ANY Linux Catalyst Driver > 14.12

With the recent release of Catalyst 15.7, I have tried again with my configuration which works using Catalyst 14.12.  Once again, I am faced with it not detecting my 3rd monitor, only showing 1 monitor, or not booting at all.  I do not get a response when trying to find out why from AMD.  The only response I've received was from another user with an inaccurate response.  Is there a known issues list which states that DisplayPort MST is no longer working in the latest drivers?  Did AMD drop support for DisplayPort MST? Is there a conflict that I'm unaware of?  Should I stop caring about trying to have the latest drivers?  (Frustrated because of new releases wasting my time)



Ubuntu 14.04

Caicos XT [Radeon HD 7470/8470 / R5 235 OEM]
(AMD Radeon HD 7000 Series)

1 Dell MST montior connected to the DisplayPort chained to another Dell Monitor (DisplayPort MST)

1 Dell monitor connected to the DVI port.


Works on CCC 14.12 and shows the appropriate DisplayPort information.

Does not work on any version beyond CCC 14.12.
