RHBA-2013:0478 - Bug Fix Advisory

Topic

Updated tigervnc packages that fix two bugs and add one enhancement are now
available for Red Hat Enterprise Linux 6.

Description

Virtual Network Computing (VNC) is a remote display system which allows you to
view a computing 'desktop' environment not only on the machine where it is
running, but from anywhere on the Internet and from a wide variety of machine
architectures. This package contains a client which will allow you to connect to
other desktops running a VNC server.

This update fixes the following bugs:

• When the Xvnc server was started by the vncserver init script, but no password

file existed, the initscript failed without displaying a message. This bug is
now fixed and the "VNC password for user is not configured" message appears when
the password is not configured for the Xvnc session. (BZ#688624)

• Previously, the user was not allowed to change the value of the

AcceptPointerEvents parameter while Xvnc was running. As a consequence, when the
"vncconfig -set AcceptPointerEvents=1" command was used to enable and "vncconfig

• set AcceptPointerEvents=0", to disable mouse input for VNC session, it failed

with an error message, similar to the following:

Setting param AcceptPointerEvents=0 failed

Now the user is allowed to change the value of the AcceptPointerEvents parameter
and the mouse input for a VNC session can be enabled or disabled while Xvnc is
running. (BZ#843714)

In addition, this update adds the following enhancement:

• The tigervnc packages have been updated to match the latest X server version.

(BZ#844486)

Users of tigervnc are advised to upgrade to these updated packages, which fix
these bugs and add this enhancement.
