Acer Aspire Timeline 4810T laptop and Backlight Control, part 2.

I have GREAT news for the 4810T owners the 2.30 BIOS[1], we now have backlight control keys working

There is a catch after you upgrade[2] 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

Setting up NTP to update from a GPS

This is just a quick how to to setup NTP to update from a GPS

Second question ask you to were tthe GPS is connected, in my case it was /dev/ttyUSB0

LINK: UNetbootin

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. :-)
