[nouveau] After reboot, the screen was blank/black and unresponsive using 5.15.0-41.44~20.04.1 (but 5.13 works)

[Bill Mills-Curran]

Although I filed this against X11, this might be a kernel issue.

I upgraded packages on 7/13/22 & rebooted today (7/15/22 -- I hadn't noted the "reboot required pop-up).

After reboot, the screen was blank/black and unresponsive. Looking at indicator lights, I believe that the system had booted OK. The syslog supports this.

Included in the update:
xserver-xorg-core:amd64 2:1.20.13-1ubuntu1~20.04.3
linux-libc-dev:amd64 5.4.0-122.138
linux-image-5.15.0-41-generic:amd64 <none> 5.15.0-41.44~20.04.1

Repeated attempts to boot all ended the same -- blank unresponsive screen.

I could boot in recovery mode and with the 5.13 kernel (which I'm running now and was used for the bug report).

Again, note that the problem occurred when booting to the 5.15 kernel.

One more note: While booting, my external (USB) monitor was disconnected.

[Daniel van Vugt (vanvugt)]

Please try these separately:

 * Add kernel parameter: intel_iommu=igfx_off

 * Use the 'Additional Drivers' app to install an official Nvidia driver.

[Bill Mills-Curran (bill-mills-curran)]

The additional kernel parameter did not help.

The additional driver (without using the additional kernel parameter) worked fine -- at least through 1 boot. The driver I installed:

NVIDIA driver metapackage from nvidia-driver-515 (proprietary, tested).

Thanks for your help.
