Login Problem!

[vale461mito]

I can't access to my username in backbox!  :-[
I don't know why, but when i'm going to insert my password the screen is black with a lot of information just for one second then return to login screen!

I just tried with guest account but i can do nothing, i can't change nothing. I can't be super-user (sudo is not permitted).

Please help me!

Ps: sorry for my english!

Hi Rossi :D lol
Maybe try, while on the login screen, to do CTRL+ALT+F1 and try to log from there... in this way i think you will get some infos on screen. To switch back to login screen CTRL+ALT+F7.
If you get no useful infos, do you think you can grab some logs via external live system?
If you have long outputs please use some pastebin services online...

Good luck! ;)
