           Summary: Detects Load on output and blinks screen ~30secs
           Product: xorg
           Version: unspecified
          Platform: Other
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Driver/nouveau
        AssignedTo: nouveau-PD4FTy7X32lNgt0PjOBp9y5qC8QIuHrW@public.gmane.org
        ReportedBy: mmendez534-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org
         QAContact: xorg-team-go0+a7rfsptAfugRpC6u6w@public.gmane.org


Card is GeForce 7100 GS
OS is Arch latest.

Problem:
Every 30 seconds the monitor connected via VGA blinks off, and then comes back
on. dmesg output shows '[drm] nouveau 0000:01:00.0: Load detected on output A'. 

The resolution is also incorrectly detected/set to '1024x768', when '1920x1080'
should be the preferred. If I add the other monitor's (DVI) preferred mode to
the VGA and then set that as the mode it works fine.

I have seen bugs 26800, and 29455 but they don't quite match my problem. I
don't want TV out and my resolutions are fine after I add the mode to the
output and select it. Turning off TV-1 doesn't fix the problem.

Same here, the screen randomly blinks out in every 30/60/90th… seconds. (I also
use Arch Linux)

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

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

Package versions:
kernel26 2.6.37.3-1
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 reported this bug on Arch Linux bugtracker also:

I have same problem, card is
01:00.0 VGA compatible controller: nVidia Corporation NV25 [GeForce4 Ti 4200]
(rev a3)
OS is Gentoo.
I tried
Nouveau kernels 2.6.38-rc8-g7972f91 and 2.6.37-rc3-gd095e23,
xorg-servers 1.9.4, 1.9.5 and 1.10.0,
xf86-video-nouveau 0.0.16_pre20101130 and git 92db2bc.

Nothing helped, so I tried proprietary drivers 96.43.19 and noticed line
[    30.567] (WW) NVIDIA(GPU-0): Unable to read EDID for display device CRT-1
This lead me to trying i2cdetect and indeed on all 3 i2c adapters there is
nothing on adress 0x50, where EDID should be. Any ideas?

Turns out in my case problem was caused either by bad cable or dust in the
monitor, after dusting monitor and manipulating with the cable, EDID is
detected again, so sorry for the noise.

Anyway, should really Nouveau blink the monitor every 30s when it does not
detect EDID?

I have the same problem with GeForce GTX 460 and nouveau. And indeed, even
official nvidia driver doesn't find EDID for the screen which blinks with
nouveau. Still, binary nvidia drives that monitor OK, so nouveau should too.

I think it has been fixed in upower with this commit:

 Add an option for polling dock devices in UPower.conf, defaulting to false

--- Comment #11 from Ilia Mirkin <imirkin-FrUbXkNCsVf2fBVCVOL8/A@public.gmane.org> ---
Sounds like the bug here is that nouveau causes the VGA display to blink on/off
when checking whether it is connected. (And, to exacerbate the issue, there's
something polling every 30s to see if the monitor is connected/what modes it
has or something.)

Could someone with an affected monitor try to

cat /sys/class/drm/card0-VGA-0/status

(or whatever card/connector the thing is on)

and see if that action causes the monitor to blink on/off? If not, check
/sys/.../modes and .../edid and .../dpms. I'm guessing at least one of those
will cause the blinking issue.

My understanding of the VGA DDC stuff is that the monitor doesn't even have to
be powered on in order to get at that stuff (I guess power is supplied in the
VGA cable itself), much less have to try to show a picture. Although perhaps
not all monitors comply with that ideal.

BTW, please be sure to test it out with the latest kernel, just in case this
has been fixed.

I can confirm that blinking issue after cat /sys/class/drm/card0-VGA-0/status
every ~30 seconds. I'm using nvidia 7300 gt. do you need more data?

I'm very confused by your comment. Does cat'ing the status cause an immediate
blink, yes or no? (Your comment, taken literally, seems to imply that things
are all fine, then you cat the file, and then the blink happens every 30s. This
seems unlikely.)

What kernel version are you using?
