Thanks for that, I'll have a look.

It's just that vga_setlinearaddressing doesn't work at all for me and I can't figure out why.

I only have the source (pre1.9) because I wrote the nv3 support for it. I have no idea where to get hold of it. I could put it on my web page if you're interested. The problem is that the textmode I'm in is 132x50 which has a 40Mhz pixel clock. Svgalib when switching to 320x200 doesn't notice this and so I get a mode with a 112Hz refresh rate. I partially fixed this by commenting out the lines that called the VGA setmode code. > For an explanation, see a post with subject "funny mmap() behaviour" > By Christian Groessler on 18 September, either to linux-svgalib, or to > linux-kernel I'll look into it. > > 4. /dev/mem is opened in several places and yet there > > is __svgalib_mem_fd?

I noticed this when it got into an infinite loop opening and mmaping /dev/mem. It the framebuffer support new or something? I also have two more general questions: 1. Can I have svgalib search for a new console when starting up while leaving the text output where it was. It would make debugging a lot easier. 2. I think your *secret* snapshot area is on altavista. Something that looks like it I found on www.uni-essen.de. Is that it? 3. Also it seems that the default palette is all black. Is this just me or what? It took me a long time before I figured that one out. 4. Also you noted a question whether the card could do 24Bit colour. Yes it can, but only with 4 bytes per pixel Thanks for your reply...
