The screen randomly blinks to black and then comes back within a second. Earlier it happened only when I logged in to GNOME, but in the past one or two months it happens randomly (especially on continuous CPU usage, in every 30/60/90th… seconds).

The error message on each blink from everything.log:
kernel: [drm] nouveau 0000:01:00.0: DDC responded, but no EDID for VGA-1
kernel: [drm] nouveau 0000:01:00.0: Load detected on output A

My video card:
01:00.0 VGA compatible controller: nVidia Corporation NV17 [GeForce4 MX 440] (rev a3)

Package versions:
libdrm 2.4.23-2
xf86-video-nouveau 0.0.16_git20101217-1
xorg-server 1.9.4-1
libgl 7.10.1-1
mesa 7.10.1-1

I think that this bug was reported to upstream by two another Arch Linux user:
This task depends upon

Reason for closing:  Upstream
Additional comments about closing:  One reporter said in the upstream report it's fixed by cable replacement. No more responses in several months. Nothing we can do here.

On some blinks the following message also shown in kernel everything.log:
kernel: i2c i2c-3: readbytes: ack/nak timeout

Confirmed, Geforce4 MX440 here...

Just an FYI:

Currently I use a custom kernel with the above mentioned patch, and I get blink once a day only, not in every 30/60/90th seconds.

Can you confirm that this is solved in kernel 2.6.38 from testing?

I tested now, and this problem is still happens with kernel 2.6.38.
