Default key problem slimkat

hi, i'm on slimkat 4.0 and in my usb keyboard's esc key doesn't work like back (keytest recognize it n111) and home buttone is not recognized by keytest and it doesn't work, on cm11 and beanstalk the keyboard's esc(back) and home(home) keys worked perfectly i've tried it some minutes ago, i've tried on slimkat to edit system/usr/keylayout generic qwerty and all keyboard models and set key 111 to go back, but after reboot nothing changes, there is a way to map they? or any fix for this issue?
