Black, Unresponsive screen when Locking Desktop Session

Question

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.

Answer 1

Have you tried maybe to switch the kernel version as it was suggested in this answer?

I've first tried (and succeeded) with a solution concerning driver update, that doesn't seem to work in your case, but maybe kernel switch could do the trick...
