Debian+XFCE freezes randomly either just before, during, or a couple seconds after the login screen. It happens about a third the time, both on booting and on changing users. During a freeze, the screen displays but is not updated and the USB ports appear inactive. There is no mouse or keyboard input, not even from SysRq. The only thing to do is a hard shutdown with the power button.
I first installed Trixie and had this problem and others. Downgraded to Bookworm and have just this problem left. The machine is a ThinkCentre M920q with i5-9600T, 8GB RAM, and UHD Graphics 630. Have already had some discussion of log output on Debian User Forums. Computer freezing because of LightDM?https://forums.debian.net/viewtopic.php?t=162147
