Citrix, PnaAuthDialog_popup window solution

If you get a blank window named PnaAuthDialog_popup when running Citrix receiver, the following solved this problem for me:

adding an extra line in /etc/sysctl.conf with:

net.ipv4.tcp_window_scaling=0

...and reboot.

This is taken from the comments at http://joepcremers.com/wordpress/connect-to-citrix-access-gateway-on-ubuntu-9-10/

Trackpoint scrolling

For those that like to use the trackpoint/middle mouse key combo for window scrolling, see http://psung.blogspot.com/2010/09/thinkpad-trackpoint-scrolling-in-ubuntu.html for instructions.

Lotus Notes and Globalmenu

If your menu items under the Actions and Create menus in Lotus Notes have disappeared, blame Unity. Choosing 'Ubuntu Classic' from the login window will re-enable these.

*Update* Workaround: Changing the wrapper script /opt/ibm/lotus/notes/notes-wrapper to...:


#!/bin/sh
cd `dirname "$0"`
export UBUNTU_MENUPROXY=0
LD_PRELOAD=`pwd`/libnotesgtkfix.so `pwd`/notes $*

...will give back the old, "local" menu for Eclipse based applications, in this case Lotus Notes.

See also http://ibmubuntu.blogspot.com/2011/04/lotus-notes-on-natty.html for information on the wrapper script.

Unity icon size

2 quick tips for the Unity dock:

1) to move the icons around, you need to press and hold left mousebutton for a short while.

2) to reduce icon size in the Unity Doc:

- install CCSM through SW Center,

- start CCSM, and search for 'Unity Plugin'

- Select the Experimental pane, and slide the 'Launcher Icon size' to the desired  size:

Globalmenu for Libreoffice

And again, if you want globalmenu  support for Libreoffice install 'lo-menubar' from software center.

WWER

(Update 2, got it, need to deinstall openjdk* packages as well, reflected below)
(Update, this does not work as of now, let me see if I can find a workaround)

As of now, the default Sun Java packages in Natty, will break WWER. You need to downgrade to 6.22.

Make sure the all icedtea-* and openjdk* packages are deinstalled through synaptic.

Go to http://archive.canonical.com/pool/partner/s/sun-java6/

Download (swap with amd64 for those on 64bit):

- sun-java6-bin_6.22-0ubuntu1~10.10_amd64.deb
- sun-java6-jre_6.22-0ubuntu1~10.10_all.deb
- sun-java6-plugin_6.22-0ubuntu1~10.10_amd64.deb

These has to be installed through command line:

Close Synaptic (if open).

sudo dpkg -i sun-java6*

Open Synaptic.


Choose these three packages and choose Package -> Lock Version

Restart firefox.

NB: If you get the 'Downloading WWERS' box, this might fail at about 80%, so you need to redo this until it succeeds and fully downloads. This took me about 10 tries...

Firefox global menu in Unity

If you use Firefox and like the new global menu in Unity, you may want to install 'firefox-globalmenu' from the Software Center, and restart Firefox...

Global Print

To get IBM Global print up and running, make sure you have the following packages installed:


ibm-global-print
ibm-print-emea-ppd
ibm-print-ipselect
ibm-print-us-ppd

ipr-cmd

mpw-engine

mpw-gtk

Use Firefox to install printers from the Global print site.

Missing icons in notification area on Natty

If you, like me, are using Dropbox, the Dropbox Icon will not show up in the Notification area on Natty. To solve this, see http://www.omgubuntu.co.uk/2011/03/how-to-hide-or-show-app-tray-applets-in-ubuntu-11-04/

Short version;

To see the current value type:

gsettings get com.canonical.Unity.Panel systray-whitelist

You should get something like:  ['JavaEmbeddedFrame', 'Wine', 'Skype']

Now, add Dropbox to the list:

gsettings set com.canonical.Unity.Panel systray-whitelist "['JavaEmbeddedFrame', 'Wine', 'Skype', 'Dropbox']"

and at the next login you should see the Dropbox Icon.

Unity

I'm not sure yet how much I like the new Unity interface in Ubuntu Natty, but I'll try to stay with it for a while at least... :) For those who want to get the 'old' gnome GUI back, select 'Ubuntu Classic' from the dropdown at the bottom of the login screen.

Fan noise

To save battery life and get the fan noise down, make sure that:

• 'thinkfan' is installed
• that /etc/default/thinkfan exists and has 'START=yes' in it
• that /etc/modprobe.d/thinkpad_acpi.conf exists and has 'options thinkpad_acpi fan_control=1' in it

Lotus Notes on Natty

You need to fire Lotus Notes with a wrapper to get it up and running properly on Ubuntu Natty.

See...
http://usablesoftware.wordpress.com/2011/04/05/lotus-notes-8-5-2-fp2-in-ubuntu-11-04-natty-narwhal-64bit-beta-1/#comment-168
https://github.com/sgh/lotus-notes_gtk2.23.3

...for more information. You also need to have 'libgtk2.0-dev' installed through apt-get or synaptic to get the make script to run properly.

So, in a terminal (wget's are a single line...):

sudo apt-get install libgtk2.0-dev
mkdir -p /tmp/notesfix
cd /tmp/notesfix


wget --no-check-certificate https://github.com/sgh/lotus-notes_gtk2.23.3/raw/d3492c997bc7a92b895fa1369d4743a8e20b56b5/Makefile


wget --no-check-certificate https://github.com/sgh/lotus-notes_gtk2.23.3/raw/d3492c997bc7a92b895fa1369d4743a8e20b56b5/libnotesgtkfix.c


wget --no-check-certificate https://github.com/sgh/lotus-notes_gtk2.23.3/raw/d3492c997bc7a92b895fa1369d4743a8e20b56b5/notes-wrapper


make
chmod +x notes-wrapper 
sudo cp notes-wrapper libnotesgtkfix.so /opt/ibm/lotus/notes/
sudo gedit /usr/share/applications/LotusNotes8.5.desktop


...where you have to change the line
Exec=/opt/ibm/lotus/notes/framework/../notes %F
with
Exec=/opt/ibm/lotus/notes/framework/../notes-wrapper %F

32 bit or 64 bit Natty

I have earlier tried both 64bit and 32bit distributions of Ubuntu for running IBM workstation SW, and have found that with a 32bit PAE kernel I get the best results. This is on newer thinkpads that have the appropriate processor flags for running (if you need it) 64bit VMWare/Virtualbox guests. Internal IBM print and java are examples that have been giving me problems on 64bit Ubuntu.
