Looks like your screen resolution is too high for your monitor. Since you cannot simply run the system/administrator/monitors menu item, maybe you have an xorg.conf file that can be changed. You probably can log into ubuntu's virtual terminal -- type Crtl-Alt-F1 and see if you get a text login prompt. Login with your username/password and go to the directory /etc/X11
cd /etc/X11
Take a directory listing with ls
ls
If there is a file named xorg.conf, rename it to xorg.conf.sav
sudo mv xorg.conf xorg.conf.sav

Shutdown and reboot
sudo shutdown -r -t0 now

Hopefully, you will have a default, lower resolution, X working.
If not, we'll have to actually put the necessary into the xorg.conf file (or maybe edit it to see if you can just delete a high resolution mode line).

Take a look at the below link to boot into a text mode -- from there you can try modifying the xorg.conf file
