This is my config:
Option "PageFlip" "yes"
Option "MonitorLayout" "CRT,LFP"
Option "AccelMethod" "XAA"
this is from log file.

I've also played with CacheLines. The result was that instead of allocation
37888kB for framebuffer only 21000kB has been allocated but for textures still
only 1392. Do not know why.
