Editing this question in the hope that someone could find it useful.
After automatically updating drivers and kernel on Ubuntu 22.04 the laptop GPU stopped working. There was no apparent reason and the problem happened suddenly, after rebooting from suspend.
Symptoms to look out for -
- The laptop would boot to a black screen or a black screen with a thin line at the bottom of the screen, showing the colour of the background.
- Boot log would show something like this. “Failed to start Detect the available GPUs and deal with any system changes.”
Attempted fixes - (the same problem, as mentioned above, persisted after every fix)
- Reinstalled Ubuntu 22.04/18.04
- Not updating the kernel/updating the kernel
- Using Ubuntu “software and updates” selecting the gpu driver.
- Nvidia drivers tested 470, 490, 515 (open and proprietary) and 525 (open kernel and proprietary)
- Building Nvidia drivers from source.
Solution -
- Laptop was returned to the seller and they confirmed that it was a faulty GPU.
