How do I enable backing store on my XFree86 or Xorg X11 Server?
By default XFree86 3.3.x has backing store enabled while XFree86 4.x.x does not. You can determine if backing store is currently enabled on your X Server by running “baudline -sysinfo”. If the value of backing store is NotUseful, then for maximum baudline performance you should add the following backing store line to your /etc/X11/XF86Config or /etc/X11/xorg.conf file and then restart your X11 Server. Here is an example snippet: Section “Device” Identifier “ATI Rage LT PRO” VendorName “Unknown” BoardName “Unknown” Driver “ati” Option “DPMS” Option “backingstore” EndSection For more information on backing store read about baudline’s -backingstore command line option.
