Aspire ONE (Model 0751H) GMA500 widescreen display setup on Fedora 14

Before installation of the problematic Poulsbo driver on Ferdora 14 (freshly installed), please try the followings first:

$ su -c 'yum clean all'
$ su -c 'yum update'

Reboot to let the updated kernel running.

Install rpmfusion free and non-free repositories rpms:

$ su -c 'yum localinstall --nogpgcheck \
http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-stable.noarch.rpm \
http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-stable.noarch.rpm'

Thanks to AdamW's articles, the correct steps are listed here:

To install Poulsbo driver:

$ su -c 'yum –enablerepo=rpmfusion-nonfree-updates-testing \
install xorg-x11-drv-psb'

To fix the problem of missing psb.ko for whatever updated kernel:

$ su -c'yum –enablerepo=rpmfusion-nonfree-updates-testing \
install akmod-psb'

Reboot to take effect for widescreen display.

Optimize the following sections in /etc/X11/xorg.conf:

Section "Device"
Identifier  "Videocard0"
Driver      "psb"
Option      "IgnoreACPI"
Option      "MigrationHeuristic" "greedy"
Option      "ShadowFB" "true"
EndSection

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

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

Section "DRI"
Mode 0666
EndSection

Edit /etc/grub.conf as follows:

Add the following parameters to the end of line of kernel command:

elevator=noop mem=896m acpi_osi=Linux acpi_backlight=vendor

Reboot and see if the system performance is improved.
