[Bug 33674] New: KMS, kernel, Second Monitor becomes complete blur when loading fullscreen GL
https://bugs.freedesktop.org/show_bug.cgi?id=33674
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).

--- Comment #1 from Alex Deucher agd5f@yahoo.com 2011-01-28 15:34:53 PST --- did you update anything other than the kernel (mesa, ddx, etc.)? If it's just the kernel can you bisect?

--- Comment #2 from Øyvind Sæther oyvinds@everdot.org 2011-01-29 05:28:56 PST --- 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.

--- Comment #3 from Øyvind Sæther oyvinds@everdot.org 2011-02-21 19:43:16 PST --- Created an attachment (id=43633) --> (https://bugs.freedesktop.org/attachment.cgi?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.
