[Linux-visws-devel] SGI VWS framebuffer

[Florian B. <bo...@un...>]

Hello all!

Now that CeBit is over i had more time to play with my 320. I tried somer things
around X and framebuffer. My current state is this:

- The framebuffer is 16 bit mode works in 556/5551 bit mode. This mode works OK, X
   basically supports this too. On x86 platforms the XRender extension doesn't support
   other color bits mode than 565. This is the reason why gtk based software like
   gnome* etc. doesn't work.
- In 32 bit mode the framebuffer at least works, but i'm not shure if it works correctly.
   That what i get as output from fbset looks correct. (RGBA mode with 8 bits/color each)
   X -fbbpp 32 starts with a depth of 24, the weight looks ok, but i have no red
   in any pixel. Assuming X works correct in 32 bit mode i think this is a bug in the
   framebuffer code. I looked around a little bit, but i had no success bringing any
   red pixel at the screen in 32 bit mode :-/

If someone with some more experience with framebuffer code than me would look at this,
maybe he could fix this bug faster than me stumbling around and flipping bits :-)

Greetings

Florian
