I attempted to install CUDA 10 on Ubuntu 18.04 using the official Nvidia repository. This downgraded the nvidia driver version to 418. After rebooting I only got a black screen, and I had to purge the repository and re-install nvidia-driver-435 in order to get a working display again.
The following errors were printed on dmesg:
Sep 11 21:27:39 al-desktop kernel: [ 800.054852] NVRM: RmInitAdapter failed! (0x26:0x65:1106)
Sep 11 21:27:39 al-desktop kernel: [ 800.054921] NVRM: rm_init_adapter failed for device bearing minor number 0
This error was repeated over and over until I purged the 418 driver.
Does this driver version even support my 2070 super?
