How to set screen resolution on Dell laptop


I'm running Ubuntu Intrepid on Dell Inspirion laptop.
I can't get the screen resolution set.
The highest available in System -> Screen Resolution is 1024 X 768.
I used 915 resolution in the past, but for some reason that's no longer available.
How can I set the screen resolution? Lost here, for sure.
Thank you.

lspci | grep -i vga

cat /etc/X11/xorg.conf | grep -i driver
cat /var/log/Xorg.0.log | grep autoconfigured

00:02.0 VGA compatible controller: Intel Corporation Mobile 915GM/GMS/910GML Express Graphics Controller (rev 03)

Previously, I was able to set it with 915resolution from Synaptics Pkg Mgr. But for some reason that is no longer available.

The highest available from System -> Screen Resolution is 1024 X 768 which is quite awful. With 915 resolution I was able to get a very nice display.

Can't edit xorg.conf because it's no longer used.

In a way, it gets harder and harder to use linux on a laptop. Frustrating and confusing.

thank you

You didn't do the last command that would have showed the driver Xorg is using...
cat /var/log/Xorg.0.log | grep autoconfigured

No you don't want to download 915 resolution it's been replaced by the intel driver and xrandr.
I'm trying to figure out if you have the intel driver installed or not..


if it's not installed..
sudo apt-get install xserver-xorg-video-intel


additiona changes to settings and resolutions should be able to be made using Xorg RandR

I get this:

rich@rich-laptop:~$ cat /var/log/Xorg.0.log | grep autoconfigured
(==) Matched intel for the autoconfigured driver
rich@rich-laptop:~$

OK so you are running the new Intel Driver.

There is no xorg.conf in Ubuntu. It now uses HAL.

You just need to create the xorg.conf file if it's not present. it will used it once created.

http://tuxtraining.com/2009/05/08/xo...904-and-others

Code:
X -configure
mv ~/xorg.conf.new /etc/X11/xorg.conf

Please go slow with me.

If I do what you last instructed, it will create an xorg.conf file?

Then what do I do???

With the highest resolution available with the intel driver, it makes the dialog box so HUGE, that even if there were other options available, I can not reach the "Apply" button with the cursor and I can't move the box any more.

I need to do it from a terminal.
