Some Ubuntu-related tricks will be descibed here.

X

If X gets totally hosed (i.e. you don't have any graphical interface at all), try running "sudo dpkg-reconfigure xserver-xorg" and select a very basic video configuration, using the "vesa" video driver, and accepting all the default options.

Matlab

Matlab R2007a crashes frequently in Ubuntu Feisty. Apparently most of these problems are actually the fault of Java, on which Matlab relies heavily. By setting a few environment variables and upgrading the java JVM, most of these quirks can be fixed.

Install a new JVM by typing:

sudo aptitude install sun-java6-jre sun-java6-fonts

Now set the MATLAB_JAVA environment variable to point to the new JVM. I start Matlab via the following shell script (which I put in ~/bin):

export AWT_TOOLKIT=MToolkit
export MATLAB_JAVA=/usr/lib/jvm/java-6-sun-1.6.0.00/jre
eval `~/ligotools/bin/use_ligotools`
/usr/local/bin/matlab $*
