The problem isn't that there is no support for interlaced video modes. There IS support for interlaced video modes. The problem is that it DOESN'T WORK. That's actually a good thing, because it means that the fix is likely to be a fairly simple adjustment to existing code, rather than writing new code to add new function. I don't get any error messages stating "unsupported video mode", or any such thing. There is no indication from looking at the logs that there is anything wrong. I just get a black screen. Actually, now that I think about it, this bug report has probably been sitting on the wrong queue all this time. I reported the bug against package xserver-xorg-video-nouveau, which is a user-space X driver. But the driver uses kernel mode setting (KMS) to set the actual video mode. The same bug can be reproduced by using the following kernel boot parameter: video=VGA-1:1024x768@87i Except that in this case the blank screen is produced on the frame-buffer text consoles (vt1-vt6) instead of the X server console (vt7). This tells me that the bug is on the kernel-space side rather than the user-space side. If I were the maintainer, that would probably have been the first thing I would have tried to determine. The bug could be in the nouveau kernel module, or perhaps in more-generic KMS code. To determine if the problem is nouveau-specific, I would need a non-Nvidia video card whose driver also uses KMS. But that brings up another issue, which is reporting bugs upstream. The official Debian policy is "Don't report bugs upstream". I quote from http://www.debian.org/Bugs/Reporting: Don't file bugs upstream If you file a bug in Debian, don't send a copy to the upstream software maintainers yourself, as it is possible that the bug exists only in Debian. If necessary, the maintainer of the package will forward the bug upstream. But if the bug is clearly in upstream code, and the maintainer is ignoring the bug report, what else can one do? -- .''`.
