I tried turning the TV off with the remote, then turning the TV back on. Looks like the same (or similar) condition. All the windows on the second display lost their geometry. I can see them in the launcher view, but they are gone somewhere. Perhaps their coordinates have traveled off-screen? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-amdgpu in Ubuntu. https://bugs.launchpad.net/bugs/1892427 Title: [amdgpu] HDMI connected TV wakeup problems Status in xserver-xorg-video-amdgpu package in Ubuntu: Incomplete Bug description: The setup here is critical to understanding the problem. A laptop is connected via HDMI to a TV monitor. Two displays are thus available to the OS. Everything works great both in mirror display and regular display. At the end of day, I lock the user account and the display manager (DM) tells the monitors to blank (sleep?). When I touch the DM and login the laptop display livens up and looks good. However, the TV display often doesn't and I need to wake up the TV with the TV control stick. This works OK, and the second display comes back. And all the windows associated with that display return from sleep OK. *HOWEVER*, all the geometry for those windows (term windows is one example) are lost. I can see the windows in the term overview, but I cant get to them on the second display.
