Hi,
I am running CentOS 5.2 on Acer laptop, I try to display laptop screen on a LCD TV via VGA cable. It was fine while PC was booting in text mode, but as soon as I started X Window, the LCD TV has error "Unsupported signal, adjust your PC out".
How can I adjust or may be regenerate an xorg.conf for the LCD TV (Sony KDL-40V5500)?
Thank you.
Kind Regards,
Jupiter

Hi
Resolution?
Or, you have to configure something like xinerama or twinview. I not sure but I think twinview is a NVIDIA feature.

Some, like nvidia and ati provides gui tools to configure settings.

Acer Inspire Aspire 5920 laptop with Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller (rev 03).
Some, like nvidia and ati provides gui tools to configure settings.
I actually tried to run system-config-display --reconfig for Sony KDL-40V5500 LCD TV, it generated a new xorg.conf and I restarted laptop, but still could not run X window on LCD TV. Please correct me, but I thought if the xorg.conf is reconfigurated, it should work unless that the CentOS 5.2 does not support the type of Sony LCD?
Thanks for your help.
Kind regards,
Jupiter

Automatic configuration is not always perfect, you need to find out correct values for this kind of television. Just enter manually correct modelines using manual of tv. -- Eero

This is not an uncommon problem with flat panel displays, and is hardly limited to one distribution. Step one is to find out what resolutions, horizontal and vertical frequencies the internal display can handle. Step two is to find out what combinations the video chips can generate. Step three is finding out which combinations the TV can accept. Once you determine where all three sets overlap, you configure X to use the mutually acceptable options. You may end up with an unusable lowest common denominator doing this, so look into any multi-display options while you are collecting the data.
