Way to reproduce on an intel laptop: 1) Plug in an external monitor over VGA 2) Cycle fn+f8 a bunch of times
It usually happens within 20 cycles, and usually during the external monitor only (internal screen off) to internal monitor only (external off) transition. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/838128 Title: compiz assert failure: compiz: /usr/include/boost/smart_ptr/shared_ptr.hpp:418: T* boost::shared_ptr<T>::operator->() const [with T = UnityFBO]: Assertion `px != 0' failed.
