Re: nvidia fb 0.9.0

Re: nvidia fb 0.9.0
I saw earlier posts about this, but never heard any resolution... Upgrading to a 2.4.2 kernel, my Riva128 based video card behaves strangely in X; certain colors are dark. The thing that confuses me is that not All colors are dark; just some of them. Redrawing parts of the screen changes luminosity in those areas. e.g. in windowmaker, some menus are dark, some are normal. A background set by xv is normal, but wmsetbg is dark, etc. Is this a known problem? Are there work-arounds?

This is in 16bit and 24bit modes. I have been told the Riva hardware can be programmed to expect 8 bit or 6 bit color registers. Rivafb < 0.7.2 used 6 bit color registers, but the hw was programmed to 8 bit registers on TNT/TNT2. That was causing the so called 'dark console' bug. Rivafb 0.9.2 begins to utilize 8 bits on Riva 128, but the XFree86-4.0.1 server uses only 6 bits of them so your desktop's brightness is 1/4.

I've tried to reproduce your problem, but I failed. Rivafb 0.9.2 on Asus V3000 (Riva 128) with nv driver (from XFree-4.0.1g, Debian Woody) works fine for me. Would you like to try out some other XFree versions too?

Not yet, we have to write that patch first... :) I'll grab an XFree source soon. Please test other color depths too: 15bpp and 32bpp. Thanks!

You are right, it's ver 0.9.2 for the fb. Where can I get the patch? Should I upgrade to XFree86-4.0.2?

The table below summarizes the depth of color registers in 8bpp mode: | Riva 128 | Riva TNT and higher +--+ XF86| 6 bit| 8 bit +--+ rivafb < 0.7.2 | 6 bit| 6 bit 'dark console' +--+ rivafb 0.7.3| 6 bit| 8 bit +--+ rivafb 0.9.2| 8 bit| 8 bit +--+ The Riva hardware can be programmed to expect 8 bit or 6 bit color registers. Rivafb < 0.7.2 used 6 bit color registers, but the hw was programmed to 8 bit registers on TNT/TNT2. That was causing the so called 'dark console' bug. Rivafb 0.9.2 begins to utilize 8 bits on Riva 128, but your X server uses only 6 bits of them so your desktop's brightness is 1/4. Now Riva 128 has a 'dark X' bug. :) The X server should be patched. Which X server/version are you using?

nvidia fb 0.9.0
I gave upgraded to 2.4.2pre on my RH7 box and while using riva-128 fb noticed when in X all the white parts of my desktop are to dark, it is almost unreadable. I think it might have to do with video timing, is there a way to fix this?
