pls help me about this problem.


hi,
does anyone know how to fix this prob.
at first I'm working with my root terminal because it change from local host to -bash-3.2#, but thank god I already solve it.. but after that, I used to logout from my previous session, and when I come back in.. my username and password did not already recognize.. when i insert them, nothings happened.. I'm stock on log in menu. I try to insert other username and password but then it saids to be invalid, but when I'm inserting the real username and password, It's just like resetting all over again.

Need more specific details. You mean to tell me your PS1 environment variable was missing but got fixed?

If you deleted your home directory, you obviously cannot log in. NEVER RUN COMMANDS FROM AN UNTRUSTED SOURCE!!! If you see any commands you might think are dangerous to execute, please let me know. Here is a list of commands that can cause damage to your system. The command to delete your home directory (/home/<username>) is in there, if you accidentally ran it tough luck.

I am a bit confused about what problem you are experiencing.

You state that you had an issue with the PS1 prompt, but then state that you are unable to login with your user account.

Are you able to login as the root account?

If so, you can reset the password for your user account:
Code:
passwd username
entering your user name in place of username

Read what I posted about possibly (albeit accidentally) deleting your home directory. THIS WILL PREVENT YOU FROM LOGGING IN!!! Try booting from your Live CD and running the following commands:

Code:
sudo fdisk -l
sudo mount -t ext4 /dev/LOCALDISKDEV /mnt #while /dev/LOCALDISKDEV is the device file (typically /dev/sda1) that your Linux operating system is installed on.
ls /mnt/home
Post the output of ls /mnt/home here. If it reads empty, that means you accidentally deleted your home directory.

Yikes, that's pretty serious. Like I said, boot from the CD and try to fix it from there. Please note that /root is the name of root's home directory. So, please post the output of sudo fdisk -l run from the CD.
