Figure out why nvidia-smi is not showing my graphics card
Reasoning
**Troubleshooting GPU access**
I need to figure out why `nvidia-smi` isn’t showing the GPU on the user's machine while we're in the
Codex CLI. The shell commands can help, but many might require higher permissions, especially for access
outside the current directory or system commands. I wonder if `nvidia-smi` needs to access `/proc`, which
could be an issue. If it fails due to sandbox restrictions, I'm thinking we should try asking the user
for more context before requesting escalated permissions.
**Planning GPU diagnostics**
I've got instructions to keep going until we solve the GPU issue, so let's run a series of
diagnostics. I’m thinking of executing commands like `nvidia-smi`, `lspci`, and others to gather information,
but accessing directories like `/etc` and `/proc` might need escalated permissions.
Before running these diagnostics, I should send a brief message to explain my plan. Since it's a
multi-step process, I’ll outline a plan with 5-7 steps, starting with `nvidia-smi` to capture any errors,
checking for the NVIDIA GPU, and listing driver modules.
**Executing hardware diagnostics**
I’m planning to inspect kernel and device logs for any NVIDIA errors, check for conflicting drivers like
Nouveau, and summarize potential fixes. Before running any commands requiring escalated permissions, I’ll send
a preamble message to explain my next steps, like running `nvidia-smi` and basic hardware checks.
The commands include checking the NVIDIA version, loaded modules, and the current kernel version. I’ll use
tools like `rg` or `grep` depending on availability, noting that sandbox restrictions will limit output to 256
lines. Let's move forward with this plan!
Assistant
I’m going to run `nvidia-smi` and a few hardware/driver checks to pinpoint why the GPU
isn’t detected.

Reasoning
**Troubleshooting Nvidia Driver Issues**
I'm looking at the issue with `nvidia-smi` — it exists but isn't communicating with the driver. This
could be due to the driver not being loaded, a mismatch, secure boot preventing the module, or possibly an
issue with the WSL (Windows Subsystem for Linux) environment. I’ll keep going through the steps to resolve
this and see if I can pinpoint the cause. Let's explore these possibilities!

Reasoning
**Investigating GPU drivers**
I can see that the 4090 is present, but it's showing `nvidiafb` instead of the proprietary `nvidia`.
There's also no kernel driver in use, which is odd. It seems the driver lines didn't show up because
none are loaded. Since `nvidiafb` is the old framebuffer driver, either the nouveau or nvidia driver might not
be loaded. Next, I’ll need to check the modules with `lsmod` to get more clarity on the situation.

Reasoning
**Checking installed drivers**
I see that DKMS is showing `nvidia/575.64.03` installed for the kernel version 6.8.0-55-generic. However, I
want to ensure that I'm checking the current kernel version correctly. I need to run the `uname` command
to verify what the current kernel is. It's important to confirm this, as I want to make sure everything
is aligned and functioning properly! Let’s take that next step and check the kernel version.

Reasoning
**Evaluating the kernel situation**
I see that we're dealing with Google Cloud Platform's kernel, which makes me think we might be on a
GCP VM. It's curious, especially since we're noting PCI devices for an RTX 4090. I wonder if it’s
possible the system is using Canonical's Kernel for GCP. The installed DKMS module is for a different
kernel version, and the NVIDIA module isn’t loaded. We need to build it for the current kernel or switch to a
matching one, and secure boot might impact loading. I’ll check the secure boot status.

Reasoning
**Checking driver details**
I see that no logs indicate there wasn't an attempt to load the driver. It's crucial to check
whether the `nvidia` kernel module is present for the current kernel. I'll run the command `modinfo
nvidia` to see if it exists. This step is necessary to ensure everything is functioning correctly with the
driver, so I'm curious about what the output will reveal! Let's get that information and move
forward.

Reasoning
**Troubleshooting kernel modules**
I'm checking why `modinfo` returns nothing, which suggests that the module is not found for this kernel.
I’m thinking I should look into installed packages to confirm if the NVIDIA driver is present. I'll run
`dpkg -l | grep -E '^ii\\s+nvidia-driver'` to see if the driver is installed correctly. This way, I
can understand if there's an issue with the driver or something else entirely. Let’s see what I find!

Reasoning
**Analyzing kernel installation issues**
I see that packages are installed and DKMS built for an earlier kernel version, but now we’re running
6.14.0-1012-gcp on Ubuntu 24.04. The default kernel typically is 6.8. The presence of a discrete GPU suggests
an accidental use of the gcp kernel for a desktop or perhaps using Ubuntu’s livepatch. DKMS hasn’t built the
module for the current kernel; it might be missing headers. I should check if the kernel headers for this
version are installed.

