Public bug reported:
Failure to boot system with three monitors and NVIDIA driver. Freezes at black
screen or screen with Ubuntu text. Diagnostics (ChatGPT assisted) included this
conclusion:
+++Diagnostic+++
The failed boot’s journal simply stops abruptly at 09:25:12, while systemd is
still in very early boot, just after starting Plymouth and flushing the journal
to disk. There is no later evidence of reaching normal multi-user startup, let
alone GDM.
That makes this look like a hard freeze during early boot:
The NVIDIA 470 modules do load.
The machine then continues briefly through early device and systemd
initialization.
Logging stops suddenly before the display manager starts.
(A separate user with Ubuntu 24.04.4, kernel 6.8.0-117, and an older NVIDIA GT
710 reports a strikingly similar failure, with 6.8.0-111 still working.)
Kernel 6.8.0-117 is likely triggering a low-level regression on older
NVIDIA 470-series systems, causing a freeze during early graphics-
related boot initialization.
++++++++++summary+++++++++++++
Regression: 6.8.0-111-generic boots; 6.8.0-117-generic hard-freezes.
GPU/driver: GeForce GT 730 GK208B, nvidia-driver-470 470.256.02.
Symptoms: DP screens black/frozen splash, DVI screen multicolored stripes.
Logs: NVIDIA module loads successfully; journal stops abruptly during early
boot before GDM.
Topology test: unplugging DVI or DisplayPort did not change the failure.
