Manual unpacking 5.5.1 to /usr/local may cause missed system dependencies. On my ubuntu I have many scilab versions - 5.3.3 from repository and newer versions (unpacked to ~/Software with custom launchers on desktop).</p>

<br>
I can change the problems that I get, but basically I start Scilab and<br>
get:<br>
<br>
libEGL warning: Could not open<br>

At this point I try to open a graph (plot2d(1:10)), the graph window<br>
opens, and Scilab freezes.<br>
