(Sorry about the time lag. Another post buried in my list folder.) Amancio Hasty: |Niklas Saers: | |Amancio Hasty: | |> I don't think we support 24bit for the Matrox millenium .

I mean, about everything else works | |perfectly in 24 bit and XFree86 with my Matrox. :) | | |I forgot :( When I added the pixel format stuff, best as I could figure, only one of the two byte swapped packed 24bpp pixel formats was attainable with the Bt848 (works on S3 chipsets like my Virge/VX). You can see the supported driver RGB pixel formats using fxtv -debug startup: Supported RGB Capture Pixel Formats: bpp Bpp RGB Masks Swap --- --- ---------------------------- ---- 15 2 00007c00, 000003e0, 0000001f NB 16 2 0000f800, 000007e0, 0000001f NB 24 3 00ff0000, 0000ff00, 000000ff B <----------- 24 4 00ff0000, 0000ff00, 000000ff NBWb Which frame buffer format can't be queried in XFree 3.3.1 and prior versions (I've been told that it might be in a future version though) so Fxtv tries to guess the Bpp from the Display pixel formats or visual depth, and it makes the user specify the pixel format swaps via resources: Try these two commands: fxtv -xrm "Fxtv.bswap3Bpp: true" fxtv -xrm "Fxtv.bswap3Bpp: false" one of them will give you DirectVideo. If the colors look good, great -- keep it. If the colors are "psychedelic", the frame buffer format of your card is the unsupported Bt848 24bpp swap format. Note: it may be that the Millenium supports both 24bpp frame buffer orders, but that your X server just configuring up the one the Bt848 doesn't happen to support.

Possibly 32bpp frame buffer format in reality? Don't know without more info.
