Unknown error after apt upgrade (xserver-xorg-video-dummy:amd64 missing). Fans rev up/down continuously

us flag

I'm running Ubuntu 20.04.5 LTS on an Intel NUC 9 Pro with a Nvidia Quadro P2200

My main problem is that my fans rev up and down on a continuous loop even when the computer is idle. Temps are fine so this should not be happeing and only started after running apt upgrade which included a lot of updates including many nvidia packages. Everything seems to work fine aside from the fans spinning up.

When booting up I get these error messages:

[ 0.657529] tpm tpm0: [Firmware Bug]: TPM interrupt not working, polling instead

After reboot I get a notification in the top bar stating:

An error occured. please run Package Manager from the right-click menu or apt-get in a terminal to see what is wrong. The error message was: 'Unknown Error: '<class 'KeyError'>' ("The cache has no package named 'xserver-xorg-video-dummy:amd64'")'. This usually means that your installed packages have unmet dependencies.

When I run apt-cache search video-dummy it returns:

xserver-xorg-video-dummy - X.Org X server -- dummy display driver
xserver-xorg-video-dummy-hwe-18.04 - Transitional package for xserver-xorg-video-dummy-hwe-18.04

nvidia-smi returns:

When running watch -n 2 sensors no temps go above ≈40 degrees.

What I'm wondering is, might these error messages be related to the problem with the fans? How should I go about fixing the video-dummy error? Is this firmware bug something that needs fixing, google says it can be ignored. How would I fix the problem with the fans? I can't help but wonder if this is related to Nvidia updates.

I'm not an expert so go easy on me ;D Any help appreciated, thanks.

Can you tell if it is the GPU fan or the CPU fans?

No I can't be sure, is there a way I can find out?

You have the GPU fan speed in your output above. If you don't have the other fan speeds when running `sensors` then you should run `sensors-detect` to see if it finds fan sensors.

@rtaft I went into the Nvidia X server settings and turned the GPU fan speed to 0 and the fans are still spinning up/down indicating it's the CPU fans

@rtaft when running `sensors` I only see temps, no fan speeds or rpm's. When I run `sensors-detect` it only returns `coretemp` and asks if I want to add that to /etc/modules
aq flag
when running `sensors-detect` is there anything found in the Super IO section? Maybe a 'Yes' with an error right below it?

@rtaft yes there is this line in the Super IO section: `Trying family National Semiconductor/ITE'... Yes` `Found unknown chip with ID 0x5571`

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
