Hi, In a fresh install of Buster with XFCE desktop, locking the screen blanks the monitor and the monitor enters a power save state. After that, neither moving the mouse nor typing on the keyboard would turn the monitor back on.
Typing the password without any visual feedback (while the monitor continues to be in the power save state) unlocks the screen and my session is displayed normally. Also, switching to another VT when the monitor turns off and switching back displays the unlock prompt normally. The closest I could find online was this: https://bbs.archlinux.org/viewtopic.php?id=240200 wherein installing the nouveau video driver appeared to have fixed the issue. However, that solution is not applicable in my case as I have an integrated intel graphics controller. Is anybody else experiencing this bug? Any workaround? Thanks, Raj Kiran
