Ubuntu

I have an Acer Aspire One with 1366x768 res. It runs on Ubuntu at 1024x768 with no option.

Asked by Joe M. Cummings

The problem is that I have no option for setting the resolution of the screen except 1024x768. The native res. of the Acer Aspire One is 1366x768. I will need detail instructions. Thank you, Joe

As copied from https://help.ubuntu.com/community/AspireOne (which you may find useful for other things, too):
(Please note that I have modified this slightly for your convenience)

Enabling 1366x768 Resolution on AspireOne 751h (11.6")

With this variant (popular because it's available at Costco), the maximum graphics resolution (1366x768) does not work out of the box. To install an updated graphics driver, run the following commands in the terminal:

sudo sh -c 'echo "deb http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main">/etc/apt/sources.list.d/graphicsdriver.list

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys C6598A30

sudo apt-get update

sudo apt-get install xserver-xorg-video-psb psb-kernel-source

sudo shutdown -r now

Post install performance is a bit sluggish and can be fixed with a small edit to /etc/X11/xorg.conf. Open the file for editing (alt+f2 then enter "gksu gedit /etc/X11/xorg.conf") and add these lines (under the "Device" section)(up to the third "EndSection"):

Section "Device"
        Identifier "Videocard0"
        Driver "psb"
        Option "IgnoreACPI"
        Option "AccelMethod" "exa"
        Option "MigrationHeuristic" "greedy"
        Option "NoDDC"
EndSection

Section "Extensions"
        Option "Composite" "Enable"
EndSection

Section "Screen"
        Identifier "screen1"
        Device "Videocard0"
        DefaultColorDepth 24

        Subsection "Display"
                Depth 24
                Virtual 1366 768
        EndSubsection

        Subsection "Display"
                Depth 16
                Virtual 1366 768
        EndSubsection

        Subsection "Display"
                Depth 15
                Virtual 1366 768
        EndSubsection

        Subsection "Display"
                Depth 8
                Virtual 1366 768
        EndSubsection
EndSection

Restart X (log off and back in).

I am sure this did solve the problem. I am sorry to take so much time to respond, as the solution came to me very quickly. I was out of town. I doubt I will implement this solution, as I believe it would require it be redone each time there was a significant upgrade. It is a little complex even apart from that problem. Please know I do appreciate your help but I am just not wanting to learn much about the inner workings of linux as long as I do not have to, and I am most pleased up to now I have not had to. I love linux, and I thank you for your quick response. IBM gave the industry a wonderful gift in the PC a few years ago; as it spurred an industry with people writing software and building cards in their garage, to do everything one might want to do with their PC (answer their telephone, etc). When microsoft gained monopoly control, they took all that away from the industry. Added to that problem is the fact it has always been such a poor O.S., it has been sad to watch. I hope linux can break their strangle hold on the industry. It has been so sad to see our industry loose so much growth over the years because of the monopoly abuse of microsoft. I only just want to use my computer as a tool, to do the work I need to do, and I want to convey my appreciation to you and others for supporting this product.
