[gutsy] after dist-upgrade from feisty,the xserver-xorg-video-ati 1:6.6.193-1ubuntu1 give me a freeze black screen

Binary package hint: compiz

following instrucions form release notes from tribe3 .
I just test making a simple dist-upgrade ( update-manager -d with sources.list with gutsy trunk) from feisty with all updates.

after reboot, the screen is black ( or blank ? :P) and seems freeze with xserver-xorg-video-ati driver.

With xorg-driver-fglrx restricted there is no problem except when I run the command "xdpyinfo -ext all " that make the screen freeze and I have to restart sometimes the X system and other times the computer.
