I just recently switched from Mandriva 2006 to Ubuntu (by the way, how is that pronounced?), and I'm lovering it! Finally, a fast/simple distro where ACPI actually works. Anyways, my computer is an acer laptop with a wide screen at 1280 x 960, but the closest fitting res in System/Preferences/Screen Resolution menu is 1024 x 760. Does anyone know how I could change my res to 1280 x 960? Thanks for your help.

ok, I did the xorg reconfigure thing twice, and it diden't work. I made sure to select the resolution I want, but instead of adding that to the list after I rebooted, the only extra entry is 960 x 600, which of course looks terrable on this screen. Any idea what I might be doing wrong?

P.S. Below is the contents of my xorg.conf file. Perhaps it will be usefull.
You could try generating your own modeline with the "gft" program.
Code:
gtf 1280 960 56 -x
This output a line with a modeline for "1280x960_56.00". Remove the ".00" and either insert the modeline in your [Monitor] section. This is what I had to do to get 1280x800 on my laptop when I used SuSE 9.3.
Also, read through your /var/log/xorg.0.log file. It's possible that there was a problem setting up a screen for the 1280x960 resolution. The two lines:
HorizSync 30-60
VertRefresh 50-75
can be a bit touchy if the values are off.

I ran the gtf program in the terminal, and here is the responce.
If I'm understanding you correctly, I'm supposed to instert the modeline somewhere in the monitor section of my xorg.conf. However, I'm a bit fuzzy as to exactly where to put it (I know how picky config file syntax can be). Also, in responce to IsaacKuo, the book that came with the laptop listed it's max resolution as 1280 x 960. Perhaps its not widescreen, but that is what I thought of it as, sence it looks a little wider than you average 15" screen.

First of all, the "xorg.conf" file has its own man page.
Yes, there are two ways of doing it. One way is to have a Modes section and use "UseModes" in the Monitor section.
The other is to use the "ModeLine" identifier, which your generated modeline has. Then in the Screen section, change the "1280x960" to "1280x960_56" so that they match your modeline entry. For example:
Depth 24
Modes "1280x960" "1024x768" "800x600" "640x480"
I'm not certain but I think you should change your modeline to:
Modeline "1280x960_56" 94.22 1280 1352 1488 1696 960 961 964 992 -HSync +Vsync
Some distros will produce a modes section. That makes it possible to have one section shared between two Monitor sections. Please back up your old xorg.conf file before changing it.
You might consider copying your monitor section and changing the identifier on your old one. It is the MonitorID listed in the ServerLayout section that determines which one is used.
If you were the experimental type, you could use the second dual head output, add a usb keyboard and another mouse, and set things up so that two people can operate your computer independently.
Then both your kids can be doing their homework at the same time!
I tried adding that modline you posted, but it didn't work (I probably didn't do it right). When I rebooted my laptop, xorg wouldn't start. It is a good thing that I know how to use the command line a bit, because I used it to remove the edited xorg.config and replace it with a backup file. So now I'm back up in the gui, and right back where I started.
Over the weekend I got the idea, to do the xorg config thing from the command line, as posted earlier by pljvaldez:
Code:
sudo dpkg-reconfigure xserver-xorg
However, when I did it this time, I only selected my desired resolution in the resolution mode selection part, and none of the others. When I rebooted my computer, my screen was configured exactly how I want it. Thanks to everyone who gave advice on how to solve this problem.

Is this really possible? I would like to try it if it is.

how'd u do that? I went all the way through the point where I choose what resolutions to add. im stuck as to how to enable the resolution i want.
I could be wrong, but I think the key to how I solved the problem was to make sure that only one resolution is selected when going through the setup. When you did the setup, did use select multiple resolutions, or just one?
