Problem: The Nvidia-drivers are installed but the nvidia-smi command fails.

Output of the command dkms status:

nvidia, 520.61.05: added

Output of the command lsmod | grep nvidia:

DKMS should say `installed`, not `added`, for the driver to be good. You might need to run `sudo dkms install -m nvidia -v 520.61.05 -k 5.19.0-051900-generic`. However, that may not work with the kernel that you presently have installed if it doesn't contain the source headers. Sometimes mainstream kernels are missing them.

The output of `dkms install -m nvidia -v 520.61.05 -k 5.19.0-051900-generic` is: ```Error! Your kernel headers for kernel 5.19.0-051900-generic cannot be found. Please install the linux-headers-5.19.0-051900-generic package, or use the --kernelsourcedir option to tell DKMS where it's located ```

Go ahead and download and install the `headers` from https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.19/ And I am sorry about the term, I meant mainline and not mainstream.

When I try to install linux headers with `sudo apt install ./linux-headers-5.19.0-051900-generic_5.19.0-051900.202207312230_amd64.deb`, the output is: `Depends on: libssl3 (>= 3.0.0) which is not installable`. Maybe, I will try to reinstall the kernel or use a different kernel version again. However, I had troubles rebooting my computer after driver installation with earlier kernel versions. For this reason, I am currently using kernel version 5.19.

Have you thought about upgrading to 22.04 LTS? It uses the 5.15 Kernel. Or was that a kernel version that you are having issues with as well? You can also use the [HWE kernels for the LTS releases](https://ubuntu.com/about/release-cycle#ubuntu-kernel-release-cycle) where 20.04.5 LTS is using 5.15 Kernel.

Kernel version 5.11 worked for me. The Nvidia drivers are working now. For later kernels, there are dependency issues when I try to install header libraries. Thank you @Terrance

In my case rebooting helped. There was also some time where I had do downgrade the driver version by one/several versions. I haven't found any way to restart the GPU without rebooting unfortunately. For now, try with 515 version of the drivers if you don't have to absolutely depend on the most recent version. Linux has recurring problems with power management of hardware, and some devices just... don't properly wake up after boot, hibernate, sleep etc. I had the same problems with my network card for example, but in this case removing a kernel module helped.

Also you seem to be running kernel 5.19 on ubuntu 20... Unstable behavior is something I would expect from something like that.

I already tried with different kernel versions and different driver versions. The problem does not disappear with different kernels, driver versions or after reboot.

@Ukias Do you use nvidia drivers, or do you maybe have them installed, but the default is Noveau? You could follow the thread of the source code: https://github.com/NVIDIA/nvidia-settings/blob/76b10f1b028cdccfa1b524955d9b8ca719c206c6/src/gtk+-2.x/ctkwindow.c#L730, as well as checking out if disabling secure boot helps (if it's even enabled): https://forums.developer.nvidia.com/t/nvidia-settings-7578-glib-gobject-critical-1243-745-g-object-unref-assertion-g-is-object-object-failed/194647 Also: check out your dmesg and investigate if there are any nvidia errors there.

The problem disappears with kernel 5.11. Thx @Tooster

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.
