I have been using Ubuntu 14.04 with no problems for about 8 months now. I am looking to upgrade my processor, however, due to a few reasons. I wanted to test my graphics one last time before I bought my new processor, so I switched the driver under settings. When I rebooted, nothing works. I load my home screen, but I cannot use my mouse, cannot use any keys, nothing. Just an unresponsive computer. Does anyone have suggestions? I don't know what information is required but I'll provide what is needed once I know. The Graphics card is a MSI Radeon R260x

when you boot, select Advanced menu, Recovery mode and continue on to boot (effectively addingnomodeset
to your boot options)? You might be able to boot normally and remove the driver causing the issue. – bcbc Mar 03 '15 at 05:25
