# Razer x Tensorbook GPU issues

## post by tomkr on Nov 7, 2022

Deleted Lambda Stack as it wasn’t working with Pytorch or Tensorflow.

Reinstalled fresh Ubuntu 22.04, new nvidia drivers etc. Pytorch and Tensorflow worked for ~3 weeks.

Last Thursday training started suddenly going very slowly

Checked `nvidia-smi` :

> NVIDIA-SMI has failed because it couldn’t communicate with the NVIDIA driver. Make sure that the latest NVIDIA driver is installed and running.

Reinstalled 515 drivers through `Software & Updates` , restarted and got nothing but a flashing cursor on restart.

Have now:

- Uninstalled / reinstalled Ubuntu 22.04, drivers, etc, same issue
- Tried Ubuntu 20.04, same issue

Interestingly the nvidia gpu output of `lspci | grep VGA` is VGA compatible controller: NVIDIA Corporation Device 2460 (rev a1) when this should be something like `NVIDIA Geforce Ti 3080` or similar

If I change `Chipset` > `GPU Mode` to `Discrete GPU Only` I can get to the login screen, but the trackpad and mouse don’t work.

I can’t get the recovery iso image off the website as the [link doesn’t work](https://deeptalk.lambda.ai/t/recovery-image-for-razer-x-lambda-tensorbook/3121/9)

So what’s the next move here? Calling Lambda tomorrow but wondering if anyone else has experienced similar?

Is this still true? The [link](https://files.lambdalabs.com/recovery/tensorbook-jammy-20221105.iso) works just fine for me.

It worked the next day, link must have been fixed.
