error starting KF5: Kwin is not stable

Hi guys!

I just make a fresh install of Archlinux using the last ISO available (2015.05.01). I installed KF5 and the propietary drivers (catalyst-hd234k) for my old Radeon HD4770, otherwise I can not use my dual head setup with open source drivers because they freezes the system when I plug the second screen (under Kubuntu it was possible to use them, surprisingly)

Once I configured the screens using AMDCCC as it is described in the wiki, when I rebooted my system it fails to start a new session. It throws this error:
KWin is not stable. It seems to have stopped unexpectedly few times in a row. You can select another window manager.

But I don't have other choices: only KWin_X11

I guess that I have to use only one screen for the moment with the open source drivers.

Re: error starting KF5: Kwin is not stable

I remember reading that you have to disable compositing (shift+alt+f12), then connect the second display, then re-enable compositing again to work.
Probably unrelated, but I've had the same message when I had selected an incompatible window decoration. Try switching to a tty and looking at the journal, it should state why kwin is crashing.
