Power management
There are problems with power management in Gutsy, Hardy, Intrepid and Jaunty. There are work-arounds in each case which involve adding an additional kernel parameter. It can be added by editing the file:
/boot/grub/menu.lst
And adding the appropriate parameter to the end of the line beginning "kernel...
Gutsy
The kernel parameter ec_intr=0 needs to be added. (Provided by the System76 driver?)
Hardy
The kernel parameter acpi=noirq needs to be added. This has the side effect of disabling the screen brightness keys. ( source: Ubuntu Forums )
Intrepid & Jaunty
Timo Tretter has a PPA which provides a patched kernel that fixes the power management issues.
To use it, add these lines to your /etc/apt/sources.list file:
deb http://ppa.launchpad.net/timo-tretter/ppa/ubuntu intrepid main
deb-src http://ppa.launchpad.net/timo-tretter/ppa/ubuntu intrepid main
replacing "intrepid" with "jaunty" depending on your version.
Then, in your terminal, do:
sudo apt-get update
sudo apt-get upgrade
to avoid the error that the server is not signed add the repository key with
sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 0C177666C5D9696595765DC22CC852C735B96A
Karmic
Power management works correctly out of the box.
Lucid
On unplugging the power, gnome power manager reports 2 minutes remaining/98% charged and immediately hibernates.
Current work workaround is to type alt-f2 and run: gconf-editor
Then click apps -> gnome-power-manager -> general -> uncheck use_time_for_policy
This will make gnome-power-manager use the battery charged percentage instead of time remaining for policy actions (source).
Suspend
S3 suspend (suspend to ram) does not work in Hardy, Intrepid, Jaunty, Karmic or Lucid. No fix is available as of June 2010.
BIOS
Latest BIOS Version: 1.30
Adds support for up to 4GB of memory.
Initial BIOS Version: 1.10
Windows Drivers
System76 computers include all of the drivers required for Ubuntu Linux. Windows drivers are available for customers requiring Dual Boot capability.
