Can you please try again on kernel 5.8 and gather another log? The problem with the log in comment #6 is that it ends too early -- when the system suspends. And doesn't show anything about trying to resume from suspend. This is a common issue with these kinds of bugs. To make it more likely that a complete log is written please hit these keys after resuming from suspend (when the display isn't coming on):
Alt + SysRq + S and then reboot. Or you can do it all in one: (Holding Alt+SysRq) R,E,I,S,U,B https://en.wikipedia.org/wiki/Magic_SysRq_key -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890863 Title: [amdgpu] Display does not come on after suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1890863/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
