nothing I have done so far has allowed me to have a virtual screen on
the LVDS larger than 1024x600 and the above didn't work.

Presently xorg.conf on my Aspire One looks like this...

Section "ServerLayout"
        Identifier     "single head configuration"
        Screen      0  "Screen0" 0 0
        InputDevice    "Keyboard0" "CoreKeyboard"
EndSection

Section "InputDevice"
# keyboard added by rhpxl
        Identifier  "Keyboard0"
        Driver      "kbd"
        Option      "XkbModel" "pc105+inet"
        Option      "XkbLayout" "us"
EndSection

Section "Device"
    Identifier  "Card0"
    Driver      "intel"
    VendorName  "Intel Corporation"
    BoardName   "Mobile 945GME Express Integrated Graphics Controller"
    VideoRam    229376
    Option        "MonitorLayout" "LVDS,VGA"
    Option        "Clone" "true"
#    Option        "AccelMethod" "EXA"
    Option        "NoAccel" "true"
    Option        "MigrationHeuristic" "greedy"
    Option        "CacheLines" "1980"
    BusID       "PCI:0:2:0"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        DefaultDepth     24
        SubSection "Display"
                Viewport   0 0
                Depth     24
                Modes   "1280x1024" "1024x768" "1024x600"
                Virtual 2048 2048
        EndSubSection
EndSection

and I have had various sizes in 'Virtual' from 1024 768 and 1280 1024
and have tried disabling the 'Modes' line altogether or just had it with
"1280x1024" (my 19" display) but nothing has worked. I have been mostly
testing things with just the built-in display because that is where I
want the larger virtual screen.
