The screen lockers work because if i enter my passwd and press enter i can login in the desktop. Additional info: If i lock/blank the screen manually and move them mouse the screen gets the signal back like it should.Issue happens across Debian and Arch distributions.Monitor is connected with an hdmi 2.0 cable. Workaround: Adding amdgpu.dc=0 in grub resolves the issue for all screen lockers in my system, but disables amd display code. -- You are receiving this mail because: You are watching the assignee of the bug. _______________________________________________ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
