virtualbox.org

I have install ununtu linux on virtualbox. When I try to login by user as I was registered, the system is reading password and show the same window again. If I input a wrong password, the system write that the password is wrong, but if i logging by guest session the OS is loading and gui is starting. it`s problem which is stipulated by virtualbox or it`s problem of linux?

It is a problem with the guest OS, Linux. One common problem is not configuring the keyboard layout correctly.

So and what i can do? Install other OS, for example SuSe or other?

There is no point in repeating the problem with a different guest OS. I would ask on an Ubuntu forum about how to reconfigure the keyboard layout to match your keyboard. And/or describe your login problem there.

thanks, try to use other
