Dell Latitude D520 Resolution

[dwessell]

Hi,

I have a Dell Latitude D520 that I can't get to go about 1024x768. There aren't other options. But I know that it's capable because it has higher options in Windows. Can someone point me in the right direction?

Here's my lspci:

My xorg log file shows:

[125563.848] (II) intel(0): Printing DDC gathered Modelines:

I ran through the xrandr process that is documented in the wiki and it adds the mode, but doesn't assign it to LVDS1.

dwessell@dwessell-Latitude-D520:/var/log$ xrandr

        h: width  1280 start 1360 end 1496 total 1712 skew    0 clock   63.6KHz
        v: height 1024 start 1025 end 1028 total 1060           clock   60.0Hz 

If I try and add the mode it fails:

dwessell@dwessell-Latitude-D520:/var/log$ sudo xrandr --addmode LVDS1 "1280x1024+60.00"
[sudo] password for dwessell: 
X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  149 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  29
  Current serial number in output stream:  30 

So as far as I can tell I need to either tell something to ignore the edid information reported, or make a manual xorg.conf entry. Is that correct? Is there good documentation that I'm not finding for this?

Thanks
David

AFAICT, unless you got the d520 with the premium screen (which supports 1400x1050), then 1024x768 IS the native resolution. http://www.notebookreview.com/default.asp?newsID=3150
