I've got a problem with Ubuntu 13.10. I installed the drivers for my ATI Mobility Radeon HD 3470. The installation was just fine. When I later on was doing a reboot and logged in it just returned to login screen. I put in my password and pressing the enter key. The screen went black and a second or to later I was back at the login screen.
I'm posting a link to a Youtube video showing the problem.
Ubuntu 13.10 runs on a Toshiba Satellite A300D. Before I was installing the driver the login went just fine. The driver I was using is AMD Catalyst™ 13.1 Proprietary Linux x86 Display Driver downloaded from here: http://support.amd.com/en-us/download/desktop/legacy?product=Legacy2&os=Linux%20x86
I hope someone can help me to solve this problem.
Thanks in advance.
