This is *probably* bug 1877774 so wait until that fix is released for 20.04.
If the problem still happens after that then please follow these instructions: https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment ** Changed in: xorg (Ubuntu) Status: New => Incomplete ** Package changed: xorg (Ubuntu) => gnome-shell (Ubuntu) ** Summary changed: - Xorg freezes after Lock (win+L or via Menu>Lock) + Screen freezes (stays black) after Lock (win+L or via Menu>Lock) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1883334 Title: Screen freezes (stays black) after Lock (win+L or via Menu>Lock) Status in gnome-shell package in Ubuntu: Incomplete Bug description: This started to happen after installing the last update last week. If I lock the screen (using either Win+L or opening the menu and clicking Lock) the screen turns to black and it doesn't come back anymore. I know the system is still operational since the NumLock button still responds (turns on and off If I press it) and the HotSpot still works on my phone, but the screen just doesn't come back from black. This wasn't an issue before the update, it is very recent. Thank you very much!
