Ubuntu 64 bits notes

I had to install an SAP 2007 ISA central instance on my workstation and that requires a 64 bit OS

So it was time to install Ubuntu hardy heron 64 bits, 64 bits is good but there are a few quirks, i list here all the quirks and tips i had to find to make it behave.

Smooth fonts

See:

http://www.howtogeek.com/howto/ubuntu/enable-smooth-fonts-on-ubuntu-linux/

gedit ~/.fonts.conf

<?xml version="1.0&#8243; ?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<fontconfig>
<match target="font">
<edit name="autohint" mode="assign">
<bool>true</bool>

</fontconfig>

Flash 9 in firefox

See:

http://ubuntuforums.org/showthread.php?t=772490

sudo apt-get install nspluginwrapper flashplugin-nonfree lib32nss-mdns
sudo ln -sf /usr/lib/nspluginwrapper/plugins/npwrapper.libflashplayer.so /usr/lib/firefox-addons/plugins/
sudo ln -sf /usr/lib/nspluginwrapper/plugins/npwrapper.libflashplayer.so /usr/lib/firefox-3.0/plugins/

Java webstart and plugin in firefox

See:

http://dmartin.org/content/running-java-web-start-apps-ubuntu-linux-amd-64

sudo apt-get install ia32-sun-java5-bin
#use that to run .jnlp files

this does not seem to work with all .jnlp files (or maybe it’s SAP specific).

NVidia video drivers

See:

https://help.ubuntu.com/community/BinaryDriverHowto/Nvidia
See:

https://help.ubuntu.com/community/FixVideoResolutionHowto

Close all opened apps cause otherwise it might go wrong

sudo apt-get install envyng-gtk

start Envyng (Applications menu)
Then choose nvidia -> automatic install
reboot or at least restart Xwindows.

Run nvidia-settings (menu or sudo nvidia-settings)

Go to x server display config and choose whatever you want (resolution & refresh rate) ex: 1280*1024 @ 75Hz
and then press "save to x config. file"
and restart X again (Ex: XTRL-ALT-BACKSPACE)

Ubuntu screen resolution chooser will still say 50Hz, you can ignore that, it’s not.

Blank java applications windows

Compiz is a cool eye candy window manager add-on for gnome, unfortunately there is a bug and when it's enabled, java applications just show a bank empty useless window.

I need Netbeans and other java apps to work, so i need to disable compiz:
Go to system-preference-appearance-visual effects: and Select ’None’

After doing this however you won't have any transparency at all, and won't be able to use cool things like avant-window-manager (Apple like dock for Linux), so we enable a lightweight transparency manager which does not have the java issue:

sudo apt-get install xcompmgr

Start it manually for now: xcompmgr &

We need it to start automatically when X starts
Go to preferences -> sessions -> startup programs
Add: name:compmgr command:/usr/bin/xcompmgr

====Advance window manager (awn) (OSX like dock for Linux)=====
I like a nice dock like thing, here is how i installed it:

you need a composition manager for this to work, see above topic for installing xcompmgr

See:

http://news.softpedia.com/news/Install-AWN-on-Hardy-Heron-82611.shtml
Add apt sources:

gedit /etc/apt/sources.list

deb http://ppa.launchpad.net/awn-testing/ubuntu hardy main
deb-src http://ppa.launchpad.net/awn-testing/ubuntu hardy main

Install it:

sudo apt-get update
sudo apt-get install awn-manager-trunk awn-extras-applets-trunk

Start it:
Applications -> Accessories -> Avant Window Navigator or just avant-window-navigator &

Run the awn manager: awn-manager and in the general tab select: "Automatically start AWN on login"

Removing gnome panel:
Right now you will have both gnome menu bars and the dock which is lame, after you had the useful stuff to your dock, you will want to disable gnome-panel:
You will want to kill it killall gnome-panel , and probably also preventing it from running next time:
See: Preferences -> sessions ...

SAP Gui

Sapgui (platin) only works right using java 32 bits since it needs to call 32 bits libraries (JNI), so created a wrapper like this:

sapgui.sh

export PLATIN_JAVA=/usr/lib/jvm/ia32-java-1.5.0-sun/bin/java
../SAPClients/SAPGUI/bin/guilogon

Getlibs to make 32 bits programs start

To install or upgrade:
http://www.boundlesssupremacy.com/Ca...etlibs-all.deb
Download and double click the file to install.

To install a 32-bit debain package for a program (not a library!) use
Code:

sudo dpkg -i --force-all package_name.deb

Then use: Ex: sudo getlibs /usr/bin/skype