Upgrade me to the latest correct kernel, not the gcp one (uninstall the gcp one, dunno
how that got there)
Reasoning
**Considering kernel changes**
I'm planning to gather the current package state regarding Linux images before making changes, using
specific commands. Next, I'll install the generic kernel meta, which involves updating with apt-get and
ensuring that the modules match the installed version. There's a lot to keep track of, especially the
dependencies between various packages on Ubuntu 24.04. After that, I'll carefully remove the Google Cloud
packages, ensuring not to disrupt the currently running kernel. Running update-grub afterward seems essential
too.
**Planning installation steps**
The next step is to schedule a reboot and blacklist the nouveau driver to ensure the NVIDIA driver installs
correctly. After the reboot, I'll need to verify that the generic 6.8 kernel is running and that
'nvidia-smi' works. Since I can’t reboot myself, I’ll instruct the user to do so and ask for their
permission for commands that need elevated access. I'll update the plan to add these steps and ensure we
can handle unattended upgrades too. Let's get moving!

Reasoning
**Verifying kernel installation**
I see that the latest installed generic kernel is 6.14.0-27. I need to make sure DKMS can build for this
version, which usually happens during boot. However, headers like 'linux-headers-6.14.0-27-generic'
should be present, but I didn't see them mentioned. I'm considering whether they need to be
installed to match the kernel version. If 'linux-generic' is installed, it may only install headers
for the 6.8 series. Overall, I need to check the headers and decide which kernel to boot: 6.8.0-71 or
6.11.0-29 generic.
**Assessing kernel options**
It looks like there are multiple meta or hardware enablement (HWE) tracks, particularly the
'linux-hwe-24.04' which might use the 6.11 kernel. The installed image is
'linux-image-6.11.0-29-generic', so that’s good. I consider going with the recommended stable
option, 'linux-generic-hwe-24.04'. However, I need to ensure we keep the appropriate generic images
and remove GCP ones. After rebooting, GRUB will choose the highest version, likely 6.14.0-27. I should check
installed headers for 6.11 and 6.14 to ensure NVIDIA DKMS builds effectively.
**Determining the correct kernel**
The user's goal is to find the "latest correct kernel," likely referring to the standard
generic meta for HWE. My plan is to install 'linux-generic-hwe-24.04',
'linux-headers-generic-hwe-24.04', and 'linux-modules-extra...' but I’m unsure if these
packages exist in 24.04. I remember that HWE is usually for LTS, and it seems they exist. I can check with
apt-cache policy. The system currently has the 6.11.0-29 generic image, so I need to ensure the headers for it
are installed.
**Checking DKMS and kernel headers**
It seems that DKMS can build on the first boot, even without prior header installation, but it still needs
those headers. The 'linux-image-6.14.0-27-generic' package doesn't depend on headers, and the
6.8 meta won't pull the 6.14 headers. I need to ensure the correct headers are installed for whichever
kernel is set to boot. For instance, setting the default to 6.8.0-71 could work since it has headers and DKMS
built for 6.8.0-55, but it appears NVIDIA didn't build for 6.8.0-71. I'll need to confirm the
headers and DKMS status.
**Switching to the correct kernel**
Since the user wants to move off GCP and get the "latest correct" version, I’m planning to install
'linux-generic-hwe-24.04' and 'linux-tools-generic-hwe-24.04'. First, I'll check the
apt cache to see which meta packages are available. Once I have that information, I'll remove the GCP
meta packages. My next step is to run apt-cache policy for 'linux-generic-hwe-24.04',
'linux-image-generic-hwe-24.04', and 'linux-headers-generic-hwe-24.04' to confirm their
installation status.

**Installing HWE Kernel Components**
Alright, I’ve identified the HWE kernel candidate version 6.14.0-27, which matches the installed generic
image. However, it looks like headers aren't installed. I need to set up the HWE meta packages to ensure
all necessary headers and modules are included. So, I’ll install 'linux-generic-hwe-24.04', which
will pull in the required components. After that, I’ll purge the gcp meta and images to clean things up. Next,
I'll update the system and check on the nvidia-dkms module too.

