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>Mesa 7.5.2 Release Notes, 28 September 2009</h1>
|
|
|
|
<p>
|
|
Mesa 7.5.2 is a bug-fix release fixing issues found since the 7.5.1 release.
|
|
</p>
|
|
<p>
|
|
The main new feature of Mesa 7.5.x is the
|
|
<a href="http://wiki.freedesktop.org/wiki/Software/gallium">Gallium3D</a> infrastructure.
|
|
</p>
|
|
<p>
|
|
Mesa 7.5.2 implements the OpenGL 2.1 API, but the version reported by
|
|
glGetString(GL_VERSION) depends on the particular driver being used.
|
|
Some drivers don't support all the features required in OpenGL 2.1.
|
|
</p>
|
|
<p>
|
|
See the <a href="../install.html">Compiling/Installing page</a> for prerequisites
|
|
for DRI hardware acceleration.
