[alie]

Hi guys,

I got problem with my gnome/KDE screen resolution problem. i only have 1 options 640x480. i've changed my xorg.conf modes to "1023x600" "800x600" but still appears as 640x480

I had similar problem and fixed it by putting extra lines in section "Monitor":
Section "Monitor"
Identifier "Monitor0"
VendorName "Samsung"
ModelName "SyncMaster 2253BW"
HorizSync 30.0-81.0
VertRefresh 56.0-75.0
ModeLine "1680x1050" 146 1680 1784 1960 2240 1050 1053 1059 1089
Option "DPMS"
EndSection

My Section "Screen" looks like this:
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1680x1050"
EndSubSection
EndSection

You can generate ModeLine with gtf utility if you know your vertical refresh rate (usually 60Hz for laptops) as shown:

$ gtf 1024 600 60 -x

Another utility is xvidtune

OR you can use online ModeLine calculators (google: "modeline calculators")
One of them: http://xtiming.sourceforge.net/cgi-bin/xtiming.pl
Another one: http://www.arachnoid.com/modelines/

Usually monitor's (laptop's) manual contains data you need:
default resolution, horizontal sync, vertical refresh, maximum pixel clock (first value after ModeLine "1680x1050" 146 1680 ...)

Another fix you may want to try is this line in Section "Monitor":
PrefferedMode "1024x600" or whatever your maximum resolution is.
