Title: Stuck at Boot (SOLVED)
Post by: Rusty Acacia on September 13, 2020, 07:23:35 pm
I can't boot my Peppermint 9 installation, it gets past the splash screen and then gets stuck in what seems like an eternal black screen with a flashing underscore.

I had updated my system and installed steam before this but I don't know if that has anything to do with it.
I ran into a similar problem when I was running manjaro and I was messing around with the driver settings, a black screen with a flashing underscore that won't let me reach the login. Instead of fixing that I distrohopped instead and it seems to have found me again but I like this system so I want to keep it.

I'd appreciate any advice on how to fix this if this is repairable, if not I'll do another clean install.

Do you remember being asked to keep or replace a config file for the GRUB update?

Hey Rusty, welcome to Peppermint. There are two things I would highly recommend you learn how to do for the next time you run into a similar problem. First, learn how to use Timeshift and take a snapshot of your system when it is running good and especially before adding new software.  Second, learn how to use a DATA partition so in case you do have to reinstall from fresh you won't lose your personal files. Good luck.

I do remember seeing something about grub and choosing to replace something, or something like it might have been a pulseaudio prompt again.

Thanks for the welcome alynur, I did use a data partition this time but have not heard of timeshift before so I'll check it out sometime.

If you chose NOT to replace the GRUB file you might have trouble booting for that reason.

Is there any way to replace it now?

Actually I've just noticed you said you got past the PEPPERMINT splash screen so it's probably not the GRUB problem I was thinking about.

Good point, @murraymint.  ;)

So @Rusty Acacia have you tried to boot into a previous kernel or into "safe" mode?

Regards,

Different distros (Arch Linux & Lubuntu) - same problem - same machine. Interesting.

I'm wondering if this has to do with a kernel update, too  :-\

The specialized/quirky PM machine I'm on right now refuses to run properly on anything but 'Linux 4.15.0.23-generic'. I've tried unsuccessfully to update the kernel on this rig for a couple of  years, but it always ends up having hardware & display probs.

Does your machine boot up and run properly on a PM installation ISO stick?

If so, I'd suggest sticking with that kernel ver.

I have not tried a safe option as usually when it does boot it just goes from splash to login.

I have been using this forum just fine so far from the installation iso so I guess I've booted from a previous kernel?

Is there any way to revert back to the installation kernel?

You can give boot-repair a try.  It's a small lxde system that you put on a usb and has the ability to repair, not only Grub, but MBR in Windows, too.  I've used it a number of times when I couldn't figure things out.

I remember I had the same problem once when I disabled secure boot to enable proprietry drivers when installing Peppermint 9 Respin. When I rebooted after install was finished I got the same black screen with only flashing cursor. Installed it with secure boot enabled and when I rebooted I could log in.

That's weird Johan, it's usually the other way around.

I figured out how to enter the grub menu from the regular hard drive boot and I tried the recovery options, those booted just fine although both kernels in normal mode failed to boot. I tried modifying grub to change the kernel and found that maybe an update would fix that so I ran an update grub command but that didn't really do anything it seemed. Seeing how it was an update what might have broke the system and how I hadn't updated in a while I updated the system and what do you know a grub update, this time I did let the update replace the grub configuration.

It boots again, so thanks to everyone that gave suggestions. I really did not know where to start looking for the cause of the problem since I rarely run into problems with gnu/linux due to how stable it is.
