb and mounted all required volume(basically root one)
and chroot and after that i installed

sudo pacman -Syu extra/kwin

it will download the latest shipped/tested version of kwin directly from arch repo
it worked and for most of the people and will work for you also

This helped me. I dropped in TTY, installed kwin, and back to normal. Created an account just to say thanks!!

I confirm, I did the same thing, and it worked

  1. Boot from a LiveCD.
  2. Run lsblk to get information about all partitions.
  3. Identify the root partition and mount it with the command:
    mount /dev/{root_partition_name} /mnt
    (Replace {root_partition_name} with the appropriate partition, e.g., nvme0n1p2).
  4. sudo arch-chroot /mnt
  5. sudo pacman -Syu
  6. (If you encounter PGP key errors, initialize and update them as needed)
  7. Done

Mod please delete post. Thank you.

Without checking here I did a chroot from my alternate system as soon as I got home from work and did a pacman -Syu and kwin had already made into the cachyos repos and it fixed the issue. I would not have thought it was kwin based on the errors I was getting about AMDGPU but alas it was kwin.

It depends on what DE or WM you’re using. I am using CachyOS with Hyprland and I had to install sway-idle-inhibitor package for that issue.

Hi, I’m more or less a Linux switcher and player. So not that much experience yet, I hit English in the Google translator, I only had 1 year, so don’t hit. ^^
So I have the same black screen and wanted to follow the instructions, so far so good but with the command ‘arch-chroot /mnt’ I get the following line:

nvme1n1 259:3 0 1.9T 0 disk
├─nvme1n1p1 259:4 0 300M 0 part
└─nvme1n1p2 259:5 0 1.9T 0 part /mnt

[root@CachyOS liveuser]# arch-chroot /mnt
mount: /mnt/proc: mount point does not exist.
dmesg(1) may have more information after failed mount system call.
==> ERROR: failed to setup chroot /mnt

What is my error, because I can’t update the system with Pacman?

Mfg IROn

Hi, sorry for the late reply. I just saw it now. Try the version described by user ViperD21:

"
Follow these instructions to get into a TTY with systemd:

Linux CachyOS boot screen, hit the “E” key. This opens a text line, hit the end key to get to the very end of the line and add the # “3” to the end of the line past the word “splash” (make sure there is a space between the word spalsh and the #3). Hit enter to boot. This brings you into TTY. Log in and type update. After installing the latest updates (fixing kwin), reboot and you are back to normal.

While this is already covered in the first response/link .. since it is typed out again here I will also mention that to reboot one could enter the following command in TTY:

systemctl reboot

HI, I managed to do it today, my system works again.
Bach search I found a Tutorial and it worked well. Out of there I did the following:

sudo -s
pacman -Sy cachy-chroot
cachy-chroot
pacman -Syu

Then restart and the desktop came back.
