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.<div><div><br>

Dear guys!<br>
<br>
I'll test Scilab on AMD A4-4000 today with Ubuntu 12.04.5 LTS and<br>
14.04.2 LTS and report back.<br>
<br>
On my laptops I successfully use Scilab 5.x on Intel HD graphics (open<br>
drivers) and old Nvidia (GTX6xx, GT425, 9600GT both with proprietary<br>
drivers).<br>

<br>
Yep, first thing to do.<br>
And keep on digging on the videocard driver side if you still have<br>
troubles.<br>
Scilab tends to be a good way to detect buggy video drivers!<br>
Getting a cheap videocard with decent drivers might be the easiest<br>
way to solve your problem.<br>
You might try to ask other Linux users what card they have and<br>
whether they get graphics related crashes.<br>
