When locking, the screen goes black and the system becomes unresponsive. I have looked carefully for available solutions and have tried them. None have worked for me. I am using Radeon R9 285/380 with the proprietary drivers. The X.ORG drivers do not support the resolution/type of my screen. Has anyone come up with a solution to this problem?
I am having the same problem as Black screen when try to lock screen and Once locked, screen stays black and cannot be unlocked
Update: I have manually installed AMD's proprietary driver and it did not fix the issue.
