Cannot boot, Cannot login to recovery (where it says control-d)

hi,

I am pretty sure its not hardware related, as I can run a live iso, (and am posting now from it ) and can mount and view all drives and contents.

I am using ssd as sda boot. I have 175g free space on /

I have not performed updates recently, it has been booting normally for a the past few days. now it boots to a green screen with 3 square dots. I press escape to see the console.

I cannot login to where it says to enter root password, it locks up at that point, will not accept any keystrokes, tried ctrl-d and waiting a few minutes- nothing, rebooted and tried my root password, and waiting, nothing.

I found a guide to help troubleshoot boot issues but I cannot boot to the point of a console. (https://doc.opensuse.org/documentation/leap/startup/html/book.opensuse.startup/cha.trouble.html#sec.trouble.boot)

I really do not know where to start, any help is appreciated.

thanks

What you describe sounds like the plymouth screen.

At the grub prompt, hit ‘e’. That should put you into an edit mode.

Scroll down to the line beginning “linux” (or, maybe, “linuxefi”).
In that line, delete the “splash=silent” part. Then CTRL-X to continue booting.

That should boot without the plymouth splash screen. I don’t know if it will get you to the desktop, but it is worth trying. And maybe look at messages on screen during boot. The last few lines of message might be relevant to the problem.

Thank you for the help!
Oddly, it booted after that, though I can not think of a reason why…
Hopefully it continues I will know tomorrow. :confused:
Is there a way to save that config (without the boot quiet) so I can always see the boot process…?

Looks like it was doing a filesystem check maybe at last successful boot, just prior to shutdown?

last sucessful boot (end of log) (no logs fro last 3 partial boots)

You can also indicate that DE is used and also the login manager

If using the Proprietary Drivers
If it happened after an update etc.

Yes. Edit “/etc/default/grub” and look for GRUB_CMDLINE_LINUX_DEFAULT

After editing, run:


grub2-mkconfig -o /boot/grub2/grub.cfg

Sorry- my setup is all stock.
The only changes are multimedia codecs from packman.
Desktop: KDE
No proprietary drivers
no updates in last 3-4 boots (I am intentionally not updating as often),

hardware is amd64 8350/ on a asrock motherboard/ 16gb ram & r7-250 redeon video. 500gb samsung evo.for primary drive.

From the output I read that you have a btrfs file system. If things worked correctly before you should be able to boot a previous snapshot,

Appreciate the assistance - Thank you

Perhaps BTFRS maintenance/ balance kicked in to do some work. There is an issue on bugzilla that BTRFS maintenance renders your system unresponsive. I haven’t experienced it anymore in this extend, but had quite a similar issue in the past. The issue was/ is related to the snapshots.
