I have used Ubuntu for almost a year now, but recently I have been forced to use my windows partition because

  1. I can't connect to the internet. I can see a list of available wireless routers but I cannot connect to one when I click on it. So, no internet.
  2. My user is the administrator but I can't change anything in the settings.
  3. I cannot change users, restart or turn off the computer.

I was thinking that if I upgrade to Ubuntu 12.04 it will work again. But without internet that won't work. :(

Would you please open a terminal window and run the command groups MY-USERNAME where MY-USERNAME is replaced by the username which you are having problems with? Add the output to your question. Can you still use sudo? Could you provide any further information about your wi-fi problem? Are there any error messages in /var/log/syslog? –  irrational John May 15 '12 at 13:58
    
Download Ubuntu 12.04 from Windows. Install it. Don't do whatever you did that caused whatever issues you're having. That will fix your issue since you won't "have to use [your] windows partition now". –  user55822 May 15 '12 at 14:37

For problem 3 above

I assume you upgraded to 12.04 and now can't login properly. I had this problem too. There are two fixes that I've seen:

  1. rm .Xauthority

  2. use terminal to type "ls -l /home"

If your home folder is now owned by a user with a number (e.g. "1016" instead of "suffah"),

Using "sudo chown yourusername:yourusername /home/yourusername" might do the trick.

also, you can use the "adduser newuser -u 100X" to create a new general user called "newuser" on your system (with 100X being the user id listed as the owner in the "ls" command)
