xinerama - mouse pointers - red hat
I have a really strange problem which I have fixed but I don't understand why.
I have just upgraded my office PC to RH9. Was previously running Mandrake. I have a multiheaded Ati Radeon 7500. I had two monitors configured using the xinerama extension.
When I configured RH to use xinerama everything worked fine until I moved my mouse off one of my screens. The moment I did that the screen wnet black. It only happened on one screen not on the other.
I changed my mouse pointers to white ones and the edited my /usr/share/default/index.theme file and removed the line inherits = bluecurve. Restarted X and everything works.
I did this as a friend ghad the same problem on a diff distribution when running with cusom mouse pointers and it solved his problem.
My question is why did this work and what was the problem.
