Hello Forum,

I am trying to use RTX 4070 in my Ubuntu 20.04 computer. I have installed the driver 535 for my RTX 4070 graphical card. However, after I installed the driver, I cannot use the graphic interface and I can only use the computer through tty. Also nvidia-smi shows that cannot find any devices.

I have attached the bug report. Any help will be appreciated!

Thanks.

Hi there @bai12wp1 and welcome to the NVIDIA developer forums.

Looking at your log you have residual files from three different driver versions conflicting:

Please start from a fresh driver installation. That means

  • booting into tty
  • making sure no NVIDIA kernel modules are loaded
  • Purge ALL NVIDIA drivers from your system
  • REBOOT!
  • Install the latest driver, preferably through the normal Ubuntu distribution methods as was stated during the manual installation you did:

The NVIDIA driver provided by Ubuntu can be installed by launching the “Software & Updates” application, and by selecting the NVIDIA driver from the “Additional Drivers” tab.

After that everything should work nicely.

Thanks.
