Hi Rajiv,
I have Xinerama working fine with R13 over here. I don't use MATLAB Desktop
though, just the shell. I run GUI applications successfully on both
screens. Here are some suggestions:
-Is OpenGL working compatibly despite Xinerama being enabled? (not the case
for me)
-Is there any element in GUI's which tends to cause more trouble? Or is it
not working altogether?
-Any problems with applications other than MATLAB?
-Can you confirm that disabling Xinerama resolves the issue?
