But you could login (without seeing it), right?  Or it was completely frozen?
If it's only about graphics, you could do the normal reboot (e.g. via
ctrl-alt-del) and get the previous boot log, or typing blindly to login and get
dmesg output to a file, then reboot.

Also, please give the full contents of dmesg output, not truncated one.
