I have not run into this problem before, until i started installing 11.2 and higher. When i install the new catalyst software, it warns me that the screen will flicker during the driver install. it always flickers, and then goes back to me being able to see the desktop again. since installing 11.2 and higher (i am running 11.7) my screen flickers, but doesn't kick back to the desktop.
i do not know hoe far along in the install it is at this point, wait maybe 5 minutes, then press the reset button on my pc to reboot. normally it asks me if i want to reboot after installation, but i don't see my desktop after the flickering.
I normally have my eyefinity grouped when installing when it happens, but i tried reinstalling with eyefinity ungrouped, and it still happens.
