The maths on this is pretty simple - the number of bits you need to store your image is with * height * bpp. Divide by 8 for bytes. So, 1024x768 = 786432 pixels, at 8bpp is < 1MB. Even at 32bpp, you're still running at < 4MB. Something's rooted somewhere. Of course, modern video cards use their memory for a lot more than storing the current image, but I've never seen a card modern enough to have 32MB of video memory that can't push itself to 1600x1200 or so. Either your card is lying, or you've got something squirrelly going on in your X config. Does /var/log/XFree86.0.log tell you *why* it's not giving you any sensible modes? - Matt -- SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html
