[Scilab-users] Fwd: Crush using plot in ubuntu + virtual box

[Paul Bignier]

Hello Matias,

It may be driver-related. Try to check your install, notably by making 
tests on your host.

Or maybe you could test a Scilab 5.4.1 to see if it is a Scilab version 
problem.

Hope this helps,
Cordially,
Paul.
