I just tried starting IDL on a colleague's laptop running AcceleratedX
V4.1 in 16 bpp mode. It refused to run IDL in PseudoColor (8-bit) mode,
and started in TrueColor mode instead (I verified this using 'device,
get_visual_name=name' to check it wasn't in DirectColor mode). The
commands

device, decomp=0, retain=2
loadct, 0
tvscl, dist(256)

gave a strange rainbow of colors, which did not change when I clicked on
the graphics window. I'm going to have to investigate this further, but
it looks like starting the Linux X server with either

startx -- -bpp 8

or

startx -- -bpp 24

is required for reliable IDL operation under Linux. If anyone knows
otherwise, please let me know.

Cheers,
Liam.
