Can't login to my account
I'm a complete newb, I am a student using school Linux system. My account was working fine. I was working on a file, and when I tried to save it, the message "unable to save the file" appeared. Then I noticed that I wasn't able to open any program on the system or create any files/folders. I logged out. Then when I tried to log in, I get this message:
"You session only lasted less than 10 seconds. If you have not logged out yourself, this could mean that there is some installation problem or that you may be out of diskspace. Try logging in with one of the failsafe sessions to see if you can fix this problem"
I know that I have plenty of diskspace. Can someone please help me??
Your help will be highly appreciated
Thank you in advance
