I have installed Ubuntu with wubi, dual booting with Windows XP. The installation is completed and the boot to Ubuntu is successful to the login screen. However, when I input the password, it takes me to a blank screen with only the wallpaper displayed. There is no menu, no left click menu either; there is nothing can be done at this stage. The only way to leave is through Ctrl + Alt + Delete.
The boot to WinXP can be done as normal.
Please help advise what is the problem and how to solve?
