- Option "UseEdidFreqs" "boolean"
This option causes the X server to use the HorizSync
and VertRefresh ranges given in a display device's EDID,
if any. EDID provided range information will override
the HorizSync and VertRefresh ranges specified in the
Monitor section. If a display device does not provide an
EDID, or the EDID doesn't specify an hsync or vrefresh
range, then the X server will default to the HorizSync
and VertRefresh ranges specified in the Monitor section.
EDID is a feature of some displays which allows the display to tell X what its
One of the features that distinguishes various window systems is how they
handle the issue of backing store. When part of a window that was previously
not visible is exposed, there are two basic approaches that a window system
can take. Some keep track of the current contents of all windows and
automatically repair any damage to their visible regions (retained windows).
This saved information is known as the backing store. Others simply report
the damage to the program that created the window and leave repairing the
visible region to the program (non-retained windows).
Note: Using BackingStore "1" (i.e. on) can degrade your X performance - I use
it because it improves the performance of a finite element package I use day
