thanks but i dont know the root password;i never set one. i tried my password and nothing and nothing works.

[aysiu]

There is no root. When you're prompted for a password, it should be your password.

Type
sudo gedit /etc/X11/xorg.conf

What happens?

[crashandburn0420]

it says

Before doing anything else, make sure you back up your xorg.conf file. That way, in case you mess it up, you can replace it with the old file.

To do so, type this in the console:

sudo cp /etc/X11/xorg.conf /etc/X11/xorg.conf_backup

Then, you can retype the command I gave you before.

Okay. See this section?

Section "Monitor"
Identifier "hp mx704"
Option "DPMS"
EndSection

I went to the HP site to find out what your monitor specifications are:

http://h10025.www1.hp.com/ewfrf/wc/d...name=c00039593

So you should add in these two lines to the "Monitor" section:

HorizSync 30-70
VertRefresh 50-140

Now, I'm assuming you really do have the 17" and not the 15". Otherwise, you have to put in the 15" horizontal and vertical synchronization ranges, which are listed in the HP link above.

[crashandburn0420]

should it look like this

Section "Monitor"
Identifier "hp mx704"
Option "DPMS"
HorizSync 30-70
VertRefresh 50-140
EndSection

[aysiu]

Yes.

[crashandburn0420]

it didnt do anything

[aysiu]

So you rebooted and you still didn't get another screen resolution option?
