Synopsis

xorg-x11-drv-mga bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

Topic

An updated xorg-x11-drv-mga package that fixes two bugs and adds one enhancement is now available for Red Hat Enterprise Linux 5.

Description

The xorg-x11-drv-mga provides the Matrox video driver for the X Window System.

This update fixes the following bugs:

  • Previously, the X Window System selected an incorrect monitor resolution if Extended Display Identification Data (EDID) could not be read (for example, when the monitor was unplugged on boot). As a consequence, the graphical screen was distorted. This was caused by a faulty mode selection heuristic for Matrox G200e chips. This update fixes the problem and the correct monitor resolution is now selected even if EDID is not available. (BZ#735713)

  • Due to a bug in the mga driver, a shift could occur in the video screen on future Dell systems with Matrox G200eR2 chips. The screen output was corrupted, and windows and text were pushed around randomly. This update optimizes priority request control, and the screen is no longer corrupted on the aforementioned systems. (BZ#745089)

In addition, this update adds the following enhancement:

  • This update adds support for screen resolution of 1920x1200 on ServerEngines Pilot 3 (Kronos 3) chips. (BZ#475269)

All users of xorg-x11-drv-mga are advised to upgrade to this updated package, which fixes these bugs and adds this enhancement.
