Re: [CentOS] x windows and i810 chipset -- you need interlace (1080i)

Oh, now you're talking about a completely _different_ issue. Your scanline is _invalid_.

Unless you pass "interlace", you're attempting to do 1080p! That requires well over 100KHz in horizontal scan!

Try this Modeline (1080i):

Modeline "1080i" 79.84 1920 2040 2200 2368 1080 1090 1106 1125 +vsync -hsync interlace

It still might _not_ work. Some chipsets (especially the i8xxG's) have MIT X11 drivers with a lot of limitations to reprogramming the timing. E.g., I have personally started avoiding any notebook with an i8xxG/9xxG in Linux for this reason.
