LCD saya capable untuk resolusi sampai 1280x800(paling nayman dimata) bahkan lebih.
tetapi kalau di perintah xrandr -q 
hasilnya seperti dibawah. xorg.conf ditambah manual tidak ngefek.
ada yang bisa membantu?

-------------------------

root@tux-desktop:/home/tux# xrandr -q 
Screen 0: minimum 320 x 200, current 1360 x 768, maximum 8192 x 8192
VGA1 connected 1360x768+0+0 (normal left inverted right x axis y axis) 0mm x 0mm
   1440x900       59.9 +
   1600x1024      60.2  
   1280x1024      60.0  
   1280x960       60.0  
   1360x768       59.8* 
   1152x864       60.0  
   1024x768       60.0  
   800x600        60.3     56.2  
   640x480        59.9  

Bagaimana cara nambahnya di xorg.conf ya?
existing xorg.conf:

-------------------------

Section "Device"
Identifier "Intel Corporation Mobile GM965/GL960 Integrated Graphics Controller"
Driver "intel"
BusID "PCI:0:2:0"
EndSection

Section "Device"
     Identifier    "Configured Video Device"
     Driver        "vesa"
EndSection

Section "Monitor"
Identifier "Generic Monitor"
HorizSync 28-64
VertRefresh 43-60
Option "DPMS"
EndSection

Section "Screen"
        Identifier      "Configured Screen"
        Monitor         "Generic Monitor"
        DefaultDepth 24
        SubSection "Display"
                Modes "1440x900" "1280x1024" "1280x800" "1024x768" "832x624" "800x600" "720x400" "640x480"
        EndSubSection
EndSection

klo saya menggunakan versi gui
pake lxrand

simple monitor config tool for LXDE
This is a very basic monitor config tool utilizing XRandR. It can let
you change the screen resolution on the fly.

Saya sudah berhasil menjadikan resolusi saya ke 1280x800 
Urut-urutan langkah ada dibawah. cuman masih bingung cara mempermanenkannya di xorg.conf
Ada yang bisa nolong?
Trims.

root@tux:/home/tux# gtf 1280 800 60.0
  # 1280x800 @ 60.00 Hz (GTF) hsync: 49.68 kHz; pclk: 83.46 MHz
  Modeline "1280x800_60.00"  83.46  1280 1344 1480 1680  800 801 804 828  -HSync +Vsync


root@tux:xrandr --newmode "1280x800_60.00"  83.46  1280 1344 1480 1680  800 801 804 828  -HSync
root@tux:xrandr --addmode VGA1 1280x800_60.00

solved.

dengan menambah perintah


xrandr --newmode "1280x800_60.00" 83.46 1280 1344 1480 1680 800 801
804 828 -HSync

xrandr --addmode VGA1 1280x800_60.00


xrandr --output VGA1 --mode 1280x800_60.00

xrandr --newmode "1280x800_60.00" 83.46 1280 1344 1480 1680 800 801
804 828 -HSync --> didapat dengan mengetik perintah: gtf 1280 800 60

diselipin di /etc/gdm/Init/Default
sebelum
initctl -q emit login-session-start DISPLAY_MANAGER=gdm

sekarang resolusi 1280x800 (16:10) tersedia di pilihan
