Installed software#

gpsbabel#

To allow the USB devices to be read and written by a non-privileged user, create a file called /etc/udev/rules.d/51-garmin.rules with the following contents: 
SYSFS{idVendor}=="091e", SYSFS{idProduct}=="0003", MODE="666"

Improvements#

Things that have improved with this release:

HP 6830s specifics#

My latest laptop requires some extra tweaks :

Sound#

Add the following line to /etc/modprobe.d/alsa-base.conf: 

options snd-hda-intel model=laptop enable=1 index=0

Video driver#

Install the native ATI/AMD video driver if you want 3D effects. If you don't need that, the default driver is fine too.

Wireless driver#

This one works magnificently out of the box:

fan control#

First disable the BIOS option "Fan Always on while on AC Power".

But after that you still see the fan going on fairly loud at 47 degrees Celsius and turning off at 42 (if the environment is not too warm). To change this behavior you can patch the dsdt tables:

Patching DSDT tables

The following resources were helpful:

I followed the following procedure (mainly as described in the first link above): 

mkdir dsdt
cd dsdt
cp /proc/acpi/dsdt .
# disassemble it
iasl -d dsdt
# save the original
cp dsdt.dsl dsdt-orig.dsl
# now first edit the dsdt.dsl file (see below) and then recompile:
iasl -tc dsdt.dsl
#
# update initial ramdisk
#
cp dsdt.aml /etc/initramfs-tools/DSDT.aml
VERSION=`uname -r`
update-initramfs -u -k $VERSION
#
#  then reboot

DSDT Patch

These numbers are hexadecimal and seem to indicate the percentage of fanspeed, so 0x64 is 100% fan speed. I don't know if temperature thresholds are included, I don't think so.

Font settings#

Thanks to http://blog.xam.dk/archives/81-Making-Eclipse-look-good-on-Linux.html 

After they are installed I ran gnome-font-properties and used the following settings:

Application/Document/Desktop font: Liberation Sans, size 8
Window title font: Liberation Sans Bold, size 10
Fixed with font: Liberation Mono, 10

Font rendering: Best contrast (the others left weird artifacts, but mostly up to taste here I think)

Under details:
Resolution: 99 dpi (to avoid the letters to get too close, need at least 1 px between them 
Smoothing: Grayscale

Hinting: Full 

Depending on your Eclipse font settings the above will be enough, 
but if you already have tweaked some settings remember to check your Font settings under Eclipse preferences 
and verify that you are actually using the System default or the Liberated fonts to get the smoother more compact look.
