- The Lenovo X220 Tablet Touchscreen is not supported in the kernel shipped with Red Hat Enterprise Linux 6.3.
- The wacomcpl package has been deprecated and has been removed from the package set. The wacomcpl package provided graphical configuration of Wacom tablet settings. This functionality is now integrated into the GNOME Control Center.
- On some tablets, using the NVIDIA Graphics drivers to configure Twinview causes the tablet motions to be incorrectly mapped to the laptop screen instead of the tablet itself. Using the stylus on the tablet moves the cursor on the laptop screen.
- 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.
