Installed ubuntu on my work laptop, everything worked great and I was in love with it. Said laptop is no longer operational, so today I installed it on my second, older laptop - and it won't let me login. After putting in the password I get a black screen after a few seconds, queue the typical drum sound and I get the login screen again with no errors. Same happens if I try to get in as guest. I've tried entering a wrong password and it's immediately recognised as being the wrong one. I tried logging in through ctrl+alt+f1, and it accepted the password. Tried changing password through there, changing xauthority ownership, and ultimately deleting it (as following possible solitions I found searching here). Nothing. Tried a fresh install after that, no luck still. I'm out of ideas as of right now, and would apreciate some help.

Ubuntu version is 14.04 LTS, 64bit.

Toshiba Sattelite L650-1JT. 320gb hard drive memory, not sure on partition side since I didn't manually create any.
Graphic card ATI Mobility Radeon HD 5470

You did not provide any useful data to help. However, in 8 cases of 10 this error comes from X malfunction, and in 6 of 10 - video adapter drivers. What video card you use?
Anyway, try pressing Ctrl-Alt-F1 or F2 until you see a text login prompt. Log it. Then 

sudo -i
apt-get update
ubuntu-drivers autoinstall 
reboot
