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

[tim at wescottdesign.com]

For what it's worth, in Lubuntu the full fglrx packages causes immediate 
crashes, while uninstalling all fgrlx-related stuff except for 
fgrlx-core makes it last a while before it dies.

Also, this computer was a rush job to replace my rather old previous 
machine which died Monday morning, and all I did to "install" the OS was 
to use the old hard drive.  As a consequence, the new machine is running 
in 32-bit mode, not 64.  I'm not sure how mature the 64-bit stuff is, or 
how neglected the 32-bit stuff may be at this point.
