OK, after some digging I figured out that the video card on the Sun-Ultras
here is set to 8+24 depth (that is 8 __and__ 24 bit) -- in other words its
24-bit enabled, but is capable of showing 8-bit only applications (in case
those applications check, I guess).
Here's the video command and the output,
$ pgxconfig -prconf
--- Hardware Configuration for /dev/fbs/gfxp0 ---
Type: GFX8P
Board: TSI Raptor GFX 8P
PROM Information: 1.11 99/07/06 TSI
DAC: TSI RAMDAC 0x31
RAM: 8MB
EDID Data: 1024x768x85, 800x600x85, 640x480x85, 1152x864x85,
1600x1200x85, 1600x1200x75, 1800x1440x75, 640x480x60, 640x480x75,
800x600x60, 800x600x75, 1024x768x60, 1024x768x75, 1280x1024x75
Current resolution setting: 1280x1024x75
Possible depths: 8, 24, 8+24
Current depth: 8+24
and
$ pgxconfig -propt
--- OpenWindows Configuration for /dev/fbs/gfxp0 ---
OWconfig: system
Video Mode: none
Depth: 24
OK, does 24-bit really work, well I did the following,
xv -24 -best -perfect -cmap -cgeom -0-0 kittens.jpg
And in the "XV Controls" window it notes using "24-bit mode. Using TrueColor
visual" meaning the solaris Xserver (Xsun) is capable of 24-bit. So I asked
a sys-admin friend and he noted that "xdpyinfo is probably unable to
understand 8+24 mode and is simply returning the first result it sees when
multiple options are available." So I'm not sure how fvwm determines what
the X-server is capable of, but its figuring them to be 8-bit on this
machine when they really need to be 24-bit (is it grabbing xdpyinfo's
output ?). Anything I can do to make fvwm resolve to 24-bit short of
restarting the server with that depth setting explicitly (meaning I'd
have to call the powers that be to change the configuration on this
machine - after a million+1 questions) ? What do other window managers
(like CDE) do to resolve this ?
