[gentoo-user] CONFIG_DRM_I915_KMS lcd becomes gray after sleeping

Hi,
After sleeping my laptop becomes grayish transparent.
It happens from time to time, no always.
The only way to handle this , is to restart the computer.

Any thoughts?

Regards,
Kfir

Try also enabling backlight control drivers. 

I also have an Intel laptop and it works fine, and the backlight
controls also work.

Can you restore the backlight with setpci?

setpci -s [device id] F4.B=[00-99]

I think I found the problem but I'm still not 100% sure.
Its the "fade to black when blanking" of xscreensaver.
When my laptop goes to sleep, it issues lock command which in turn will
sometimes will fade the screen. I think its a bug of the fading.
I disabled this feature.
I'll see if it happens again.

Thanks for your help,
Kfir
