Here is the answer guys, on how to do it without changing the effects:
1) Open a terminal o press ALT+F2, then run/type: gconf-editor
2) Go to /desktop/gnome/remote_access and enable “disable_xdamage”

some launchpad bugs for this issue:

https://bugs.launchpad.net/ubuntu/+source/vino/+bug/299112

https://bugs.launchpad.net/ubuntu/+source/vino/+bug/772873

related ubuntu forum posts:

http://ubuntuforums.org/showthread.php?t=1744161

Please note: This workaround does NOT appear to work on the new ubuntu 11.10. There is no “disable_xdamage” in the remote_access keys:

No disable_xdamage key available for 11.10

[root@localhost ~]# ping -c2 www.google.com
ping: unknown host www.google.com

Edit /etc/resolv.conf to add some nameservers:

# Googles Public DNS
nameserver 8.8.8.8
nameserver 8.8.4.4
search localdomain

No reboot necessary!

(writing this basic step because Googling does not provide simple answer. ) This is not obviously how to set up a DNS server – it is just how to get the box to resolve DNS. old school basics that no one seems to want to document.

1. On apt based Linux, install wkhtmltopdf and its dependencies :
sudo apt-get install wkhtmltopdf

2. Usage:

To convert a remote HTML file to PDF:
wkhtmltopdf http://www.google.com google.pdf

To convert a local HTML file to PDF:
wkhtmltopdf my.html my.pdf

You can also convert to PS files if you like:
wkhtmltopdf my.html my.ps

Creator/maintainer has also recently created some PHP bindings for this as well. More on this version at http://blog.perplexedlabs.com/2010/09/15/convert-html-to-pdf-in-php-libwkhtmltox-extension/

sudo apt-get install mt-daapd
will get you a nice reliable music server. Available in Ubuntu repositories.

>mt-daapd -V
Firefly Media Server: Version svn-1696

You can configure from the web interface:

If you must manually configure a setting, /etc/mt-daapd.conf can be manually edited.

g@gubuntu:~$ sudo more /etc/mt-daapd.conf

Firefly Media Server is being re-written (forked-daapd)

Note: Adding these software repositories to your ubuntu installation can have undesired effects if you leave them in the sources.list after their initial use.

The mt-daapd media server has been forked by the last contributor Julien Blache, and is being totally re-written. See http://blog.technologeek.org/2009/06/12/217 and http://blog.technologeek.org/2011/04/09/483

The latest debian build http://alioth.debian.org/~jblache/forked-daapd/

One way to install forked-daapd on an Ubuntu system from http://jamesdanylik.com/articles/undoing-the-damage-replacing-mt-daapd-firefly-with-forked-daapd/

Basically, it includes adding “deb http://ftp.debian.org/debian squeeze main” to your /etc/apt/sources.list, running an “apt-get update,” and then using the Debian testing build of forked-daapd to install with a “sudo apt-get install forked-daapd.” Very clever, and makes the whole process pretty painless.

One caveat: if you’re like me and Jason, you’ll probably get an error saying “main: libgcrypt version mismatch” when forked-daapd tries to start up. This is due to Debian using a different version of gcrypt; install it with “sudo apt-get install libgcrypt11,” and you should be right as rain. Just don’t forget to delete the Debian line from your sources.list after you get everything working, or you’ll have all sorts of strange problems. Edit your setting in /etc/forked-daapd.conf, and start the party by running “sudo /etc/init.d/forked-daapd start.

Key Server Error fix from

http://en.kioskea.net/faq/809-debian-apt-get-no-pubkey-gpg-error

Issue

When updating the Debian based system, it may happens that the apt-get displays an error message like:

W: GPG error: ftp://ftp.debian.org/ testing Release:

The following signatures couldn’t be verified because the public key is not available: NO_PUBKEY 010908312D230C5F

W: There is no public key available for the following key IDs:

010908312D230C5F

This is a new feature of the apt-get system that guarantee the authenticity of servers for updating Debian.

Solution

Type the following commands, REPLACE the number of the key that displayed in the error message:

gpg –keyserver pgpkeys.mit.edu –recv-key 010908312D230C5F

gpg -a –export 010908312D230C5F | sudo apt-key add -

..but instead to manufacture a very low cost PC that can be given to kids for free and courses built up around their use. When we say low cost, we mean so low even the OLPC would be impressed.

Braben has developed a tiny USB stick PC that has a HDMI port in one end and a USB port on the other. You plug it into a HDMI socket and then connect a keyboard via the USB port giving you a fully functioning machine running a version of Linux. The cost? $25.

The hardware being offered is no slouch either. It uses a 700MHz ARM11 processor coupled with 128MB of RAM and runs OpenGL ES 2.0 allowing for decent graphics performance with 1080p output confirmed. Storage is catered for by an SD card slot. It also looks as though modules can be attached such as the 12MP camera seen in the image above.

We can expect it to run a range of Linux distributions, but it looks like Ubuntu may be the distro it ships with. That means it will handle web browsing, run office applications, and give the user a fully functional computer to play with as soon as it’s plugged in. All that and it can be carried in your pocket or on a key chain.

tiny, tiny computer
