Like venam, I'm on a single-user, home machine that I rarely shutdown or logoff. Other than kernel upgrades, there's no reason to. At night I put it into hibernation to save power.

I was running lightdm for a while. It came with MXLinux's default XFCE. But when I switched to spectrwm I went back to the old-fashioned startx approach. Here again, I only need to use that to upgrade the window manager to a new version (I'm following the bleeding edge of spectrwm via git, and it's being getting some recent updates.)
