[Intel-gfx] Sony VAIO VPC-SA2 blinking/waves on LVDS

[Олег Герман]

Hello.

I have a VAIO VPC-SA2 laptop, with an Ubuntu 11.04 installed.
The problem lies in the strange screen (LVDS 1600x900) blinking/waves
( which is mostly
noticeable in grey gradients and causes eyes fatigue and pain after
prolonged use.
This problem does not occur with the VESA driver, Windows and other
outputs, but it's
reproduced in Fedora Core and Ubuntu 10.10/11.04/11.10 at X-window and
cosole (with i915 module). It is clear that the problem is in the
driver, but I can't determine the source of noise, it may be because
of the backlight, or the display-panel.

I captured how it looks like
