I just wanted to announce that I will be adding a new video display server. I will be adding dispserv_drmkms as long as the RA team excepts it.
What does this mean to you. Well, this implementation will of course come with CRTSwitchRes. This means no need for X11 and XRandR. This will increase compatibility and speed and it should be directly compatible with RPi2 and RPi3.
This may also bring CRTSwitchRes to the RPi4. However, will update this statement once I hit the testing stages.