Reasoning
**Providing installation steps**
I need to outline clear steps for the user to install the latest generic kernel and remove the gcp kernel.
First, I should ensure the headers are installed, handle the default kernel in grub, and check for an
initramfs update. After rebooting, I’ll guide the user to install the NVIDIA driver modules or verify DKMS
builds for the current kernel, making sure Secure Boot is off, blacklisting nouveau, and loading nvidia. I
also see that both generic and gcp kernels are installed, so I’ll advise on setting GRUB defaults accordingly.
**Planning kernel installation**
I need to be cautious about purging the gcp kernel while it’s running, as that could remove the current kernel
image. Apt typically doesn’t allow removal of the running image by default, but I can remove other installed
kernel images. The plan is to reboot into the generic kernel first, then purge the gcp kernel.
I’ll install the HWE generic metapackages using the command `apt-get install linux-generic-hwe-24.04`, which
includes the necessary dependencies. This will ensure that future updates work smoothly, and I’ll check if
linux-modules-extra is installed for compatibility with the generic images.
**Updating GRUB and verifying modules**
I need to ensure that if the metapackage is installed, the modules-extra will be present. My first step is to
update GRUB to default to the generic kernel. I can use the `grub-reboot` command to select a specific entry
for the next boot, or a simpler way is to use `grub-set-default` along with `update-grub` to set the default
entry.
After rebooting into the generic kernel, I should verify that the output of `uname -r` shows the correct
version. Then, I’ll check that `modinfo nvidia` indicates the module is present for this kernel, ensuring DKMS
builds the module appropriately.
**Managing NVIDIA and kernels**
After booting, I can trigger DKMS to autoinstall with the command `sudo dkms autoinstall -k $(uname -r)`.
Alternatively, I can reinstall the NVIDIA driver using `sudo apt-get install --reinstall nvidia-dkms-575` and
ensure that the matching `linux-headers-$(uname -r)` are installed.
Next, I'll confirm that Nouveau is blacklisted by checking with `lsmod | grep nouveau` and adjusting the
blacklist file if necessary. Afterward, I can load the NVIDIA modules with `sudo modprobe nvidia nvidia_uvm
nvidia_drm modeset=1` or simply reboot. Once everything is set up, I'll check that `nvidia-smi` works.
Once the generic kernel is running, I can purge gcp kernels with `apt-get purge 'linux-image-*-gcp'
'linux-modules-*-gcp'`, and I'll show a safe command to review which gcp packages are
installed. Optionally, I might also consider removing older generic GA kernels if desired, while ensuring at
least two kernels are kept.
**Final Installation Steps**
Here’s a clear procedure for you to follow for upgrading to the latest correct kernel and removing the gcp
kernel. Since we can't use sudo together, I'll provide the commands to run:
- **Install HWE generic kernel and headers (if not already):**
```
sudo apt-get update && sudo apt-get install -y linux-generic-hwe-24.04
```
- **Verify installed kernels:**
```
dpkg -l | rg 'linux-image-.*-(generic|gcp)$'
```
- **Make GRUB default to generic 6.14:**
```
grep -P "menuentry 'Ubuntu.*6\\.14\\.0-27-generic'" -n /boot/grub/grub.cfg
sudo grub-set-default "Advanced options for Ubuntu>Ubuntu, with Linux 6.14.0-27-generic"
sudo update-grub
```
- **Reboot:**
```
sudo reboot
```
- **After reboot, install headers for the running kernel:**
```
sudo apt-get install -y linux-headers-$(uname -r)
```
- **Rebuild NVIDIA DKMS for the current kernel:**
```
sudo dkms autoinstall -k $(uname -r)
```
- **Purge GCP kernels:**
```
apt list --installed | rg gcp
sudo apt-get purge -y 'linux-image-*-gcp' 'linux-headers-*-gcp'
'linux-modules-*-gcp'
sudo update-grub
```
Feel free to check every command before running them. Once you've done this, reboot again, and let me
know how it goes!
Assistant
Got it — here are the exact commands to switch to the latest generic kernel (HWE),
boot into it, and remove the GCP kernels. Run them in order.
Install the latest generic kernel
- Update + install HWE meta: `sudo apt-get update && sudo apt-get install -y linux-generic-hwe-24.04`
- Verify images present: `dpkg -l | rg 'linux-image-.*-(generic|gcp)$'`
Make GRUB default to the generic kernel
- List generic entries: `grep -n "menuentry 'Ubuntu, with Linux .*generic" /boot/grub/grub.cfg`
- Set default to the latest 6.14 generic (replace the title with your exact match):
`sudo grub-set-default "Advanced options for Ubuntu>Ubuntu, with Linux 6.14.0-27-generic"`
- Update GRUB: `sudo update-grub`
Reboot into the generic kernel
- Reboot: `sudo reboot`
- After login, confirm: `uname -r` (should show something like `6.14.0-27-generic`)
Ensure NVIDIA driver builds for the running kernel
- Install matching headers: `sudo apt-get install -y linux-headers-$(uname -r)`
- Rebuild DKMS for this kernel: `sudo dkms autoinstall -k $(uname -r)`
- Load the module: `sudo modprobe nvidia`
- Check: `nvidia-smi`
Purge GCP kernels (after you’re booted into generic)
- Review what’s installed: `apt list --installed | rg gcp`
- Remove GCP kernels:
`sudo apt-get purge -y 'linux-image-*-gcp' 'linux-headers-*-gcp'
'linux-modules-*-gcp' linux-gcp || true`
- Refresh GRUB: `sudo update-grub`
If nvidia-smi still fails
- Check modules loaded: `lsmod | grep -E 'nvidia|nouveau'`
- If `nouveau` appears, blacklist it and reboot:
`echo -e 'blacklist nouveau\noptions nouveau modeset=0' | sudo tee
/etc/modprobe.d/blacklist-nouveau.conf >/dev/null && sudo update-initramfs -u && sudo
reboot`
- Reinstall DKMS if needed: `sudo apt-get install --reinstall -y nvidia-dkms-575`
Notes
- Secure Boot is already disabled on your system (good).
- Installing `linux-generic-hwe-24.04` keeps you on the latest supported generic kernel track for Ubuntu
24.04.
- Keep at least one previous generic kernel installed as a fallback.
