nvidia-modeset ERROR GPU:0 Failed to allocate display engine core dma push buffer

[edice]

Description: Linux Mint 20
Release: 20

Hi,

I suffered from a bug when resuming my laptop,
the error would say something related to the "dma push buffer"

I googled and found this thread on the problem, which has been going for a long time.

https://forums.developer.nvidia.com/t/regression-460-series-black-screen-on-boot-nvidia-modeset-error-gpu-failed-to-allocate-display-engine-core-dma-push-buffer/165598/33

This problem still exists on the 470 series of the driver.

I "solved" my problem by reverting back to driver 450, which wasn't an easy task as the packages disappear from the archives when new packages arrive, so I had to find them from backups and other people.

My laptop will often reset X when waking from sleep, so I'm still not operating bug-free.

The most recent post in that thread (see link) suggests that it is related to the Ubuntu/Debian packaging.

quote: -------------
So I distro-hopped from Elementary OS (Ubuntu variant) to Fedora and the issues disappeared for me. Decided to retry Elementary OS and the issue came back.

To finally fix this on my machine I uninstalled the nvidia driver deb packges and reinstall them using the NVIDIA-*.run install file instead and it worked. Now I’m running Elementary OS using nvidia without sleep-resume crashing.

Feels like whomever is packaging the nvidia-drivers for Ubuntu is doing something which doesn’t play nice with my laptop.
--------------------

So I want to bring this to the attention of the Debian/Ubuntu package team,
hopefully they can take an interest and pursue this bug, because it is a huge pain for me and others.

Best regards,
Paul
