    You have probably entered new .Xdefaults - but let's fix your
system files instead of the .Xdefaults.

The .Xdefaults controls whether shared memory is used and whether
8-bit pseudo color or 24-bit true color is used.  The former is very
desirable for speed reasonsw.  The latter allows more functionality
but is slower (in 24 bit).  If you change the file /etc/system
(requires root privilege and a reboot of the computer) by adding the
lines 

* Large shared memory segment for AIPS TV, from Dave Brown
*   GEM, 20 Mar 98

set shmsys:shminfo_shmmax=8388608

then you can enable or disable the XAS options and it will still
work.  (The solaris default max shared memory is a mere 1 Megabyte.)
