           Summary: KMS, kernel, Second Monitor becomes complete blur when
                    loading fullscreen GL
           Product: DRI
           Version: XOrg CVS
          Platform: x86-64 (AMD64)
        OS/Version: Linux (All)
            Status: NEW
          Severity: critical
          Priority: highest
         Component: DRM/Radeon
        AssignedTo: dri-devel@lists.freedesktop.org
        ReportedBy: oyvinds@everdot.org


On affected system:

1. Load fullscreen OpenGL something which thinks fullscreen means both attached
monitors. This includes kwin and warzone.

2. Kernels 2.6.37-git15 2.6.38-rc1-git2 2.6.38-rc2-git7 show expected on first
monitor and complete blur on second monitor. Total messy blur. Everything works
perfectly with stable 2.6.37-gentoo kernel. I do not know what happened with
<=2.6.37-git15, but I do know 2.6.37-git15 kernels and later are defective.

It would be nice if someone could make two monitors work with OpenGL again
(working kwin is nice).

did you update anything other than the kernel (mesa, ddx, etc.)?  If it's just
the kernel can you bisect?

I update git x11-libs/libdrm, x11-drivers/xf86-video-ati and media-libs/mesa
frequently.

I do not know if new kernels work with older version of libdrm/video-ati/mesa,
I had a recient version of those when I noticed, update to later and still no
second screen so I tried an old kernel and it worken, then I tried all the
newer ones mentioned.

Created an attachment (id=43633)

How totally broken fullscreen OpenGL applications look

kwin and other fullscreen opengl applications still show a total blurry mess on
the second monitor as of kernel 2.6.38-rc5-git4.

Completely broken and useless.
