[ale] Xorg rant

[Jim Kinney]

5MB is one screenfull of pixels @24bits/pixel. So 32MB is 1 current screen
plus the next 4 in buffer. So the next screen is just a pointer change.
HOWEVER they still have to be _sent_ to the graphics controller chip.

If it's slow, it's because it's system RAM and not video RAM. Using system
ram for video forces every video bit to also go back through the RAM
controller chip and the cpu (may dodge the cpu on some board/controller chip
combos). It's the major drawback to the process. If you need speed on
graphics, get a video card that uses dedicated vram.
