For reference, the work-in-progress tree is at http://cgit.freedesktop.org/~ickle/linux-2.6/log/?h=sdvo commit 5cb6a67a59f0ad645a7925e0c26728093d460233 Author: Chris Wilson <chris@chris-wilson.co.uk> Date: Sun Jul 18 20:01:36 2010 +0100 drm/i915/sdvo: Add dot crawl property This property is slightly unusual in that it is a boolean and so has no GET_MAX command. Reference: Bug 28636 - missing TV parameter "Dot Crawl freeze" https://bugs.freedesktop.org/show_bug.cgi?id=28636 Signed-off-by: Chris Wilson <chris@chris-wilson.co.uk> Applied to Eric's for-linus branch. The abovementioned patch is included in kernel 2.6.36-rc2. "Dot Crawl freeze" is still not implemented in the driver 2.6.36-rc2.

Afaik it _is_ implemented. Note that you need and SDVO TV interface card that actually supports it. The one in the xrandr dump doesn't have any advanced TV properties, so it likely doesn't have the "dot crawl freeze" property either. |
