* VT compatibility
|
|
* If the kmscon application runs in a VT we need to react on VT switch events
|
|
* to allow other applications to access the DRM. This is only needed as long as
|
|
* we run in a VT. In the future we will be able to disable all VTs and run as
|
|
* service daemon. We then need another way to switch between graphical
|
|
* applications, though.
