Can't login into my elementary

I'm not able to access my OS anymore, when I want to login the login screen disappears for a few seconds, so I only see the background image, then my screen turns black and I'm at the login screen again.
I tried to do that chown Xauthority but that didn't change anything

 

any chance you have a nvidia card?

 

Yes I have a nvidia card

 

You may can login in text mode with CRTL + ALT + F1, this way it is possible to check the logfiles what happens while your login fails. (back to graphic mode is CRTL+ALT+F1)

Unfortunately this requires a little bit advanced knowledge, how to check several logfiles what happens in text/terminal mode.

Maybe you can first upgrade your distro with the commands sudo apt-get update && sudo apt-get upgrade to check if its better afte a reboot already?

 

Also my screen is now fully black I can't do anything, I'm only able to access the terminal over ctrl + alt + f1

I could fix it now but I dont know what it fixed. The commands that I typed were :

Sudo dpkg --configure -a
sudo apt-get purge nvidia*
sudo apt-get install --reinstall xserver-xorg
sudo apt-get update
sudo apt-get upgrade

 

To get back to the login screen do CTRL+ALT+F7. I had the same problem, so this is the best I can do. I’ve even tried a reinstall of the distribution with sudo apt-get dist-upgrade to no avail. I can’t tell if I have an nvidia card. Please help.

Hello I'm a new user for Elementary OS. About the error that make you can't login into it. I had some advice maybe can be useful. The first I Installed this,

1. I activate automatically login when I'm installing the Elementary OS.
   
   
2. The second thing that I did,I had removed the apps that I didn't need,Idk it has a relationship with the data login that can cause and error or not. The only app that I removed is calculator and I don't anything expect that. Well beacuse I was too afraid about the error that hard to find out about it
   
   
3. I test with sudo apt-get update,even I try sudo apt-get upgrade,I do it twice
   
   
4. Even I install wifi driver that do update and upgrade
   
   
5. I have seen the error like firmware ,but now i didn't see it anymore,idk why
   
   
6. Oh right,don't remove the feedback
   

And now even after I suspend or in lock mode,I can unlock it. I felt depressed aboout this,I hope my advice can help you. I curious about why the developer doesn't tell us how to fix it. Or why he didn't have an old version before 5.1.

Hi Nura. Sorry to hear about your issue.

Can you clarify, that the login is ok, but it's only when you suspend or lock your laptop that it goes blank?
Also what video card do you have?

 

I can't tell you what video card that I had but..maybe I could tell you that I'm using Laptop Lenovo Ideapad 130-14AST. After the os installation,I'm just using it and doesn't install anything except the wifi driver.

 

The login is okay,
I have tried reboot and after I pressed lock my laptop,I still can unlock it,even I tried ctrl+alt+prtSc ins + R+E+I+S+U+B

I still can lock ,and unlock my laptop

 

Oh forgot to tell you,I got an upgrade on App Center precisely in OS upgrade,but don't know what it is,so I just upgrade and reboot,and do the same thing lock and unlock,it still doing okay

 

I'm sorry, i'm not finding much for the Lenova laptop you mention. however there's a few simple commands we can use to find out more about your hardware and what might be causing the problem.

Firstly, lets list out both the USB and PCI hardware you have. To do this run the following two commands:

Code (Text):

sudo lsusb

This will list out all the USB devices connected to your laptop (some internal hardware embedded in the laptop sometimes also show as usb). Please copy the output and paste it in your reply.

Code (Text):

sudo lspci

This will list out all the PCI devices connected. Please copy the output and post it here.

From these two lists we should be able to see what graphics cards and wifi cards you're having, one of them maybe causing the problem.

Also if you can attach the Xwindows log file (found in /var/log/Xorg.0.log) that should tell us if you're having any errors with the xwindows system.

Hope with this info we can help you.

 

Sorry for late,it's AMD

 

Thanks, can you try running the two commands in my post above? lsusb and lspci. That should tell us the exact make and model of your AMD card.

Also if you can post your /var/log/Xorg.0.log too, that should tell us which driver your using on your AMD card, that way we can track if that particular card has any compatibility issues.
