Hello,

Setting my kde neon on a dell precision m3800 wit quadro k1100m

For the past few days i can’t manage to get nvidia drivers to get working, so far my diagnosis is that nvidia-drm cannot be installed.

So far i tried installing all of the latest drivers including: 384 390 396 410
this was fone by first purging the old drivers

Tried installing cuda 10.0 following the instructions

Tried installing 410/396 drivers following with 10/9.2 cuda-toolkit

Tried installing with xorg stoped

tried dissabling noveau opensoure drivers

still no luck, am i missing something?

How did you install the driver/cuda?
Please run nvidia-bug-report.sh as root and attach the resulting .gz file to your post. Hovering the mouse over an existing post of yours will reveal a paperclip icon.

Cuda was installed by installing dbkg -i file and then running usual apt-get install

I tried installing drivers by

1.sudo apt-get install nvidia-driver-XXX

2…/NVIDIA-installer.run

3.sudo ubuntu-drivers autoinstall

4.By turning off the xorg and then installing with all the methods.

Since it’s an Optimus notebook, don’t use the .run installer.

  • purge anything nvidia/cuda you installed, especially the .run installer using the --uninstall option
  • uninstall bumblebee
  • use the ubuntu graphics ppa to install the latest driver, check that nvidia-prime is installed.
  • use ‘sudo prime-select nvidia’ to switch to nvidia profile
    if everything works, you can install cuda:
  • download/follow the instructions to add the .deb to your system
  • don’t install cuda
  • instead, use ‘sudo apt install cuda-toolkit-10-0’ to just install the toolkit.

The log i provided is done after these steps, no bueno, i always purge nvidia/cuda before each try.

No bumblebee on the system.

sudo prime-select nvidia

lspci -k | grep -A 2 -E "(VGA|3D)"

Please check if the file
/lib/modprobe.d/blacklist-nvidia.conf
or
/etc/modprobe.d/blacklist-nvidia.conf
exists and delete it.
Furthermore, either your dvd drive is broken or has a bad cd/dvd inserted so that the log is flooded with read errors from that. Please remove it and create a new nvidia-bug-report.log

It works after deleting
/lib/modprobe.d/blacklist-nvidia.conf

You are my hero, can you explain wtf was that all about? How that blacklist got there?

And the errors are from external hdd, don’t worry about it, it’s a workhorse.

It’s an Ubuntu bug that has been introduced with the latest nvidia-prime package update. It creates that file and then forgets about it.
