Chapter 1. Package Updates

• Lenovo Thinkpad notebooks have a "Fn" key that can be combined with the numbered function keys
to access a variety of features, typically including volume, screen brightness, sleep, and switching
to an external monitor. Previously, these key combinations would not produce the desired outcomes
on X61 Thinkpad notebooks. Although some of these functions were enabled by changes in other
software components, no support existed within the graphics drivers for the key combinations that
would brighten and dim the display. Support for these features is now present in the driver. X61
users can now use the hotkeys to control screen brightness on their notebooks. (

• previously, although the code to support HDMI output was included in the driver, this was not
initialized while the system detected displays. Therefore, the system was unable to detect monitors
connected by DVI. HDMI detection is now enabled so that when the system initializes displays, the
system can detect monitors on DVI connections and output to them correctly. (

• previously, Xinerama mode was not enabled for the "intel" driver. Therefore, when users set
Xinerama mode for a graphics card that uses the "intel" driver, the driver would crash. The "intel"
driver now includes support for Xinerama, making this mode available to users. Note that a scrolling
problem that users also experienced when using the "intel" driver for dual-head configurations was
not related to this driver, and is resolved in a separate update for the X server. (

All users of the xorg-x11-drv-i810 driver should upgrade to this updated package, which resolves
these issues and adds these enhancements.
1.246. xorg-x11-drv-mga
1.246.1. RHBA-2009:1390: bug fix update
An updated xorg-x11-drv-mga driver which fixes several bugs is now available.
xorg-x11-drv-mga is a video driver for the X.Org implementation of the X Window System, for Matrox
G-series chips.
This updated package provide the following bug fixes:
• the driver version written to the Xorg log file in /var/log/ did not reliably match the driver version
in use. (The Xorg log file reported version 1.4.1 when the version in use was 1.4.2.) With this
update, this error has been corrected and the Xorg log file reports the driver version accurately.

• some video cards based on the Matrox G200SE chip-set do not have enough installed RAM to
support 24-bits per pixel (bpp) at 1024 x 768 pixels resolution. Previously, the xorg-x11-drv-mga
driver automatically switched output to 16-bpp when a display being driven by such a card was
running at 1024 x 768 (XGA) pixels resolution regardless of the amount of installed RAM. With this
update, only cards with 2 MB of RAM or less are automatically switched to 16-bpp. Matrox G200SE-
based video cards with more installed RAM can now display 24-bpp at 1024 x 768. (

)
• the limited bandwidth of the G200SE chip-set caused some 24-bit color modes to be rejected
when using the default 32-bpp framebuffer. With this update, a 24-bpp packed framebuffer is now
the default for G200SE-based cards. This reduces the bandwidth required and allows otherwise
rejected modes to work. Note: the 32-bpp framebuffer is still the default for other chip-sets.

All xorg-x11-drv-mga users should upgrade to this updated package which addresses these issues.
