I just discovered today that I can no longer get to the GUI desktop on my NUC. The monitor never wakes up. The last time I was in was approximately a month ago, and since then I have installed updates once a week.

I've tried the obvious solutions:

• Rebooting
• Switching HDMI cables
• Switching monitors

The NUC is just over 4 years old with HDMI video and USB keyboard and mouse. Around a year ago the fan started failing and was replaced, but it's had no further hardware issues. I've been attempting to troubleshoot software before blaming either the video or USB hardware (if the USBs for the keyboard and mouse were failing, the monitor wouldn't wake up).

After running:

lshw -c video
modinfo i915

I see the driver file is:

/lib/modules/4.15.0-166-generic/kernel/drivers/gpu/drm/i915/i915.ko

This is dated 2021-12-08 12:15:03 in the filesystem.

From the driver information, I'm not sure what the relevant entry would be in the apt logs. I've looked through these two files whose log information covers the range starting from Dec of last year:

/var/log/apt/
2022-01-17 09:06:20 history.log
2021-12-21 00:53:22 history.log.1.gz

But I'm not sure how the driver would match up with the entries there. On 2022-01-05, there were the following entries that match the folder the driver file is in (4.15.0-166):

Start-Date: 2022-01-05 00:53:08
Commandline: apt-get -y install linux-generic
Install: linux-headers-4.15.0-166-generic:amd64 (4.15.0-166.174, automatic), linux-modules-4.15.0-166-generic:amd64 (4.15.0-166.174, automatic), linux-image-4.15.0-166-generic:amd64 (4.15.0-166.174, automatic), linux-modules-extra-4.15.0-166-generic:amd64 (4.15.0-166.174, automatic), linux-headers-4.15.0-166:amd64 (4.15.0-166.174, automatic)
Upgrade: linux-headers-generic:amd64 (4.15.0.163.152, 4.15.0.166.155), linux-image-generic:amd64 (4.15.0.163.152, 4.15.0.166.155), linux-generic:amd64 (4.15.0.163.152, 4.15.0.166.155)
End-Date: 2022-01-05 00:53:45

But again, I'm not sure if these are related or not.

I appreciate any suggestions.
