Anyway, to get over it do ctrl-alt-F1 to get a console and type "sudo adduser trisquel". Then alt-F7 or alt-F6 to get back to login screen. Now the login should be succesful.
"sudo restart gdm" might also work.
It seems you have encountered the same bug I once got. For some reason there
is no default trisquel user. Did you use older beta image?
