I installed Debian 12 (Bookworm) on a laptop (Acer Aspire 5). It is the only OS on the laptop and it was a fresh install.
Everything works fine, but when I try do power off the laptop, KDE is closed and I see all the text on the first virtual console, without any progress. The computer just keeps running.
Only when I switch to the virtual console 7 (Alt
+F7
) does the shutdown continue normally (with the normal shutdown log messages filling the screen before finally turing the laptop off.
Switching to any other virtual console just shows a blank black screen.
