Public bug reported:
After upgrading from Ubuntu 8.04 to Ubuntu 9.04 RC, enabling the
Xinerama server option with the fglrx driver crashes X. This is simliar
to bug #355841, but since that was for i386 I wanted to file another bug
for amd64. From what I can tell, on bootup the fglrx driver will finish
initializing and then crash the X server while trying to configure the
CRTCs. When X tries to start again, the fglrx driver causes a kernel
lockup during the DDC probe. The fglrx built-in Xinerama extension
appears to work fine, but since maximized windows using this extension
span multiple displays this is not a valid workaround.
