I have an HP 900-350 workstation, and have been playing with
some color programs in the last couple of days. The monitor
(HP 98782A) has 8 planes (as reported by xdpyinfo), but
for some reason its colormap only has 64 colors (equivalent to 6 planes).
I need the 256 of an 8 plane display for the pictures I have to look good.
Is there a way to change the default colormap size for
the server?
Thanks,
/Luis

I suspect that xdpyinfo is reporting back incorrect information. :-( If memory
servers me correctly the MIT R3 HP server had this problem. Are you using
this or an HP released server? The monitor you mentioned is a 19" 1024x768
color montior (HP 98782A). Assuming you do not have an SRX 3D graphics card,
you either have a 98547A 6 plane graphics board or a 98549A High Res,
High Performance 6 plane Color graphics board.
As you probably know this translates into 64 colors unless you wish to produce
clients that ask the window manager for their own colormaps. This is generally
bad form as it causes the rest of the windows to look *very ugly* when these
clients have the focus, but may be useful when you just have to have those
colors.
All current HP 1280x1024 displays have at least 8 planes.
Hope that this helps.
