With the mainline kernel you linked, I get different behaviour: Most of the time after suspending and waking up again, the system freezes completely (sometimes immediately to a black screen, sometimes I can see a second roll over on the clock before it freezes). In this frozen state, the mouse and keyboard don't work, nothing changes on the screen an I cannot switch to another TTY. Pressing capslock and numlock doesn't change the indicator LEDs on the keyboard.
Of the couple times I tried, the system woke up correctly two times. Those two times, everything worked normally and there was no flickering. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1885363 Title: [amdgpu] Screen flickers after waking up from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1885363/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
