Installing or updating packages signed with a GPG key not known or accessible to the system may throw PackageKit in a loop of password dialogues, repeatedly asking the user to confirm the installation of these packages from an untrusted source.

This issue may occur if additional third party repositories are configured on the system for which the GPG public key is not imported into the RPM database, nor specified in the respective Yum repository configuration. Official Red Hat Enterprise Linux repositories and packages should not be affected by this issue.

To work around this issue, import the respective GPG public key into the RPM database by executing the following command as root:

~]# rpm --import <file_containing_the_public_key>

After resuming the system or re-enabling the display, an icon may appear in the notification area with a tooltip that reads:

Session active, not inhibited, screen idle. If you see this test, your display server is broken and you should notify your distributor. Please see http://blogs.gnome.org/hughsie/2009/08/17/gnome-power-manager-and-blanking-removal-of-bodges/ for more information.

This error message is incorrect, has no effect on the system, and can be safely ignored.

Running a AMD64 system without the sssd-client.i686 package installed, which uses SSSD for getting information about users, causes acroread to fail to start. To work around this issue, manually install the sssd-client.i686 package.

With newer kernels, such as the kernel shipped in Red Hat Enterprise Linux 6.1, Nouveau has corrected the Transition Minimized Differential Signaling (TMDS) bandwidth limits for pre-G80 nVidia chipsets. Consequently, the resolution auto-detected by X for some monitors may differ from that used in Red Hat Enterprise Linux 6.0.

When enabled, fingerprint authentication is the default authentication method to unlock a workstation, even if the fingerprint reader device is not accessible. However, after a 30 second wait, password authentication will become available.

Evolution's IMAP backend only refreshes folder contents under the following circumstances: when the user switches into or out of a folder, when the auto-refresh period expires, or when the user manually refreshes a folder (that is, using the menu item Folder Refresh). Consequently, when replying to a message in the Sent folder, the new message does not immediately appear in the Sent folder. To see the message, force a refresh using one of the methods describe above.

The clock applet in the GNOME panel has a default location of Boston, USA. Additional locations are added via the applet's preferences dialog. Additionally, to change the default location, left-click the applet, hover over the desired location in the Locations section, and click the Set... button that appears.

In some multi-monitor configurations (for example, dual monitors with both rotated), the cursor confinement code produces incorrect results. For example, the cursor may be permitted to disappear off the screen when it should not, or be prevented from entering some areas where it should be allowed to go. Currently, the only workaround for this issue is to disable monitor rotation.
