Thanks very much—the problem has been resolved for both the NVIDIA and the nouveau driver.
1. I had not been able to switch to the nouveau driver when the problem first appeared, due to unresolved dependencies involving libllvm19, libatomic1, and libedit2. Now I have resolved this problem, and the nouveau driver could be activated and works fine. 2. Adding "nomodeset" to the boot options enabled the boot to 6.8.0-117-generic fine, with the NVIDIA driver loaded and working fine. 3. In 6.8.0-117-generic, I switched to nouveau using the Software Updater, rebooted (for the test), then switched back to nvidia-driver-470 again with Software Updater, and now I can boot without the freeze to 6.8.0-117-generic and the NVIDIA driver. I don't know what got reset, but I had tried power down earlier just wondering about the card, but that didn't work. And the attempt to switch to nouveau also failed initially. In any case, my "bug" seems nicely resolved now, thanks!

Learn why this is important at https://aka.ms/LearnAboutSenderIdentification ] Hi Rick To narrow down the root cause, Could you please try booting kernel 6.8.0-117-generic with the `nomodeset` kernel parameter? Steps: 1. At the GRUB boot menu, highlight the 6.8.0-117-generic entry 2. Press `e` to edit 3. Find the line starting with `linux` and add `nomodeset` at the end (before `quiet splash`) 4. Press `F10` to boot If the system boots successfully with `nomodeset`, it confirms the issue is related to the NVIDIA driver initialization rather than the kernel itself. I should also share some important context: the nvidia-driver-470 is end-of-life — NVIDIA no longer maintains or updates this driver branch. There are probably only two options if it really is NVIDIA driver issue: 1. Pin the working kernel (short-term): sudo apt-mark hold linux-image-generic linux-headers-generic This keeps you on 6.8.0-111. 2. Switch to the nouveau driver (recommended): The open-source nouveau driver supports your Kepler GPU and will remain compatible with future kernel updates. sudo apt remove --purge nvidia-driver-470 sudo reboot Ubuntu will automatically fall back to nouveau.

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.
