I expect them to be the same (prgramming model) but don't know if they actually are. > Can you use the driver for Visual-FX aswell (AFAIK these are similar) ? They are not similar. Vis-EG is 1280x1024 8 bit. Vis-FX are all 24-bit color. FX2/4/6 have 3d acceleration and texture mapping functionality (AFAIK, Vis-FXe does not) I think Vis-FX can handle higher resolutions as well. > Packed pixel: > > If you see stripes it is very likely that you mix up PACKED pixels and > NONPACKED pixels. But I think that's what you already checked. I haven't. "PACKED PIXEL" is what the kernel currently hands back. I believe this works for Vis-EG/GSC on PA1.1 machines. > Mini-tiles/Packed pixel: ... > Interleaved: ... I don't think Vis-EG/PCI uses either of the above. > BTW, Is the color of the displayed picture alright ? I can't tell since the visible portions are only black.

Both STICON text and Tux are striped diagonally top-left to bottom right. > Try to use some test-pictures (e.g. all red, all green. all blue, > check-boxed, special patterns ...)! That's a good idea. I setup some GIF for that. > Actually I don't think I'm telling you any new stuff. > So let's stop here and I wish you good luck! For me, much of it is new. I don't know anything about FB layout. thanks, grant
