無意間看到的，使用Nvidia顯示卡，用tvout boot時沒有畫面時，可以試試修改
geexbox-generator-0.xx\iso\GEEXBOX\etc\init.d\tvout

# There is no possibility of tv cable autodetection with nvtv so
# tvout is not enabled automatically. Uncomment the following lines
# to have nvtv tvout enabled at boot.
#nvtv $NVTV_ON >/dev/null 2>&1
#echo "" > /var/tvout
把那2行註解去掉試試，照說明是說可以在boot時開啟tvout的功能
改成
nvtv $NVTV_ON >/dev/null 2>&1
echo "" > /var/tvout
