--- Comment #2 from aschm...@graphtek.com --- I'm using kwin + nouveau + 2 monitors + GeForce 8400 GS Rev. 2 + Fedora 23. I'm aware that some applications (xpra, for example) blacklist nouveau. I unchecked "Enable compositor on startup," then logged in again, and clicking "Open" in the toolbar worked! I had been actually having tearing problems, so my compositor settings were using: Open GL 2.0 GLX Full screen repaints -- You are receiving this mail because: You are watching all bug changes.
