Thanks.  Let's track them separately: Mike's effect will continue to
be tracked at #605318, while Matt's is #641633.


OK - made a video with xvidcap and uploaded it to youtube but it does not  
show any interference.  Don't know if that itself is diagnostic.  For what  
it's worth, it is here:

Thanks.  Mike, do you experience the same?

Both:

 - can you describe the horizontal lines more?  Are they one pixel
   tall or are they thicker?  How quickly do they flash?  Are they
   always there or only sometimes?  Do they move?  Do they cover the
   screen or only part of it?  Can you take a photo?

 - do you have firmware-linux-nonfree installed?

 - can you reproduce this with a kernel from sid or experimental?  (To
   install one to try, the only additional dependencies that should be
   needed are recent linux-base and initramfs-tools.)

 - If so, please report this upstream at bugs.freedesktop.org, product
   DRI, component DRM/Radeon and let us know the bug number so we can
   track it.  (Don't worry about duplicating each other --- it's nicer
   to have the information for each machine separately and mark one as
   a dup if appropriate later anyway.)

 - otherwise, we can try to find the fix and backport it; if you have
   time to find the first working verison at snapshot.debian.org by
   the bisection method, that would be helpful.

Sorry for the slow response, and hope that helps,
Jonathan

Bug#605318: radeon: horizontal interference lines on screen

2011-09-14 Thread Matt Pandina 
I was able to record what the horizontal lines look like on my laptop using
my phone. I posted the video on YouTube here:
http://www.youtube.com/watch?v=jkFsyKGFYzw

The lines will come and go every few seconds.

I do have firmware-linux-nonfree installed.

I have not tried any additional kernels, I just know that I never had this
video issue with Ubuntu installed on the machine.

My workaround is to configure the display settings so the desktop is upside
down, at which point I get a prompt asking if I want to keep or restore the
new settings. While that prompt is up, the display still has the lines on
it, but as soon as I hit ESC to revert the upside down change, everything
goes normal and stays that way until the next cold boot (very rarely do the
lines come back after putting the laptop to sleep, and if it happens I can
just flip the display upside-down and back to fix it).

Thanks, this helps a lot.  My random guess at the moment is that this
is related to the bug described at ,
which was fixed upstream in v2.6.37-rc1.  There is a series of three
patches in that bug log that could be worth a try if you have the time
(see [1]).

Bug#605318: radeon: horizontal interference lines on screen

2011-09-12 Thread Mike Sumner 
Hi Jonathon, glad you are onto this.  The problem is much less on mine as  
each flash is only about 1-2 cms long and I guess 1px wide, and they only  
occur on certain parts of the screen on solid dark colours and appear to  
be completely random.  They vary in colour. They show up on the grey  
background of gwenview well, and on Chromiums top window frame, which I  
have dark blue, and that gets blue flashes. Strange, but I dont see any  
interference on my desktop background, which has a large area of solid  
black.  This is on a testbed install of Crunchbang Statler, which is  
pretty much pure Squeeze, for checking out stock kernels and open source  
drivers and have been trying to get a video screenshot to send to you but  
I can't get vnc2swf to work, as it bombs out with an error.  If I can get  
some video of it, I will send it so you can see exactly what it looks  
like.  firmware-linux-nonfree is installed.  I have not tried sid kernels,  
but I also have a testbed install of Mint LMDE (based on Testing), and the  
problem seems to be fixed in that with the current kernel and radeon  
driver, though suspend does not work properly if I remember correctly.


I have everything working perfectly on my Squeeze production install with  
this workaround, which is to use:


Kernel-2.6.34-2.dmz.3-liquorix-amd64 x86_64   +   Catalyst version 10.12.

Graphics info :
Card ATI Mobility Radeon HD 3400 Series X.Org 1.7.7 Res: 1600x900@60.2hz   
GLX Renderer ATI Mobility Radeon HD 3400 Series GLX Version 3.3.10317  
Compatibility Profile Context


This is the first combination of driver and kernel I found that works  
properly on this machine in Squeeze, including working resume from suspend  
to ram, so I am sticking to it on my production install.  I removed the  
stock debian kernel so I don't get updates to it any more when I upgrade.


I can do a new testbed install of straight Debian Squeeze and give  
feedback from that if it will help.


Cheers, Mike

Instead, that looks like a kernel problem, in DRM/radeon, reassigning
to the linux kernel.

I'd say the radeon DRM part of the kernel, since it works fine with a
newer kernel but not with an “older” one.

did you mean “I assume the problem lies in the kernel, which is the
only item changing when I'm moving from a distro kernel to another,
tweaked kernel”?

If my understanding is correct, that bug should be reassigned to the
linux-2.6 package.

Package: xserver-xorg-video-radeon
Version: 1:6.13.1-2+squeeze1
Severity: important
File: radeon

Short horizontal lines appear across the screen in quick flashes when using 
2.6.32-5-686.
I tried liquorix 2.6.36-1.dmz.1-liquorix-686 and get no interference, so assume 
the 
problem is the radeon driver.
