Repeated Flickering

[Anuraag Aithal]

I recently installed Ubuntu 14.10x64 in my computer, and the 346.22 driver for my GT 610. After that, the screen is repeatedly flickering in Firefox. I tried reinstalling the driver, but when I shut down the X-server - "sudo lightdm stop" the desktop GUI reappears. Being a very unexperienced user of Ubuntu, its hard for me to explain exactly wat's happening. The driver is not coming in the startup too. I followed the steps mentioned in ubuntu forums for uninstalling, but it mentions that the driver is not installed.
