I was using Ubuntu 13.04 alpha and I usually install new updates after I completely upgraded to stable version on 26th it's only booting to terminal prompt,
startx on terminal prompt and then only desktop appeared after that I accessed terminal by short cut and prompted
unity and enter and unity appeared and full system running.
I want to run system properly without going through messy process please help.
N.B: Previously it showed
couldn't initialize agpgart module error was displayed in recovery console.
