Failed to start the X server (your graphical interface). It is likely that it is not set up correctly. You will need to log in on a console and reconfigure the X server. Then restart GDM.
Ezin dut X zerbitzaria abiarazi (zure interfaze grafikoa). Agian ez da behar bezala konfiguratuta egongo. Kontsolaren saioan sartu eta X konfigurazio-programa berriro exekutatu beharko duzu. Ondoren, berrabiarazi GDM.
