Closing laptop lid breaks the GNOME multi-display configuration
When using a laptop with the GNOME graphical environment that is connected to one or more external displays, closing the lid to suspend the laptop sometimes causes windows and icons to be moved between displays and the display layout to be reset when the system is resumed. To work around this problem, open the GNOME Displays interface, which causes the display configuration to be reloaded. (BZ#1360906)
Limited support for visuals in Xorg
In the Xorg server, only TrueColor and DirectColor visuals at depth 16 or higher are supported for hardware drivers. Legacy applications that need a PseudoColor visual can be run against the Xephyr nested X server, which implements PseudoColor translation when displayed on a TrueColor screen. (BZ#1185690)
