After some automatic update of 14.04 that wose installed on my computer, ubuntu crash to enter in desktop user interface, and loop me at logon screen.
I decide to format hdd an install a fresh copy of 15.04. After instalation Same thing.
Reformat hdd, try to open livesession from CD or USB, livesession ask for username and password.
On other types of computers, livesession of the same USBs And CDs works great.
What can I do for debug?
