I want to install CUDA toolkit and NVIDIA drivers on Ubuntu.I am starter in linux,so I have no experience.I've had worked on this for three days but problem still exists.

Firstly, I disabled Secure Boot in BIOS.After that, In grub menu, I set nomodeset quiet splash installed CUDA Toolkit 10.1 from there.And to install Nvidia drivers I applied steps given below:

$ sudo add-apt-repository ppa:graphics-drivers/ppa  
$ sudo apt update  
$sudo apt install nvidia-driver-418  
reboot

,

when nvidia-smi is entered the output is:

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

How can I solve this, thanks friends.

  • Please edit your question and post output of the following commands: 1. `mokutil --sb-state` 2. `ls /sys/firmware/efi/` 3. `sudo lshw -c video` 4. `dkms status` 5. `lsmod | grep nvidia` and 6. `echo $XDG_SESSION_TYPE` – Marmayogi Apr 18 '19 at 19:16
  • I ve edited the outputs above, @Marmayogi thanks. for your help. What should be done friends – Denisa Apr 18 '19 at 21:02
  • Do you have any line "blacklist nvidiafb" in any file in /etc/modprobe.d ? Should be on in blacklist-framebuffer.conf. If not, something went wrong with the install, you may add it, but maybe other things are missing too. – ubfan1 Apr 18 '19 at 21:54
  • Yes, @ubfan1 **blacklist nvidiafb** exists in the file **/etc/modprobe.d/blacklist-framebuffer.conf** and it is uncommented.Also in the same path, there exists a file that contains following codelines: **blacklist nouveau** **options nouveau modeset=0** **#alias nouveau off** **#alias lbm-nouveau off** – Denisa Apr 18 '19 at 22:28
  • You tried to install nvidia-418 instead nvidiafb (framebuffer) is in the kernel. Please issue commands: 1. `sudo mv /etc/modprobe.conf /etc/modprobe.conf.bak` 2. `echo "blacklist nvidiafb" | sudo tee -a /etc/modprobe.d/nvidiafb.conf` 3. `sudo depmod -ae` and 4. `sudo update-initramfs -u`. Now install Nvidia driver 1. `sudo apt-get purge nvidia*`, 2. `sudo add-apt-repository ppa:graphics-drivers/ppa`, 3. `sudo apt update`, 4. `sudo apt install nvidia-418` and 5. finally **Reboot**. – Marmayogi Apr 19 '19 at 02:19
  • I have just edited @Marmayogi .After purge and reinstall process Blank Screen appears. – Denisa Apr 19 '19 at 16:03

  • @Denisa, please appear at chat session. `PKCS#7 signature not signed with a trusted key` is not solved yet! – Marmayogi Apr 20 '19 at 16:52
  • **sudo systemctl status systemd-modules-load** I r'ssue the command .I realized in file **/etc/modules-load.d/modules.conf** there exist a line **nouveau.IN this file I commented nouveau =>> #nouveau , save the file, dpkg --configure -a , – Denisa Apr 25 '19 at 20:10
  • apt-get dist-upgrade , apt-get -f install then reboot blank screen problem continued.Then I opened /etc/default/grub with the text editor nano, I edited theline: GRUB_CMDLINE_LINUX_DEFAULT="nvidia-drm.modeset=1" *also in this line I had removed **nomodeset quiet splash , save and exit. – Denisa Apr 25 '19 at 20:10
  • Then I run update-grub and reboot Blank screen problem is solved .But **PKCS#7 signature not signed with a trusted key. ** codelines continue appearing on my screen while I am opening the computer.I purged and removed all f'les related with cuda and nvidia\ after nvidia uninstallation the PKS#7 ... has gone/BUt after I reinstalled them again it started to appear again.Until now, it has not created any problem.Thank all of you friends! – Denisa Apr 25 '19 at 20:10
