Matlab on Linux, no toolbar displayed, problem solved

I had Matlab R2007a installed on my computer, running Ubuntu 8.04 Beta. But matlab can't display the toolbar, nor can the Matlab editor show up correctly. A solution can be found at: http://www.mathworks.fr/matlabcentral/newsreader/view_thread/152223

If you are running Matlab on Linux, and with Compiz installed. You should add up one line in bash before running Matlab.

$ export AWT_TOOLKIT=MToolkit ; matlab

Step 2: You need to apply a patch to ns-2.27 to make it works with gcc4.1. You can get the patch here
To apply the patch, type patch -p0 <ns-2.27-gcc410.patch in bash

Step 3 : Download LEACH code, extract it under ~ns-2.27/ directory.

mit/rca/energy.o mit/rca/rcagent.o \
mit/rca/rca-ll.o mit/rca/resource.o \
mac/mac-sensor-timers.o mac/mac-sensor.o mit/uAMPS/bsagent.o \
Step 5.2 : Add the environmental variables to /etc/profile
export RCA_LIBRARY=$NS_HOME/ns-2.27/mit/rca
export uAMPS_LIBRARY=$NS_HOME/ns-2.27/mit/uAMPS
Step 5.3: source /etc/profile and clean up previous build
source /etc/profile
make clean
Step 5.4: Rebuild ns2, redirecting output
nohup make 2>error.log >make.log &

Step 6: Test default wireless demo and LEACH
./test

Step 7: Validate the full installation, redirect the output
nohup ./validate-full 2> validate.error >validate.log &

DONE, Enjoy!

Adding new partition in /etc/fstab with UUID

If you want to add a new partition in /etc/fstab under file system you no longer have /dev/xxx but an UUID (Unique unit ID).

To find out the UUID of your partition just use the following command:
sudo vol_id -u <device>

for example, if you want to find the UUID of /dev/sda6, using the command:
sudo vol_id -u /dev/sda6

The rest is then as in the past.
