While this seems to be a problem for debian-user its very sensible that the issue was raised here as well. I stumbled upon this issue on two laptops and I consider this a serious issue for the Buster release that. Users ending up with a black screen in a not so uncommon setup is something we need to avoid. I intended to write a bug report about this soon. > Raj Kiran Grandhi <grajki...@gmail.com> writes: > > > In a fresh install of Buster with XFCE desktop, locking the screen > > blanks the monitor and the monitor enters a power save state.

Yes, please file the bug (and may be report the bug number here). We should not release with a broken greeter as default since we can not assume that normal users will find out the "switch VT trick" and instead will assume the box is frozen.
