What's error code 2?  Is it BadMatch?  (really libXg should print these
things properly).

My guess is that libXg is trying to allocate an 8-bit pixmap on
your 24-bit only display...

2 maps to this text:

BadValue (integer parameter out of range for this operation)

i tried the quick-and-dirty approach of commenting out the
case allowing a depth of 0. that failed with a BadMatch
error.

has anybody else seen this problem with sam on unix:

with an exported display (or just running under Xnest)
sam starts up normally but
when you place the window with whatever window manager
you're using sam commits suicide with this error:

libg error: i/o error:

not terribly informative. wily doesn't have the same
problem. i did a little debugging on it but the error
message is bubbled up to libg from a callback from

where E is an XErrorEvent* (my modification). gcc claims that E is:

$2 = {type = 0, display = 0x8065530, resourceid = 32, serial = 49,
  error_code = 2 '\002', request_code = 53 '5', minor_code = 0 '\000'}

according to the X headers, 53 is a pixmap thing. but i'm not quite
sure what to do from here. i am not an x guru.
