dear guys, I have a problem between my CentOS 5.5 (on Axioo notebook) and LCD Projector. When I connect my notebook to LCD Projector, it can detect my notebook. But when I press Fn + F7 to activate dual monitor between my notebook and LCD Projector it goes to blank screen. FYI, the LCD Projector is NEC but I don't know the series. I've tried to change display using dual head monitor but it has no effects. Do I need some driver?? and this is my xorg configuration : Section "Device" Identifier "Videocard0" Driver "openchrome" EndSection Section "Screen" Identifier "Screen0" Device "Videocard0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 Modes "1280x800" "1024x768" "800x600" "640x480" EndSubSection EndSection Hope you guys can help me. Thanks. Andrew. -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://lists.centos.org/pipermail/centos/attachments/20110911/ee52785a/attachment-0004.html>
