Alright guys here's the deal. I just installed Ubuntu and I'm working in Gnome at 640x480 resolution at 60hz. I am dual booting with Windows XP. In Windows I can achieve a resolution of 1152x864 with no problems.

Now I know what you're going to say. "Edit your xorg.conf file" I've been in there but I do not see the refresh rates. Here's what it looks like:

Section "Device"
Identifier "Intel Corporation 82865G Integrated Graphics Device"
Driver "i810"
BusID "PCI:0:2:0"
EndSection

Section "Monitor"
Identifier "hp 7500"
Option "DPMS"
EndSection

Section "Screen"
Identifier "Default Screen"
Device "Intel Corporation 82865G Integrated Graphics Device"
Monitor "hp 7500"
DefaultDepth 24
SubSection "Display"
Depth 1
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 4
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 8
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 15
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 16
Modes "1024x768" "800x600" "640x480"
EndSubSection
SubSection "Display"
Depth 24
Modes "1024x768" "800x600" "640x480"
EndSubSection

I've tried the 'sudo dpkg-reconfigure xserver-xorg ' method, but it never gives me a chance to select my monitor settings.

Any help would be greatly appreciated. I started using linux 2 days ago, so be gentle.

Thanks

I think that your ubuntu didn't configure your monitor correctly.

try to edit your xorg.conf:

Section "Monitor"
Identifier "hp 7500"
Option "DPMS"
VertRefresh 40-70
HorizSync 31.5 - 48.5
EndSection


We just have to set VertRefresh & HorizSync manually.

Bravo! That fixed the crap resolution problem. Now let me throw this one at you.

When I use Windows XP I get a resolution of 1152x864 @ 72hz. I would like to be able to use that here.

At the moment Ubuntu is running 1024x768 @ 85. Do you know how I can configure xorg.conf to let me run 1152x864 instead?

Thanks for all the help btw.

I'm happy if it worked.
Actually, I'm not sure that both value (VertRefresh & HorizSync) are correct for your monitor.
You have to find and then set it to the correct value to do better.
For 1152x864 resolution, you can try to edit xorg.conf again and then add 1152x864 at modes row:

for example:
SubSection "Display"
Depth 24
Modes "1152x864" "1024x768" "800x600" "640x480"
EndSubSection
