After having been happy with arch linux on my desktop for almost 12 hours, I'm now configuring it for my laptop. I'm now working on my XFree86 configuration, and I've hit a snafu. I have no idea what the horizontal & vertical sync ranges ought to be. I never got any monitor documentation with my laptop, and the technical specifications provided by gateway (the manufacturer; not very OSS friendly hardware, and I wouldn't recommend it to anyone getting a new computer) (on the other hand, the boxes are very pretty) are a little bit lacking.
Consequently, here is everything I can dig up. Is there anyone generally familiar with the kind of frequencies that modern laptop monitors can handle, who can give me a good idea of some values to use?
We've got:
15.0-inch active matrix (TFT) LCD color display
Maximum panel resolution: 1024 × 768
Maximum color depth: 32-bit (16.7 million colors)
LCD supported video modes: XGA
LCD maximum refresh rate: 60 Hz
Thanks!

my lcd-config looks like this:
Section "Monitor"
Option "CalcAlgorithm" "CheckDesktopGeometry"
DisplaySize 305 230
HorizSync 28-95
Identifier "LCD"
ModelName "FlexView 1600X1200"
VendorName "IBM"
VertRefresh 52-82
# UseModes "Modes[0]"
ModeLine "1600x1200/60Hz" 162 1600 1664 1856 2160 1200 1201 1204
1250 +HSync +VSync
Option "DPMS
EndSection
but the data i got from the manual, so it's not guessing but knowing
you can try the refresh and sync rates i use if nobody answers specific for your machine --- i know this settings work on 4 different lcd's for sure and never heard that they made trouble
instead of the Modeline (i use), i suggest you to write modelines and then just include the Modes-section you wrote to the monitor section (the out-commented line i added)
would be better you get other replys specific on your hardware - mine is more general, sorry

This works on my laptop (also 1024x768).

When you use xf86cfg, you can always choose configs that do 1024x768 at 60Hz - the rest is automatic.
One thing to note about laptops : you are always safe when choosing refresh rates of 60Hz (they don't really work like CRT's of course, so you can safely chose this low refresh rate)
