Monitor started to randomly blinking


Hi

I have Ubuntu 10.04, my laptop is ASUS k50ij, intel duo t3000, 2gb ram, 320 HDD, intel gma 4500M video card.

My problem is that a couple days ago my monitor had start blinking for a few seconds. Then it stops and begins the same behaviour let's say in next 2 hours. What am i missing here?

Another funny problem is that when i give more or less brightness to monitor the pop up window shows and giving "Power information: Laptop battery is charged".

thx for help

If you run a live-cd for a couple hours, do you get the same results?
My first thought is that this is a driver issue. Try a live-cd and see what happens

If you're turning up the brightness via the applet, the power info window is just an informational message. If your monitor has been behaving fine, and just started doing this out of the blue (without changing ANYTHING else), then your monitor may be going flaky.

Have you updated/changed anything lately? How old is the laptop?

Hi

Actually, monitor start blinking even in grub menu. So maybe this is not a driver issue. But this blinking is rare and most often happens then when i change brightness via buttons or powerON or powerOFF the laptop from adapter (AC).

Power information show on changing brightness via buttons, via applet doesn't.
I have tried older kernels and blinking appears there too.

My laptop is 14 months old.

Well, there aren't really any 'drivers' loaded during Grub, so if it's flashing there, I'd suspect the hardware.

Yeah, i guess too it is a hardware issue. It is weird that it happens in relation to power and brightness fn keys. Thx anyway
