Acer aspire 1360, can get 1280*800 in windows but not in Linux

[TimL]

I'm having this same resolution problem on an Acer Aspire 1520. The
resolution is stuck at 1024x768.

When I first installed Ubuntu, the standard 'nv' driver was allowing me
to display at the proper 1280x800 resolution, but since installing the
nvidia-glx package, the res is stuck at 1024x768

Here is my XF86Config (relevant sections):


Code:
--------------------
    
  Section "Device"
  	Identifier	"NVIDIA Corporation NV36 [GeForce FX Go 5700]"
  	Driver		"nvidia"
  	BusID		"PCI:1:0:0"
  	Option          "RenderAccel"           "true"
  Option          "NvAGP"                 "1"
  EndSection
  
  Section "Monitor"
  	Identifier	"Generic Monitor"
  	HorizSync	28-64
  	VertRefresh	43-60

  EndSection

  	EndSubSection
  	SubSection "Display"

  		Modes		"1280x800"
  	EndSubSection
  	SubSection "Display"
  		Depth		8
  		Modes		"1280x800"
  	EndSubSection
  	SubSection "Display"
  		Depth		15
  		Modes		"1280x800"
  	EndSubSection
  	SubSection "Display"
  		Depth		16
  		Modes		"1280x800"
  	EndSubSection
  	SubSection "Display"
  		Depth		24
  		Modes		"1280x800"
  	EndSubSection
  EndSection

Does anyone have any ideas? I've been searching for ages now...

Thanks,

Tim
