<p dir="ltr">Dear Tim!</p>
<p dir="ltr">For me it seems that you need to use proprietary AMD drivers - fglrx.<br>
Open drivers are buggy and show low-performance.</p>
<p dir="ltr">If you want to use open driver on Ubuntu 12.04 LTS (precise) you should upgrade its HWE to 14.04 LTS (trusty).</p>

with the report below. It's only happened with Scilab, but it appears<br>
to be the video driver that's complaining, so I don't know if this is a<br>
problem with Linux or with Scilab. The processor is an AMD A10 with<br>
on-board video processing which is considerably different from my<br>
12-year-old Dell that this computer is replacing.<br>

Does anyone have clues for the clueless? Particularly suggestions for<br>
isolating, fixing, or working around the problem?<br>
