Acer Inspire Aspire 5920 laptop with Intel Corporation Mobile
GM965/GL960 Integrated Graphics Controller (rev 03).

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,
