Drivers are available in the gma500 PPA repository for Maverick, Lucid, Karmic, Jaunty and Intrepid. With the note that Jaunty and Intrepid versions are no longer supported and guaranteed to work.
Open a terminal and type:
sudo add-apt-repository ppa:gma500/ppa && sudo apt-get update && sudo apt-get install poulsbo-driver-3d
reboot for the changes to take effect.
Note: remember to perform after a version upgrade the commands in the terminal again to update to the gma500 packages matching your Ubuntu version.
You can also choose from alternative drivers to the PSB drivers, all having different advantages and disadvantages over the others. These drivers are: fbdev, iegd and emgd.
For instructions on using fbdev (or plain Vesa) with 1366x768 resolution, see .
In general the PSB drivers mentioned on this very page are best supported in performance, compatibility and features.
The gma500 PPA repository also ships mplayer, gnome-mplayer and vlc (currently vlc has still some issues and does not always work) with enabled vaapi backend. These are only available for Maverick and Lucid. They can be installed with the package manager of your choice.
An unofficial Lucid iso image with gma500 support and mplayer-vaapi already embedded is available for downloading over bittorrent.
There is an error with the psb package on the ISO. Kernel upgrades are broken. Please perform commands entered below to fix this issue. Not performing these commands can render your system unable to boot in case of kernel upgrades or Ubuntu version upgrades.
sudo apt-get update sudo apt-get purge psb-kernel-source sudo apt-get upgrade sudo apt-get install psb-kernel-source sudo apt-get install poulsbo-driver-2d poulsbo-driver-3d poulsbo-config
When applying any tweaks from below we kindly request you to provide feedback concerning the results from the chosen tweaks on your laptop. Please fill out to send your findings to the gma500 team.
Known tweaks and workarounds for Karmic and Lucid (installed by default for Maverick and Natty)
sudo mv /usr/lib/pm-utils/sleep.d/99video /usr/lib/pm-utils/99video
sudo apt-get purge vbetool && sudo apt-get install uswsusp
and suspend using:
sudo s2ram --force
to make this permanent, run:
sudo gedit /etc/pm/config.d/00sleep_module
and set in the file:
SLEEP_MODULE="uswsusp"
and run:
sudo gedit /etc/pm/config/defaults
and add in the file:
S2RAM_OPTS="--force" QUIRK_NONE="true"
sudo gedit /etc/default/grub
add the following parameters to grub configuration:
GRUB_CMDLINE_LINUX="acpi_osi=Linux acpi_backlight=vendor"
next run:
sudo update-grub
sudo gedit /etc/X11/xorg.conf
and add the following option:
Option "ExaNoComposite" "true"
* install this updated poulsbo-config package:
* install compiz
You can often improve peformance by limiting the amount of RAM used by the system so that there will be more available for the videocard:
sudo gedit /etc/default/grub
add the following parameters to grub configuation if you have for example 1GB RAM:
GRUB_CMDLINE_LINUX="mem=896mb"
or if you have 2GB RAM:
GRUB_CMDLINE_LINUX="mem=1920mb"
next run:
sudo update-grub
echo "psb drm_psb" | sudo tee -a /etc/initramfs-tools/modules && sudo update-initramfs -u
In Maverick you would also have to remove "no_fb=1" from /etc/modprobe.d/poulsbo.conf
(for all Ubuntu releases):
* install gnome-mplayer and gecko-mediaplayer
* tune gnome-mplayer settings like the following screenshots:
(This should already be automatically done by the gnome-mplayer package from the gma500 repository)
* install this firefox addons: http://flvideoreplacer-extension.blogspot.com/
The Poulsbo hardware is not supported in the community version of Ubuntu. However, it is reputed to "just work" on Hardy version shipped by a netbook manufacturer.
For example, the support for GMA 500 hardware by Dell Ubuntu Hardy 8.04 is provided by the following repository
deb hardy-dell-mini public
The Ubuntu community is a great example of free software community in action, and is arguable one of the greatest examples of free software community in the world. To make Ubuntu better, You would like to take a look on new project and provide any help.
Double check that the psb kernel module can be loaded into the running kernel by running modprobe psb. If not, remove and re-install the psb module as mentioned under Installation CD with psp drivers.
This is a known bug with psb kernel driver. Due to partial close nature of the driver, because Intel has not released an open source driver, the bug fix is currently no available. There are reports that a new driver will be available shortly.

If you're still having problems, please mail , and do not submit bug reports.
