[Scilab-users] Cannot start Scilab 6.1.1

[Stefan Du Rietz]

When I did that, this message did not appear at startup in the Scilab 
command window:

"at line    56 of function xmlGetValues ( 
/usr/local/scilab/scilab-6.1.1/share/scilab/modules/xml/macros/xmlGetValues.sci 
line 69 )
at line    22 of function help         ( 
/usr/local/scilab/scilab-6.1.1/share/scilab/modules/helptools/macros/help.sci 
line 34 )

xmlGetValues: Invalid XPath request."

However, the messages in the terminal remained, seemingly (from the 
content) because of the nVidia graphics driver.

After changing to "X.Org X server -- Noveau display driver from 
xserver-xorg-video-nouveau (open source)" they did not appear.

So, *with the nVidia driver*, if I start Scilab from a .desktop-file 
with JAVA_OPTIONS..., then no error messages are visible and the 
graphics seem to work.

Is there any possible disadvantage?

Regards
Stefan
