Chapter 34. Desktop

The pygobject3-devel.i686 32-bit package has been removed in Red Hat Enterprise Linux 7.2 and was replaced with a multilib version. If you have the 32-bit version of the package installed on a Red Hat Enterprise Linux 7.1 system, then you will encounter a yum error when attempting to upgrade to Red Hat Enterprise Linux 7.2.

To work around this problem, use the yum remove pygobject3-devel.i686 command as root to uninstall the 32-bit version of the package before upgrading your system.

The binutils package earlier than version 2.23.52.0.1-54 causes a segmentation fault during the build. As a consequence, it is not possible to build the Emacs text editor on IBM Power Systems. To work around this problem, install the latest binutils.

In the GNOME desktop environment, with some laptops, external displays connected to a docking station might not be automatically activated when resuming a suspended laptop after it has been undocked and docked again.

To work around this problem, open the Displays configuration panel or run the xrandr command in a terminal. This makes the external displays available again.

On the ARM architecture, the Emacs text editor sometimes terminates unexpectedly with a segmentation fault when scrolling up a file buffer. This happens only when the syntax highlighting is enabled. There is not currently any known workaround for this problem.
