Hello list. How I can access the video memory directly from user
space? I tried to map the framebuffer (/dev/fb0) using mmap() and
ioctl(), but I have not been successful. Really I want to make a copy
of the contents of video memory and save it ?as an image. have any
suggestions?

Hi, probably not the brightest idea, but have check and try to read
(carefully) these memory area, such as:
$ cat /proc/iomem  | grep -i video
000a0000-000bffff : Video RAM area
000c0000-000c7fff : Video ROM
