Hullo,
Maybe these 2 are places to start:

[HowTo] Resolve an unbootable Manjaro (black screen, login failed, cant boot, etc)

When we have problems gaining access to our systems it is difficult to gather information, let alone fix any problems. Here we will cover common causes and solutions to ‘manjaro wont boot’. TTY If your desktop does not load properly then you might still be able to use most, if not all, functionality by dropping to a non-graphical TTY. By default your system will have multiple TTYs, with each corresponding to an Fx key. Your desktop is assigned to one as well - most often F1. You can chang…

[HowTo] Provide System Information

This tutorial is superseded by this one. Remember all Tutorials are wiki posts that can be edited by TL2 (Trust Level 2) members and above. Welcome to Manjaro! To allow all of us helpful people on this forum TO HELP YOU, we need some basic information about your system. This probably means you described the symptoms of your problem, but now we need some more information to know where the origin of your issue is exactly. Someone else probably linked you to…

Oh and maybe this:

[HowTo] use public command-line pastebin services without installing anything!

Sometimes we might want to easily share terminal output. While this can be accomplished directly in the forums or manually through websites like pastebin, there also exist a number of open services that allow you to paste and share directly from the command line by using tools you already have installed. This is great for many situations, including troubleshooting from a non-graphical boot, or simply very large outputs. Here I will share a few examples and how to use them. Services and Exampl…

Ah I will try to gather more information and I will respond later cuz I can’t post photos

[ydar]

What sort of photos do you plan on sharing, I ask because they may be useless for this topic, and ultimately removed by a moderator anyway. We don’t need to see black screens or screenshots of text either.

[Xedoes]

You installed vesa for some reason. That will likely break things.

sudo mhwd -r pci video-vesa
sudo mhwd -f -i pci video-linux

Edit. fixed to add pci

[Xedoes]

got error for this commands invalid use of option -i/–install and it only display after that help

[Mirdarthos]

It should be:

sudo mhwd -f -i pci video-linux

[cscs]

Oops, sorry, I forgot pci

sudo mhwd -r pci video-vesa
sudo mhwd -f -i pci video-linux

[Xedoes]

okay now it did a thing removed vesa and installed video linux shloud i try run sddm?

[cscs]

Give it a

systemctl reboot

[Xedoes]

OMG it worked!!! thank you very much u really saved my rig from reinstalling system damn now im glad anyway that i switched from other os btw any advice for future?

[cscs]

Glad it worked out.

@Xedoes

any advice for future?

Just dont install vesa

PS… to explain a bit about vesa … its supposed to be ‘generic’ … but really … it just doesnt work at all on a lot of devices. Heres a snipit from the man page:

vesa is an Xorg driver for generic VESA video cards. It can drive most VESA-compatible video cards, but only makes use of the basic standard VESA core that is common to these cards. The driver supports depths 8, 15 16 and 24.

ooooh okay noted!
