I have GREAT news for the 4810T owners the 2.30 BIOS, we now have backlight control keys working
There is a catch after you upgrade to the 2.30 BIOS you will get a freeze type effect on the desktop (well I did). Also I noticed that my WiFi went funny to and I could not ping anything even tho Net. Mgr. was say I was connected to AP.
So DON’T play with backlight key till done the below changes.
You have to change from
xrandr –output LVDS –set BACKLIGHT_CONTROL native
xrandr –output LVDS –set BACKLIGHT_CONTROL kernel
xrandr –output LVDS –set BACKLIGHT_CONTROL combination

This is just a quick how to to setup NTP to update from a GPS
Installing software needed for the GPS:
# apt-get install gpsd
If you already not done so connect the GPS to your computer you are wanting to run it on and confirm it is connected with lsusb
Bus 001 Device 003: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port
My GPS is a USGlobalSat BU 353
Now to configure gpsd:
# dpkg-reconfigure gpsd
There just a few questions to answer.
First question asks you if you like to have gpsd to start at boot, I answered YES
Second question ask you to were tthe GPS is connected, in my case it was /dev/ttyUSB0
The last 2 questions I just left them as is.
UNetbootin allows you to create bootable Live USB drives for a variety of Linux distributions from Windows or Linux, without requiring you to burn a CD. You can either let it download one of the many distributions supported out-of-the-box for you, or supply your own Linux .iso file if you’ve already downloaded one or your preferred distribution isn’t on the list.
I found this UNetbootin very useful to put FreeDOS on my USB flash drive to use to update the BIOS on my laptop. UNetbootin is also in the Debian repository too.
