RHBA-2007:0756 - Bug Fix Advisory

Topic

Updated xorg-x11 packages that fix various bugs and add an enhancement are
now available.

Description

X.org is an open source implementation of the X Window System providing
basic low-level functionality that full-fledged desktop environments such as
GNOME and KDE are built on top of.

These updated packages fix the following bugs:

• The X Font Server (xfs) daemon used 100% CPU if the xorg-x11-xfs package

was installed without the fonts-xorg-base package.

• It was not possible to switch to the "French Canadian (Basic)" keyboard

layout in the GNOME keyboard preferences because adding the "French
Canadian (Basic)" keyboard layout failed to change the current keyboard layout.

• Rotating the screen using xrandr in the K Desktop Environment (KDE)

caused incorrect panel placement.

• The keyboard LED status lights for capslock and numlock were not consistent

when switching between X and a Virtual Terminal (VT).

• Previous xorg-x11 packages had a MAXCLIENTS value of 256, meaning

that more than 256 connections to an X server caused an error. This value
has been raised to 512 maximum connections.

• Some external displays ignored DDC probing, causing graphic cards

using the ATI Radeon driver to default to a safe resolution of 640x480 for
external displays such as a projector. The default resolution for these types
of displays has been raised to 800x600.

• On Itanium architectures the cirrus driver was disabled, which broke X for

Hardware Virtual Machine (HVM) guests. The cirrus driver is now enabled for
these guests.

This update also adds the following enhancements:

• Support for the Radeon RS480 series chipsets.
• Support for the XGA Volari Z9s GA controller.

All xorg-x11 users should upgrade to these updated packages, which resolve
these issues and add this enhancement.e
