Getting Citrix Receiver to work

using the latest version of the  citrix receiver.  http://www.citrix.com/lang/English/lp/lp_2309126.asp?ntref=DLpromo1

download the .deb client.   Let it install using defaults (it will ask for root).

For firefox run: sudo cp /usr/share/ca-certificates/mozilla/*.* /opt/Citrix/ICAClient/keystore/cacerts/

now to try  chromium

Moving from 10.10 to 11.10 was a major step backwards in terms of my dual head setup.  Today I am going to try to rectify this problem.

First to identify my hardware and driver level.

lspci | grep VGA

01:00.0 VGA compatible controller: nVidia Corporation G96 [GeForce 9500 GT] (rev a1)

and now the driver level. 

I am going to use this site to help me through the issue http://us.download.nvidia.com/XFree86/Linux-x86/285.05.09/README/index.html

Downloaded the latest nVidia driver for my card ~/Downloads/NVIDIA-Linux-x86_64-290.10.run

As a note here, to get into text mode on Oneric 11.10, I needed to get to the grub boot menu and append "text" to the end of the boot line.   No way to get to init 3 from the current version.  It seems to be a known bug.  

once I downloaded the latest driver for linux 64bit from the nvidia site (www.nvidia.com).  I was able to install from text mode by running


NVIDIA-Linux-x86_64-290.10.run

and running nvidia-settings

how to quickly tell what version of ubuntu

Here is a quick command to find out what version of Ubuntu you are running:

cat /etc/issue

Install and configure openssh-server

First install and configure the openssh server ... run the following commands

sudo apt-get install openssh-server

sudo cp /etc/ssh/sshd_config ~

Edit the ssh configuration file to disallow root logins.

sudo gedit /etc/ssh/sshd_config

PermitRootLogin no

The next thing I like to setup is to setup logins without having to type in the password from other computers on the network.

generate an RSA key for the client computer (in this case my laptop)

ssh-keygen -t rsa

make a directory on the server you are trying to connect to:

ssh nallison@grote-ubuntu mkdir -p .ssh

put the key on the server you are trying to connect to:

cat .ssh/id_rsa.pub | ssh nallison@grote-ubuntu 'cat >> .ssh/authorized_keys'

updated to the nvidia drivers

updated the drivers to use my nvidia geforce 9500 -- by the way I have had lots of problems with the latest distros ... (FED 16) as well and my geforce 9500 trying to do dual monitors. I am using the twinview configuration for my X desktop, but I am not pleased with it. I will devote a thorough post to this later on ...

this is my current driver setting ...

and my current /etc/X11/xorg.conf

install restricted extras

Install ‘Ubuntu Restricted Extras’ – codecs/plugins

You need to install the audio mp3 (MPEG Layer 3) decoders as it’s required for playing your mp3 songs), similarly you need to install Adobe flash player on Ubuntu 11.10 for playing flash content such as YouTube Videos (although they are trying to replace the flash dependencies with HTML 5). You can install all these proprietary plugins/codecs by installing the package called ‘ubuntu restricted extras’. Open a terminal and execute the command -

sudo apt-get install ubuntu-restricted-extras

Restricted library/packages for playing encrypted DVD’s

Although you’ve installed ‘ubuntu-restricted-extra’, you still won’t be able to play any proprietary DVD (which is usually encrypted with CSS(Content Scramble System) ). Therefore You also need to install libdvdcss2, a free software library for unscrambling/accessing those DVDs. Open terminal and execute the following commands (You may need to reboot) -

sudo apt-get install libdvdread4 sudo /usr/share/doc/libdvdread4/install-css.sh

Updating to the latest versions of installed software

Next thing to do .... update ubuntu

sudo apt-get update
sudo apt-get upgrade

# alternatively ... start update manager
