Hi I just want to file a bug report to nvidia and following this post

It ask me to run startx -- -logverbose 6, I did so and the screen freezed…

I then reboot my computer and popped up the login screen.

But after I typed in the password, it went black and return to the login screen.

It loops infinitly and I cannot login…

Hi @Shore,

Obviously something happened. Where I don’t know. But I suspect we can check the logs and find out why it’s not working. To do so, enter a chroot environment and from there inspect the logs:

How to chroot

  1. Ensure you’ve got a relatively new ISO or at least one with a still supported LTS kernel.

  2. Write/copy/dd the ISO to a USB thumb drive.

  3. When done, boot with the above mentioned USB thumb drive into the live environment.

  4. Once booted, open a terminal and enter the following command to enter the chroot environment:

manjaro-chroot -a
  1. If you have more than one Linux installation, select the correct one to use from the list provided.

When done, you should now be in the chroot environment.

But, be careful, as you’re now in an actual root environment on your computer, so any changes you make will persist after a restart.

Once successfully logged into the ch root environment, we need to find the logs. To do so, follow below inside the chroot environment:

Finding errors for boot

journalctl --priority=warning..err --no-pager --boot=-1

Where:

  • The --priority=warning..err argument limits the output to warnings and errors only;
  • and the --no-pager formats the output nicely for use here, on the forum;
  • the --boot=-1 argument limits the output to log messages from the previous boot. This can be adjusted to -2 for the boot before that, -3 to the boot before that, and so on and so forth.

Feel free to provide the logs if you cannot find the problem.

Hi thanks for the quick reply

I just found a post that let me login…

Well I simply deleted ~/.Xauthority and reboot

BTW, I’m on my work now.

I will try to re-produce the issue when I have time and upload the log~~~
