How to restart Guest Additions?
Posted: 27. Jul 2020, 07:14
I have VirtualBox 5.2.42, host and clients are running Ubuntu Mate 18.04 although the same problem occurred earlier also with Ubuntu Mate 16.04.
My clients are long running, usually couple of weeks between boots. Quite often Guest Additions/shared clipboard stop working after running the client several days. Sometimes they stop working both directions, but e.g. today from host to client works but I cannot copy anything from client to host. This problem occurs with several clients.
They so far have started working again if I reinstall GA and boot the client. Sometimes they have started working also with just reinstalling GA, so without booting client. Sometimes with just booting the client, so without reinstalling GA.
I have also tried to disable shared clipboard (GUI command: Devices/Shared clipboard/disabled) and enable it back to bidirectional without any success.
My question is: Is it possible to restart GA in client without reinstalling the GA or rebooting the client? In most cases the GA version in client is uptodate, so it is most likely no use to first remove GA version X from client and then reinstall same version X into client. Maybe just stopping and restarting the GA would be enough.
