It seems that the X or Wayland server is not starting because something is wrong with a graphics driver. gdm will try to start it several times before giving up. This can cause the blinking that you see. Try switching to another VT (e.g. press Alt-F2). You should get a text login prompt that you can use to start a shell. You should be able to find some information about what went wrong with this command: sudo grep gdm /var/log/messages I hope you can work out how to copy that text into a file and then an email; if not then ask about this on debian-user.

[...] You need to log in (as explained above), enable non-free packages (see https://wiki.debian.org/SourcesList), and install the firmware-amd- graphics package. Then you should probably reboot. Alternately, reinstall using an installer built with non-free firmware included: http://cdimage.debian.org/cdimage/unofficial/non-free/cd-including-firmware/ Ben. -- Ben Hutchings Any sufficiently advanced bug is indistinguishable from a feature.
