Right now I need to use fglrx to support my 6 monitor setup, 4 of which are daisy-chained on DisplayPort with the last member of the chain using a DisplayPort to DVI adapter. If there are any proposed fixes, I would be happy to try them out.

The Dell screens are properly detected as separate: I can move mouse from one screen to another. Image on the last Dell screen is defected (blur) as in the attached picture. After login all screens switch to power safe mode. Afterwards, I'm able to switch to CLI (ALT+CTRL+F2) but screens is doubled on two Dells (they are treated as one), laptop's screen remains off.
