photo of screen with pink line
When I boot my machine with KMS enabled, as soon as the mode is set the monitor displays a persistent pink line all the way to the left of the screen (photo attached) from top to bottom. The line is persistent even when X starts.
This is the case with:
...I haven't tested earlier ones. When I boot with "nomodeset" the problem goes away. lspci info:
01:00.0 VGA compatible controller: ATI Technologies Inc Juniper [Radeon HD 5700 Series]
Let me know if other info would be helpful.
I also see a pink/magenta line on the left. I haven't tried nomodeset yet, but will.

This is connected via HDMI, if that's relevant.
I tried connecting the monitor via both HDMI and DVI and got the same line. I'll note though that HDMI and DVI on this monitor are connected via the same port (it has a cable with an HDMI port on one and and DVI on the other).
The native resolution on this monitor is 1920x1080 too if that makes any difference.
The pink line also went away for me when I did nomodeset. FWIW, mine too is a DVI-to-HDMI cable, but it sounds like on Jeff's card, he also gets the line when using the analog cable, so that's not the issue. My resolution is 1920x1200.
FWIW, I decided today to return this card. The pitiful state of the radeon driver really made this a downgrade from my 3 yo. NVIDIA card. Maybe I can pick up one for a song once the radeon driver properly supports it ;)
I have identical video hardware (HD5770). I also have my HDTV (1920x1080) connected via HDMI, and a DVI monitor (1440x900). I'm using the Mesa Dri Experimental drivers.
I experience the same issue, pink line on left of screen.
I'll add my request to getting this resolved as I have a plasma and fear burn in.
Moving over to xorg-x11-drv-ati for debugging/further ideas.
This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle.
Changing version to '14'.
More information and reason for this action is here:
I reacquired one of these cards and when I boot to a 2.6.36 kernel, the pink line is now gone.
Also, I don't think this really belongs with xorg-x11-drv-ati as it's a kernel problem. It's visible even when X isn't running as soon as KMS kicks in.

So, we can close it, right? What's the current version of your kernel and xorg-x11-drv-ati?

There is a kernel part of the driver and userspace one ... we prefer to keep both parts together in one component. Kernel developers have enough of their bugs already and these bugs are fixed by Xorg developers anyway.

I suppose you can probably close with with a resolution of "rawhide":
Closing with resolution of RAWHIDE. Please reopen if you see this with more recent kernels (2.6.36 and up).
