Hi, I compiled the kernel from your git repro to test interlaced output with my Clarkdale (H55) Chipset. After installing and reboot I put the interlaced line to my xorg.conf and activate them (first by xorg.conf and after that by lxdm resolution set tool). I only get a screen full of colored stripes after switching from progressive to interlaced mode. My TV shows 1080i as input mode. After that I read all mode lines from my TV by using the xorg server log and tried every interlaced modeline I found but always the same striped screen. To get sure that I use correct modelines I checked them with an plugged in card from another brand and it works immediately. Hardware: - Intel H55 Chipset with Core I5 661 and another one with Core I3 540 CPU - HDMI and VGA connected to my TV (VGA didn't show any screen with x and interlaced modes) - Samsung LE32A557 TV Software: - Arch Linux with your kernel 3.3.0 rc1 (compiled yesterday) - xorg-server 1.11.3-1 - xf86-video-intel 2.17.0-2 @list: Anyone with Clarkdale and running interlaced mode?
