--- Comment #3 from Chris Wilson <chris at chris-wilson.co.uk> ---
Wait for the hang in matlab. Run "ps ax" to find the matlab process (there may
be more than one, if so repeat until you find something interesting!), then run
"gdb --pid <matlib pid>". Inside gdb, run "bt full", that's the output that
should tell us what's causing the hang.

To get best results out of gdb, requires having the debug symbols for the
packages. Ideally everything used by Matlab, but at least install the symbols
for libxcb* and mesa.
