RHBA-2015:1301 - Bug Fix Advisory

Topic

Updated libdrm, mesa, xorg-x11-drv-ati, and xorg-x11-drv-intel packages that fix
several bugs and add various enhancements are now available for Red Hat
Enterprise Linux 6.

Description

The libdrm packages comprise a runtime library for the Direct Rendering Manager.
Mesa provides a 3D graphics API that is compatible with Open Graphics Library
(OpenGL) and hardware-accelerated drivers for many popular graphics chips. The
xorg-x11-drv-ati packages include a driver for ATI graphics cards for the X.Org
implementation of the X Window System. The xorg-x11-drv-intel packages contain
an Intel integrated graphics video driver for the X.Org implementation of the X
Window System.

• The libdrm packages have been upgraded to upstream version 2.4.59, which

provides a number of bug fixes and enhancements over the previous version.
(BZ#1186821)

• The mesa packages have been upgraded to upstream version 10.4.3, which

provides a number of bug fixes and enhancements over the previous version. Among
other changes, this version includes support for new Intel 3D graphic chip sets.
(BZ#1032663)

• Support for new Intel 3D graphic chip sets has been backported to the

xorg-x11-drv-intel packages.

• The xorg-x11-drv-ati packages have been upgraded to upstream version 7.5.99,

which contains a number of bug fixes and enhancements over the previous version.
Among other changes, this version includes support for new AMD 3D graphic chip
sets. (BZ#1176666)

This update also fixes the following bug:

• Previously, the radeon driver did not work correctly with the Virtual Network

Computing (VNC) module if hardware acceleration was enabled. Consequently, a VNC
client connected to a computer set up this way only displayed a blank screen.
With this update, this problem has been resolved, and it is now possible to use
VNC with the aforementioned setup. (BZ#1084104)

Users of libdrm, mesa, xorg-x11-drv-ati, and xorg-x11-drv-intel are advised to
upgrade to these updated packages, which fix these bugs and add these
enhancements.
