Just in case. First it seems that some "generic"
resolutions/frequencies, seen on default X config files, are badly
understood on some laptops. Screen gets seriously trashed in an ASCII
rainbow.
Besides I found an interesting feature on one notebook & recent
XFree-4.0.1 builds (4.0 didn't seem to have it). On an ATI Rage 3D I had
to COMMENT every reference to frequencies on the config file. It seems
that that chip "understood" internally the presence of a LCD monitor.
And X driver supported it. What lead me to this was the fact that X was
giving some phrase of this kind: "found settings on config. Overriding
chip internal (...) LCD monitor settings". I can't check that string
now, but, by commenting the freqencies, I managed to run X in all
supported resolutions/colors.
