[Scilab-users] New computer, graphics(?) crashes

[Tim Wescott]

I just installed Xubuntu, 14.04, 64 bit.  Even without the fglrx
drivers, it's faster and it doesn't seem to crash (at least, it's 570
seconds into a simulation, with tons of updates to the monitor graph,
without problem).

Thank you all.
