we must calculate the ram from MB to KB in order to use it in Videoram option; here the table:
16 -> 16384
32 -> 32768
64 -> 65536
128 -> 131072
256 -> 262144

/etc/X11/xorg.conf 파일 생성.
(되도록 필요한 부분만 간단히 작성한다. 요즘은 보통 파일이 없기도 하다.)

x@pughome> cat /etc/X11/xorg.conf
...
Section "Device"
Identifier "Configured Video Device"
Driver "intel"
Option "AccelMethod" "UXA"
VideoRam 262144

비디오 카드 드라이버 업데이트.
$ sudo apt-get update
$ sudo apt-get dist-upgrade

X를 재시작 한다.

“시작” – “시스템 설정” – “데스크탑 효과” 에서
각 종 3D 데스크탑 효과를 설정할 수 있게된다.
