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.

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...
