I have an Intel D945GCLF2 desktop board and I'm unable to use the tv-out feature. With the Intel drivers pre 2.7 the tv-out didn't work, with the latest 2.7 release it show only black and white images, because the only format used is the default NTSC. The driver is unable to switch tv format neither via xrandr nor xorg.conf, it doesn't accept the TV_FORMAT option.
Yes, 2.7 only adds NTSC support for SDVO-TV (which is used by D945GCLF2).
I have managed to get the SDVO-TV working in PAL mode, by applying the patch found in: http://lists.freedesktop.org/archives/intel-gfx/2009-April/001964.html and then adding the Option "TV_Format" "PAL-G" to my xorg.conf ( I don't have my conf file here with me, but I believe this the right option) I also added new kernel to my Ubuntu 9.04, since there are some patches for SDVO, but I am not sure if it is needed, see: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=history;f=drivers/gpu/drm/i915;hb=a4f1cb9f3c42e5d278b0678ed5225d9331a8dcff patches from Zhenyu Wang Sometimes it happens that TV-OUT is not in PAL, but after switching to some VT (like 1) and switching back to X solves the problems. Hope that helps. Matej
Hi Marco With latest 2D driver, could you please try in UMS by setting i915.modeset=0, and upload xorg.log with modedebug option on? Thanks Ma Ling

Hi, I tried this patch on my board D945GCLF2 and result is good. My TV is connected during S-VIDEO connector (composite out, PAL). Video screen is static and "xrandr --output TV-1 --set TV_FORMAT" returns correct result. One drawback is that my screen is black&white. I tried settings in "Windows XP" and screen was colour. The best result in Linux was with settings PAL_60 but in this case was not colour stable (sometimes B&W and sometimes Colour). Colour was not sharp and than recognition was difficult. My configuration: D945GCLF2 2GB RAM Ubuntu 9.04 Intel driver - xorg-intel - git version patch drm - git version Best regards Mirek
