RHBA-2013:0344 - Bug Fix Advisory

Topic

Updated mesa packages that fix several bugs and add various enhancements are now
available for Red Hat Enterprise Linux 6.

Description

Mesa provides a 3D graphics API that is compatible with Open Graphics Library
(OpenGL). It also provides hardware-accelerated drivers for many popular
graphics chips.

The mesa packages have been upgraded to upstream version 9.0, which provides a
number of bug fixes and enhancements over the previous version. (BZ#835200)

This update also fixes the following bugs:

• If the user logged in from Red Hat Enterprise Linux 5 to a Red Hat Enterprise

Linux 6 machine by using the "ssh" command with the "-Y" option, an attempt to
run an application that uses GLX failed with the "Error: couldn't find RGB GLX
visual or fbconfig" error message. This bug has been fixed and the remote login
now works as expected. (BZ#786508, BZ#820746)

• Due to an error in the mesa packages, using the multisample anti-aliasing

(MSAA) technique with the KWin window manager caused errors in the desktop
compositing. This update provides a patch that fixes this bug and MSAA now works
correctly with the KWin window manager. (BZ#885882)

• Previously, when connecting to a remote machine using SSH with the X11

forwarding enabled caused a "failed to load driver: i965" error in the libGL
library. With this update, a patch has been provided to fix this bug and drivers
are now loaded as expected. (BZ#901627)

In addition, this update adds the following enhancements:

• An accelerated driver for Intel Core i5 and i7 processors has been added to

the mesa packages. (BZ#816661)

• This update adds the new mesa-dril-drivers package to mesa. This package

implements support for the DRI1 drivers. (BZ#835201)

All users of mesa are advised to upgrade to these updated packages, which fix
these bugs and add these enhancements.
