[SOLVED] cant boot

[dusty rock]

arch is working fine 3 hours ago until i booted up the computer now here is what i observed

• screen goes on and off at the bootloader when i plug video into video card, its in a loop
• plug video into mobo and its a blinking cursor
• lts and fallback doesnt solve the issue
• cant switch tty
• services seem to be working as i can read the cpu usage and temperature off my cpu cooler

the last thing i did when it was working was run my own python scripts and play osu with wine

this is my live os rn its kind of annoying, this shouldnt be happening

mounted home and root directory successfully

last things i saw

[balmy wedge]

What gpu do u have?

[dusty rock]

nvidia

[balmy wedge]

are u using nvidia propietary drivers?

are u using a display manager to launch some de?

[dusty rock]

i think so?

https://github.com/korvahannu/arch-nvidia-drivers-installation-guide

i followed this

[dusty rock]

i honestly dont even know what display managers are

until i just googled now

[dusty rock]

just a guess but

Option B) For systemd-boot users
Navigate to the bootloader entries directory: cd /boot/loader/entries/
Edit the appropriate .conf file for your Arch Linux boot entry
sudo nano <filename>.conf
Append nvidia-drm.modeset=1 to the options line

i did this for all my bootloader entries

if nvidia is the issue then how do i reverse this

where do i find the entries

[balmy wedge]

did u use archinstall?

[dusty rock]

yes

2 months ago

[balmy wedge]

oh god

did u select some kind of graphic environment

such as plasma, gnome, etc

[dusty rock]

xfce

[balmy wedge]

Alright so

Get into a tty please

And exec: systemctl --type=service

[dusty rock]

wish i could but ctrl alt f3-f7 isnt working

[balmy wedge]

about the nvidia drm option, it is not neccesary at all, u can try removing it to see if it works

apart from that, i am thinking that some displaymanager is causing the issue

can u try doing this: sudo pacman -Q | grep sddm

[dusty rock]

i cant get a terminal

or do i chroot from live iso, will that work?

[balmy wedge]

Yes

[dusty rock]

all these audit messages are driving me nuts

[dusty rock]

im an idiot i didnt mount the efi partition

ok i am able to get a tty now but its only on lts

the only failed here

guess i never knew what dm i used

now i know

wait now that i think about it i might have done something that broke this

lightdm rings a bell

[balmy wedge]

ok i guessed it was sddm but it was lightdm

no problem

so u probably have that black screen caused by lightdm failing

try to disable it for now, then enter xfce manually with xinit and then we will try to solve the issue if wanted

[dusty rock]

this was a stupid action

1 thing needed imagemagick and i think it might be lightdm

or am i tripping

it was working for 3 days after

[dusty rock]

ok what after xinit

disabled lightdm with systemctl

GOD BLESS

this has been the worst 26 hours of my life

kept worrying about my precious computer at work today

[SOLVED] cant boot

[balmy wedge]

So if u disable it u can at least start ur xfce

Then solve ur issue in a more comfortable way

Great u solved ur issue

Have a great day

[dusty rock]

it wasnt anything to do with this

[dusty rock]

just looked for similar users who encountered this

[dusty rock]

this was their fix and it worked for me after enabling and restarting

[balmy wedge]

Ik but its better to disable it

To fix the issue in a better way
