RHBA-2009:1373 - Bug Fix Advisory

Topic

Updated xorg-x11-server packages that fix bugs and add enhancements are now
available.

Description

X.org X11 is an open source implementation of the X Window System. It
provides the basic low level functionality upon which full fledged
graphical user interfaces such as GNOME and KDE are designed.

These updated packages address the following bugs:

• an error in trapezoid rasterisation that caused X to crash and which

could be triggered on large web pages has been fixed. (BZ#448586)

• a crash in software image transfers on 64-bit systems that caused Xvfb

(the X virtual framebuffer) to segfault has been fixed. (BZ#467370)

• a 64-bit bug in the x86 emulator that prevented X from starting on AMD64

and Intel 64 clients was corrected. (BZ#503072)

• the xorg-x11-server-randr-source package is obsolete but no other

packages "obsolete" it. With this update xorg-x11-server obsoletes the
randr-source package and, if the old package is present, installing this
update will remove it automatically. (BZ#503072)

This update also includes the following enhancements:

• the -maxclients command line option was added to the X server. This

option allows for configurations with either more clients or more resources
per client. (BZ#439797)

• two new opcodes to support newer video BIOSes were added. Note: Intel

Mobile Express Series 5 chipsets (also known as "Ironlake graphics" for the
CPU used with the chipsets) are only supported in VESA mode in Red Hat
Enterprise Linux 5. (BZ#503182)

All xorg-x11-server users should upgrade to these updated packages, which
resolve these issues and add these features.
