I have never run X11 on 10.4 intel!  I compiled xorg on my 
headless intel mac pro because I have it set up as a deb 
server and wanted to compile everything against xorg rather 
than apple-X11, same as I do on my ppc machines.  I did all 
my testing for compatibility of debs between 10.4 and 10.5 
using ppc machines, then, when I got the new intel machine I 
proceeded to apply the same setup...

So the patch never got applied to fink's xorg??  Anyone 
running X11 on 10.4 intel has stuck with apple-X11 and 
applied the patches to that??  I'm just a bit gobsmacked to 
discover this.  I'm not complaining, I know there is plenty 
else on the to do list, I'm just very surprised...

OK.  So this suggests that I should try to patch it on 10.4, 
where I know it compiles, and not try to compile it on 10.5.
I'm not sure I have the time or skills to do this.  I'm 
guessing I'll have to find apple-X11 sources, see what the 
patch does to quartz-cursor.c, then try to find the 
equivalent places in Xdarwin source and apply something 
similar.

Or, I can try Tiger's X11, apply the patch, and see if 
everything still works even though it was compiled against 
xorg.  And recompile what doesn't.  And first check there 
isn't some feature in Xdarwin that I use that is missing 
from Tiger's X11...I've been using xorg since it first 
appeared in fink, so it's been a while...


many thanks for your help,
cheers,
