I have an Acer Aspire laptop. I hadn't upgraded it in a long time. It was still on bullseye which recently stopped receiving security updates, so I decided it was time to do it. I upgraded to bookworm which went swimmingly. Then I upgraded to Trixie which went even better. I have been using xfce for many many years and it seemed to work splendidly till I went to shut it down and found that the "Reboot" option which had always been the last option on the Apps list was no longer there, so I opened a command line window and used the command "systemctl power off"and this worked fine. I had also noticed the "halt" option in the systemctl man page and remembered decades ago using the halt command to power down computers and wondered what the difference is between that and poweroff, so I tried it. After that when I started it up again, logged in and typed 'startx', instead of seeing the normal desktop, all I see is a black screen with a mouse cursor in the middle which I can move around at will but it does nothing. Apparently halt has changed meaning since way back when.
I'm on Wayland obviously with lightdm I had a similar thing happen several years ago on a desktop computer and I never figured it out, but I created a new user which worked fine so I never bothered to spend the time to trouble shoot, but this time that isn't working. The new user gets the same black screen. I'd really appreciate suggestions. I don't have my email set up to be used from the command line so I'm sending this from my phone, which makes it difficult to cut and paste, but if more information is needed I'll do my best to supply it.
