Title:
compiz crashed with SIGSEGV in
unity::ui::EdgeBarrierController::Impl::OnPointerBarrierEvent()
Status in “unity” package in Ubuntu:
New
Bug description:
This happened on a Lenovo T520 laptop using the Intel video drivers. I
suspended my laptop with no external screen attached. I woke up the
laptop with my external monitor connected to the VGA port but the
monitor was turned off. When I powered on the monitor and tried to
move a window to the external monitor the window got stuck half way.
Now I can not alt tab to the open windows on my laptop screen.
I know you need more information than this but I am not sure what to
give you. I am happy to send logs or diagnostic output but I need to
restart my laptop now so I can work.
Thanks for looking at this.
