Acer Aspire one 751 with Ubuntu and 1366 x 768 resolution

Hi together,

with the follow steps you can install Ubuntu, Xubuntu, Kubuntu and other derivate e.g. Linux Mint with correct resolution of 1366 x 768

First of all you must update you system before you install the graphic driver.

sudo apt-get update

sudo apt-get upgrade

Download the correct key for the sources of the driver

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

Put the follow steps in the sources (maybe with synaptic or edit the file /etc/apt/sources.list)

deb http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main
deb-src http://ppa.launchpad.net/ubuntu-mobile/ppa/ubuntu jaunty main

Update the list.

sudo apt-get update

and install the driver:

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

Reboot the system and the new graphic driver will run.

------------------------


If the system will install a new kernel by the future updates, finish the update and start the system with new kernel.
After them type the follow sentences in a terminal

sudo dkms build -m psb-kernel-source -v 4.41.1

and

sudo dkms install -m psb-kernel-source -v 4.41.1


For a future automatically update create a dkms.conf file.

sudo gedit /etc/dkms/dkms.conf

and fill in the follow sentence

AUTOINSTALL=YES

HAVE FUN!

 

You can dramatically increase the performance of X with a few simple edits to /etc/X11/xorg.conf:

In the device section add the following options (I posted my entire xorg.conf)

Code:

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

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