--- Comment #6 from Vlad Zahorodnii <vlad.zahorod...@kde.org> --- The fbdev backend should work even with nomodeset=1. Can you check whether kwin starts with KWIN_FB_NO_HW_VSYNC=1? By default, kwin tries to synchronize compositing to hardware vblank events. Some (bad) fbdev drivers don't implement FBIO_WAITFORVSYNC. -- You are receiving this mail because: You are watching all bug changes.
