RHBA-2012:0995 - Bug Fix Advisory

Topic

Updated xorg-x11-drv-intel packages that fix two bugs and add one enhancement
are now available for Red Hat Enterprise Linux 6.

Description

The xorg-x11-drv-intel packages contain an Intel integrated graphics video
driver for the X.Org implementation of the X Window System.

This update fixes the following bugs:

• On Lenovo ThinkPad T500 laptops, the display could have stayed blank after

opening the lid when it was used with an external display in mirror mode.
Consequently, the following message appeared:

Could not switch the monitor configuration
Could not set the configuration for CRT63

With this update, the underlying source code has been modified so that the
display turns on as expected when the lid is open. (BZ#692776)

• On Lenovo ThinkPad series laptops, the system did not always resume from the

suspend state. This was dependent on monitor configuration and could occur under
various circumstances, for example if the laptop was suspended docked with only
external display enabled, and later resumed undocked with no external display.
With this update, the system now resumes correctly regardless of the monitor
configuration. (BZ#711452)

This update also adds the following enhancement:

• In addition, this update adds accelerated rendering support for the Intel Core

i5 and i7 processors. (BZ#821521)

All users of xorg-x11-drv-intel are advised to upgrade to these updated
packages, which fix these bugs and add this enhancement.
