Overview

With Ubuntu Jaunty 9.04, most everything is working out of the box, but some tweaks are needed for an optimal performance:

Sound

This option has to be added at the end of the /etc/modprobe.d/alsa-base.conf file:

• options snd-hda-intel model=dell-m6

Graphic card (Intel Graphics Media Accelerator (GMA) 4500MHD)

Out of the box, the graphic card is working, but not so well (fuzzy rendering, some slowness with Compiz, etc.). To make it work perfectly, advanced drivers from X Updates PPA repository must be used, using Synaptic. See this page: https://launchpad.net/~ubuntu-x-swat/+archive/x-updates

These advanced drivers will probably be integrated in future Ubuntu versions, so it will then work perfectly out of of the box.

Suspend to ram (sleep) & buttons for Brightness & CD/DVD Eject

Out of the box, multimedia and other special buttons are working, except for brightness and CD/DVD eject. Sleep is not working at all. To correct all this, the noapic option should be added to the defoptions section in /boot/grub/menu.lst, like in the following:

# defoptions=quiet splash noapic

Once done, the following command must me issued:

sudo update-grub

Everything should work after reboot.

PC speaker

PC speaker "beep" is on by default, which is annoying. To get rid of it, the following line must be added to /etc/modprobe.d/blacklist.conf:

blacklist pcspkr

PC Speaker should be off after reboot.
