You have been subscribed to a public bug: I had a workaround for this in 20.04, press and hold Win+L so it types letters into the input field as you lock the computer. This kept the screen from going black, and I could manually dim the laptop screen (fn+brightness) and walk away. In 22.04 the screen now fades to black immediately when I press Win+L, even though I can see the first few characters being entered on the input field as the screen fades to black.
Black screen (as in fade to black for inactivity) seems to be irreversible on this computer, no amount of mouse-wiggling, 3 finger salute (ctrl-alt-delete), or usb dongle removal and reattachment will cause the display to wake up. In 20.04 I could get around this on computer lock by continuing to press Win+L until the input box had lots of input. That seemed to stop the screen from dimming in 20.04. Not working in 22.04. The only way I have found out of this is to do a hard power down (7+ seconds pressing power button). For obvious reasons I prefer not to do this often.
