# /usr/share/qt/examples/touch/pinchzoom/pinchzoom -qws

수행하면 됩니다. 

디스플레이 관련 (Rotation)

export QWS_DISPLAY=Transformed:Rot270:VNC:LinuxFb

위와 같이 세팅을 하면 270도 Rotation 됩니다. 

#####

부팅 시 자동으로 환경 설정 위해서 파일 시스템에

/etc/profile.d

에 만들자 

Qt_config.sh 이름으로 다시 만들자

# mkdir /etc/profile.d

# vi /etc/profile.d/Qt_config.sh

#!/bin/sh

echo "Qt4 TSlib Environment Start"

echo "-----------------------------"

export QWS_SIZE=800*480

export QWS_DISPLAY=Transformed:Rot270:VNC:LinuxFb

# chmod 755 /etc/profile.d/Qt_config.sh

리부팅 후 이상없이 동작한다.
