Dell Inspiron 9100 - How Get 1280X800 Display Going

Hello All,

Great to be joining the growing ran of Ubuntu users, and this community.

I have Ubuntu Breezy Badger running on my Dell Inspiron 9100. While I haven't put it thru many tests, all is great... very easy installation.

Getting wireless running was a bit of a bear, but I got that done, via help of these forums (reading posts). I have tried to do the same regarding my resolution, but have not been able to make any progress.

The Inpriron I am using has an ATI Mobility Radeon 9700 card, and will run up to 1280 X 800 under windows. I did the default Ubuntu installation, and the result is that I have video, but I believe (I am in Windows now posting this) it is maxed out at 1024 X 768.

Beening a newbie, I have crashed out my Ubuntu installation several times (I don't know what I am doing), trying different things in the forums... I can't do that again, so I wanted to see if someone could take me by the hand and lead me thru making this happen. I don't game. I am a business user mainly, and a programmer in (self) traiining. I am just looking at setting my resolution at 1280X800).

Thank you in advance for any help you can provide.

I have tried several things, such as going into my xorg.conf file as changing the

Can you post your xorg.conf file? It's most likely that you need to set the resolution and/or modelines.

Hello and thank you for the prompt response. :)

Here is my xorg.conf file, which was located here: /etc/x11/xorg.conf

Thank you very, very much for your help.

Hello all... I fell like a dumb dumb... I attached my xorg.conf file, but it wouldnt take it (inappropriate file type). How can I get it attached?

Thank you.

You should copy and paste the contents of the file in a Pastebin.

I have a Dell Inspiron 9100 as well, but I ordered one with the ATi Radeon 9800 and the WUXGA screen. Ubuntu easily and automatically recognized that my maximum resolution is 1920x1200.

Omeg,

Hope you are digging your Dell, esp. with Ubuntu on it. I am, even at lower resolution than I would like. Wireless can be a pain, so drop me a line if you need help with that. I can point you in the right direction on the forums. :)

Thank you for your help. I just posted my xorg.conf file using the pastebin under the name mindundermatter.

Have a good one.

Folks,

I goofed again.... my original post should have said - Dell Inspiron 9100 - How to Get 1920X1200 Display Going.

1920X1200 (which is what I use under Windows) is what I am shooting for... sorry for any confusion.

Folks,

As an update to this post, I ran thru the process listed here: http://ubuntuforums.org/showpost.php?p=423584, but still cannot get this done.

I am to the point of begging for assistance on this.

Thank you.

Ok, you need to put the resolution(s) you want in your xorg.conf. So, you should change it to read like this:

# /etc/X11/xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.
#
# Edit this file with caution, and see the /etc/X11/xorg.conf manual page.
# (Type "man /etc/X11/xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

You may need to experiment with the Modeline a bit, but you shouldn't need to. I've got 1680x1050 going fine without and I've run higher without too, so that should do it for you.

Blueplazma,

Thank you for your help with this. I replaced the contents of my xorg.conf file with your contents. Also, I tried modifying the modeline (you will see that below) with the resolution of 1920X1200, but no dice.

Here is what my xorg.conf file now looks like:

/etc/X11/xorg.conf (xorg X Window System server configuration file)

#

This file was generated by dexconf, the Debian X Configuration tool, using

values from the debconf database.

#

Edit this file with caution, and see the /etc/X11/xorg.conf manual page.

(Type "man /etc/X11/xorg.conf" at the shell prompt.)

#

This file is automatically updated on xserver-xorg package upgrades *only*

if it has not been modified since the last upgrade of the xserver-xorg

package.

If you have edited this file but would like it to be automatically updated

again, run the following command:

sudo dpkg-reconfigure -phigh xserver-xorg

Sorry about not pasting this in the window - in a separate section like you did - but couldn't figure out how to do that.

Not sure what is going wrong here... maybe I am doing some wrong wrong in the sequence of actions I am taking. I can tell you exactly what I did, if that will help. Please just let me know.

Thank you very, very much for your help.
