I am new to Ubuntu. I installed Ubuntu 12.04 on my pc which is way old along with Windows XP. After installation I got a message "Run ubuntu in low graphics" I clicked yes and then I was asked for user name and password. But I keep getting the same screen over and over.
To summarize my ubuntu installation is hung at the login screen.
Try bringing your computer up in Recovery Mode, drop to the console and reset your password with the "passwd" command, then boot up normally. If you're running on an old system without too many resources you might try installing the Lubuntu variant, as it works better (faster) on systems like this.
Sounds to me that your user account doesnt have administrator access, known as ROOT. To do this you need to enable ROOT and that way you can run certain devices and installations.
With my first experience I installed ubuntu to a virtual pc rather than dual boot and played that way. I could surf the net on it and things were less risky, now with my knowledge and understanding i feel as if I can play and understand how to make this opperating system much more functional.
