nvidia 290.10, monitor put in standby crashes X
With the nvidia 290.10 driver, when power management turns off just the monitor, then the system basically crashes. One is unable to wake the monitor. The system also stops responding to keystrokes. This does not happen if you put the entire system into standby using pm-suspend...in that case the system and monitor will properly wake.
This does not occur with the 285.05 driver.
I suspect this is a regression because this same behavior was occurring I believe about 2 years ago with an earlier driver....sorry not sure of the driver version or the exact time frame.
