That's what I though too, but I've tried this on 2 different 712's and have the same behavior. What is strange is that the framebuffer can display white text with no problem on the console (the default cursor is white). Also, under X, specifying #fefefe shows up as "almost white". Any other ideas? I thought that possibly the rgb.txt was not getting loaded, but I'm fairly certain that it is. _________________________________________________________ Do You Yahoo!?

But I assume you use the same framebuffer device on both?

I wrote (migrated) most parts of this stifb driver and it works perfectly without any color-problems together with the XFree86 fbdev driver here on my 715/64. The 715/64 has the Artist graphics chip too, so I suspect we just need some more initialization for the "older revisions" of the Artist chip in the 712 machines.

It's possible the 715/64 firmware and 712 firmware behave differently. ie artist chip initialization by firmware could be different. I'm assuming stifb doesn't send a RESET command to the Artist chip directly and start initializing from scratch. grant Grant Grundler parisc-linux {PCI|IOMMU|SMP} hacker +1.408.447.7253 ^ permalink raw reply [flat|nested] 6+ messages in thread

Actually, yes. The Artist (in all 712's, some 715's and some 725's) has 2 colormaps. _________________________________________________________ Do You Yahoo!?
