Corruption has again been reported on Intel hardware running Xorg with the modesetting driver (which uses OpenGL based acceleration instead of SNA acceleration the intel driver defaults to). Reported in various forms on Sandy Bridge (X220), Ivy Bridge (X230) and Haswell (X240). Confirmed to not occur with the intel driver but the xserver was changed to default to the modesetting driver on >= gen4 hardware (except Ironlake). One means of triggering this is to open a large pdf with xpdf on an idle machine and highlight a section of the document. There have been reports of gpu hangs on gen4 intel hardware (T500 with GM45, X61 with 965GM) when starting Xorg as well.

<h1>Disclaimer</h1>

|
|
<p>
|
|
Mesa is a 3-D graphics library with an API which is very similar to
|
|
that of <a href="http://www.opengl.org/">OpenGL</a>.*
|
|
To the extent that Mesa utilizes the OpenGL command syntax or state
|
|
machine, it is being used with authorization from <a
|
|
href="http://www.sgi.com/">Silicon Graphics,
|
|
Inc.</a>(SGI). However, the author does not possess an OpenGL license
|
|
from SGI, and makes no claim that Mesa is in any way a compatible
|
|
replacement for OpenGL or associated with SGI. Those who want a
|
|
licensed implementation of OpenGL should contact a licensed
|
|
vendor.
|
|
</p>
|
|
|
|
<p>
|
|
Please do not refer to the library as <em>MesaGL</em> (for legal
|
|
reasons). It's just <em>Mesa</em> or <em>The Mesa 3-D graphics
|
|
library</em>. <br>
