1.229. xorg-x11-server

1.229.1. RHBA-2009:1691: bug fix update


This update has already been released (prior to the GA of this release) as errata RHBA-2009:1691
Updated xorg-x11-server packages that resolve an issue are now available. X11 is an open source implementation of the X Window System. It provides the basic low level functionality upon which full fledged graphical user interfaces such as GNOME and KDE are designed.
These updated xorg-x11-server packages fix the following bug:
* when using a dual-head X11 configuration with more than one display, if the user's session was locked by gnome-screensaver, then clicking or typing only resulted in a black screen and a mouse pointer instead of a login prompt as expected. Because of this, it was not possible to log back in to the desktop session once gnome-screensaver had been started. This update restores the ability to log back into a session after gnome-screensaver has started when using a dual-head X11 configuration. (BZ#537759)
All users of xorg-x11-server are advised to upgrade to these updated packages, which resolve this issue.

1.229.2. RHBA-2010:0259: bug fix update

Updated xorg-x11-server packages that fix various bugs are now available.
X.Org X11 is an open source implementation of the X Window System. It provides the basic low level functionality upon which graphical user interfaces such as GNOME and KDE are designed.
These updated packages address the following bugs:
* resizing a glxgears window horizontally across the screen caused X to segfault. Changes were made in the related mesa packages and resizing no longer causes the error. (BZ#435963)
Note: due to the unusual build process for this package, the code fix is applied to the mesa packages, but the resulting compiled code is in the xorg-x11-server package (see BZ#536868 for the bug as raised against mesa).
* the X server ceased support for Pluggable Authentication Modules (PAM). Support for PAM was added back to the package and PAM can now be used as expected. (BZ#486120)
* a patch had been added to the xorg-x11-server package which was going to cause compatibility issues between the xorg-x11-server package and proposed NVIDIA drivers. The randr-disabled-fb.patch was removed and the package should now work as expected. (BZ#496108)
* the MGA and Xserver drivers were defaulting to inappropriate resolutions, causing the screen to go black, or be otherwise unreadable. The default values were changed, and resolution is now set to more reasonable values. (BZ#507536 and BZ#497853)
* when using multiple outputs on some ATI hardware, the GNOME screensaver and some related functions were not operating correctly. Changes were made to the xorg-x11-server package to better support the gnome-screensaver and xinerama functions and the screensaver now works correctly. (BZ#516204,
* changing to a higher resolution on Radeon 3100 hardware caused unexpected results on the desktop image. The X server resizing code was fixed to also resize the screen pixmap, and changing resolutions now works as expected. (BZ#515609)
* the Anaconda graphical installer failed to start at the default 800x600 resolution on systems utilizing Intel Graphics Device Next Generation (IGDNG) devices. Support for this device has now been added, and Anaconda now starts correctly. (BZ#510120)
* the X server did not automatically detect the QXL virtual graphics device, causing unexpected behavior with mouse detection and movement. The QXL driver is now loaded correctly and the mouse problems no longer manifest. (BZ#558611)
Users are advised to upgrade to these updated xorg-x11-server packages, which resolve these issues.
