screen resolution issue

What XP does or doesn't do is completely irrelevant.

Can you give the output of:

sudo lshw -C display

Thanks.

Hi,

You may want to have a look at the following forum threads: http://ubuntuforums.org/showthread.php?t=732401

try:

gksudo gedit /etc/X11/xorg.conf

add this code:

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

Section "Monitor"
    Identifier "Configured Monitor"
    VendorName "Unknown"
    ModelName "Unknown"
    HorizSync 28.0 - 33.0
    VertRefresh 43.0 - 72.0
    Option "DPMS"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
    SubSection "Display"
        Depth 24
    EndSubSection
EndSection

Save the new file and close gedit then reboot. This should then be ok, if you get no display then boot to root recovery root console and rename xorg.conf

You can also try this code:

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

Section "Monitor"
    Identifier "Configured Monitor"
    VendorName "Unknown"
    ModelName "Unknown"
    HorizSync 28.0 - 33.0
    VertRefresh 43.0 - 72.0
    Option "DPMS"
EndSection

Section "Screen"
Identifier "Default Screen"
Monitor "Configured Monitor"
Device "Configured Video Device"
DefaultDepth 24
    SubSection "Display"
        Depth 24
 Modes "1024x768"
    EndSubSection
EndSection

There is only the extra line difference, you can change 1024x768 to whatever you prefer (make sure your display can output the resolution).
