[nwst-dev] New patch, fixes X in 16/32bpp

[Jochen R. <jo...@pa...>]

I posted a new patch to the website, along with my fb.modes
file and my XF86Config-4.

This new patch gets the fbdev X server running in 16 and 32bpp
mode. Turns out that my understanding of pixel formats in fbdevs
was not correct.

The patch for fbi included in my last email to the list does
not work with native pixel format fbdevs, so please disregard
it.

I am running this with XFree86 4.1.0-16 at 1024x768-60-16.

The 15bpp modes end up running in 16bpp, but with the 5:5:5
scheme, not 5:6:5, so the colors are a bit weird. I think that
the mode lines in X need to get fixed for this.

To run X in over a 32bit fbdev mode, X needs to be told to use
24bits in the XF86Config-4 file.

The 800x600 modes work, but the timing is off. Again, I think
this is because of the mode line data.

800x600-60-16 works well if set by fbset, tested with vanilla fbi.

Let me know if you need any other information to test this.
