Time to wake up.

I just came across Gitso on Google Code.

I haven’t tried it yet but it is rather interesting in that it allows reverse VNC connections ie: A client requiring assistances fires up Gitso on their machine and ‘requests’ help from their support service via VNC.

As stated by the project page, this would greatly simplify the process of getting someone connected to offer them support via VNC.

Here is another one of my ‘reminder-to-self’ fixes for my Ubuntu 8.04 machines.

I’ve installed Hardy on a good few machines now including Intel C2D/Nvidia chipset desktops and various laptops and discovered that, to my delight, the machines will go in and out of S3 suspend (suspend to ram) in just a few seconds.

There was just one problem which seemed universal though; the USB ports were not reinitializing correctly. It seemed that although the +5v power was coming back, they weren’t being polled for devices or data.

I stumbled across a partial solution by typing lsusb (in an attempt to poll connected devices). Sure enough, the USB data communication came back to life and I was able to use my devices as normal. Obviously, all I needed now was a way to make this happen automatically when the machine comes back out of S3.

User aidave on this post at ubuntuforums came up with a quick bit of hackery to make this happen which I have adapted here:

Fire up a terminal and issue:

cd /usr/lib/pm-utils/sleep.d
sudo touch 98usb
sudo chmod +x 98usb
sudo nano 98usb

You should now have a blank file open in nano (in the console)

Cut and paste the following into nano:

#!/bin/sh

case “$1″ in
resume|thaw)
lsusb
;;
*)
;;
esac

It doesn’t fix the issue directly but it qulifies as a work around in that it wakes up the usb ports by polling the with the lsusb command as the machine resumes from ACPI S3 suspend.

Hopefully there will be a proper fix for the issue in a future Ubuntu Hardy patch.
