On real server hardware (IPMI/BMC AST chip + nomodeset) the VESA
framebuffer is set by BIOS at whatever resolution it chooses (often
1024x768 or 1280x1024). The hardcoded 1920x1080 Modeline caused X to
fail → LightDM crash-loop → SOL console flooded with systemd messages.
- Remove Monitor section / Modeline from xorg.conf — fbdev now uses
whatever framebuffer resolution the kernel provides
- Add lightdm.service.d/bee-limits.conf: RestartSec=10,
max 3 restarts per 60s so headless hardware doesn't spam the console

startx from autologin shell targets VT1 directly — KVM sees the
graphical UI without VT switching. Remove bee-desktop.service
(systemd-launched X defaults to VT7, invisible on KVM).
Add xserver-xorg-video-fbdev for server AST/VGA framebuffer.

loglevel=3 was hiding all kernel messages on tty0/ttyS0 except errors.
Machine crashes (panics, driver oops, module failures) were silent on VGA.
Restored loglevel=7 so kernel messages up to debug are printed to both
tty0 (VGA) and ttyS0 (SOL). Journald MaxLevelConsole reduced to info
(was debug) to reduce noise on SOL while keeping it useful.

Without a keepalive the kernel watchdog timer expires and reboots
the host mid-audit. Configuring RuntimeWatchdogSec lets systemd PID 1
reset /dev/watchdog every 30 s — well within the typical 60 s timeout.
