Screen flickers with Debian 7 (wheezy) on sony vaio x (GMA500)


I've installed debian wheezy (stable) on my soy vaio x (which runs a GMA500 display chipset).

The driver being loaded is gma500_gfx. the problem I'm having is that the screen randomly flickers (goes black) for a second or so, every minute or.

Any suggestions how to solve this? the laptop is unusable in this manner.

TIA

When that was happening on my HP desktop PC (Nvidia 9100 onboard graphics), it was because my Soyo monitor does not emit a proper EDID, and every time the message indicating such was emitted, the screen would flicker in a manner similar to what you're describing. Until the nouveau driver was fixed, I used the Nvidia driver

tnx.

The workaround I've found is to blacklist the gma500_gfx module.

The screen doesnt go black now, but graphics updates are very slow.

Cant say I'm happy with Debian :-(
