Comment 1 Wim Taymans 2020-06-15 15:09:08 UTC 
mmap failed because the dma-bufs are not mappable.
Comment 2 Wim Taymans 2020-06-15 15:17:24 UTC 
gnome-remote-desktop should check the return value of mmap().

We should however not send dma-buf to clients when it can't be mmapped, until we can
negotiate this better.
