My laptop is Compaq presario cq42. I tried to connect my laptop (using ubuntu 11.04) to my TV with VGA cable. The bootloader menu and login screen are displayed on TV but after logged in, it showed NO SIGNAL. I tried to change resolution of TV but nothing change (do it in both Monitors and ATI analys control (admin)).
Here's my /etc/X11/xorg.conf :
