Created attachment 122660 [details] Xorg log for radeon Xorg log when trying to use the radeon driver.
I have attached a sample Xorg configuration for using the radeon driver, basically the Ubuntu fglrx configuration (fglrx works on Ubuntu 15.10) with "fglrx" replaced by "radeon". The radeon driver basically seems unable to find a screen to its liking, > (EE) RADEON(0): No modes. > (EE) Screen(s) found, but none have a usable configuration. and then gives up altogether:- > (EE) no screens found(EE) This happens irrespective of whether the module parameter radeon.runpm = 0 or not. Trying to use vga_switcheroo with echo DDIS > /sys/kernel/debug/vgaswitcheroo/switch results in a reversion to the login screen with a message saying that client 0 refused to switch, or in a totally black screen (but the system keeps working and can be powered off normally by pressing the power button), after logging out, depending on the display manager being used (the former typically happens with GDM).

Please file your own report, including the corresponding dmesg output.
