I recently upgraded my Ubuntu 12.04 to 12.1. When I rebooted into Ubuntu the monitor completely lost sync, so I had to shut the pc down. I made an installation DVD and tried to boot from it and possibly reinstall, but the same thing happened with the monitor. I had no problem with 12.04 and previous Ubuntu versions. My monitor is an older Viewsonic VPA150. In Windows 7 my monitor driver is "generic non-pnp". Any ideas how I can change the driver and be able to see what is going on??
