Hi

I find on internet morpheus-0.3 project.

and had had this problem:
#gdb morpheus
GNU gdb Red Hat Linux (5.3.90-0.20030710.41rh)
This GDB was configured as i386-redhat-linux-gnu...Using host
libthread_db library /lib/libthread_db.so.1.
(gdb) run
Starting program: /usr/local/bin/morpheus
[Thread debugging using libthread_db enabled]

The gdk_gl_query function comes in gtkglarea-1.2.2-17 rpm.

finding gdk_gl_query in code, only this lines in ./src/main.c

if( gdk_gl_query() == FALSE ) {
g_print( no OpenGL capability\n );
return 0;
}
Well, I deleted this 4 lines from code and morpheus works well.

I try this with mesa from cvs+savage dri and in other computer with
XFree4.4 from cvs and with X.org R6.7 compiled from sources,
the difference was when morpheus runed with XFree4.4 instead of
Segmentation fault, gdk_gl_query() return FALSE.
I'm cross-replying to the DRI list in case anyone there is familiar 
with the problem.  Though, I don't really understand what you're 
saying at the end.

I test in my laptop with dri cvs trunk savage drive.
and at work, on one desktop P4 xenon with one SIS 671FX, I try 2
differents sources Xfree4.4cvs and X.org R6.7 plus SIS drive 20040424.
with X.org, gdk_gl_query() give segmentation fault, with Xfree4.4cvs
returns FALSE, that is not wight either.

all with Fedora Core 1 OS 

Thanks,

The NULL dpy pointer passed to glXQueryExtension seems suspicious.
