RHBA-2011:0756 - Bug Fix Advisory

Topic

An updated xorg-x11-drv-qxl package that fixes various bugs is now available.

Description

xorg-x11-qxl-drv is an X11 video driver for the QEMU QXL video
accelerator. This driver makes it possible to use Red Hat Enterprise
Linux 6 as a guest operating system under KVM and QEMU, using the SPICE
protocol.

This updated package includes support for rev. 02 devices with
surfaces. (BZ#670009)

This update also fixes the following bugs:

• When using the qxl driver, resolution choices inside the guest

would not exceed 1024x768 in size unless the xorg.conf configuration
file was created and manually edited. This update ensures that larger
resolutions are now available for guests with appropriate hardware
without requiring a manual change to the xorg.conf file. (BZ#623652)

• When using the qxl driver, when connected to a virtual guest using

SPICE and logging into a desktop session from the GDM display manager,
switching to a virtual console using a key combination caused a server
crash, and GDM to respawn. This update fixes this issue so that in the
aforementioned situation, switching to a virtual console and back to
the graphical desktop now works as expected. (BZ#626508)

• Xorg crashed shortly after X started up. This was caused by an

insufficient amount of video memory made available to the qxl device.
This update fixes this by making additional memory available to Xorg
so that it no longer crashes. (BZ#680120)

• Running the Xorg command with the configure parameter (Xorg
• configure) using the qxl driver resulted in a blacked out console

window. This update provides a fix so that Xorg no longer crashed when
run with the -configure parameter. (BZ#680865)

• The description field against the X.Org X11 qxl video driver was

non-descriptive and stated only the name of the driver. This is now
fixed to include descriptive information about the video driver.
(BZ#684994)

Users are advised to upgrade to this updated xorg-x11-drv-qxl package.
