display flashes on and off repeatedly every few minutes
I'm running a Latitude E4300 with the Intel 4500HD integrated graphics. Lately, the display has started to flash on and off several times an hour. Usually all I have to do is move the mouse or hit a key, and the display comes back (the back light is on when this happens).
Once and awhile, my monitor goes into standby when this happens, but if I turn the LCD (a Dell 2007FP) off and back on, the display is back. This happens when using the internal LCD at 1280x800 or my external monitor hooked up via E-Dock.
I've tried a couple different monitors, and they all work fine. I have another hard drive for this machine that I have Windows 7 loaded on, and it works for hours and hours without exhibiting any video related errors.
Is there something wrong with the Intel driver included with F11 or is there something else I should look at?
