Error parsing nvidia-settings lines[i] is undefined

Asked by lee on 2020-02-03

have ubuntu 18.04.3, nvidia 440, cuda 10.2, 2080 ti gpu
worked well for a few days and then received error
"Error parsing nvidia-settings lines[i] is undefined"
nvidia smi
command not found, where it was before,
have seen similar errors reported, some suggested backing down to
18.04
Nouveau is not running
lsmod | grep nvidia shows
i2c_nvidia_gpu
lsmod | grep nouveau shows nothing
nvidia-settings shows
error: nvidia driver is not loaded
as for secure boot
secure boot is set to other, which I believe turns secure boot off
what should I do?

Seems to be known. Add that you are affected by the bug and progress there

What is the output of:

uname -a; lsb_release -a

Thanks

nvidia-drivers devices
 showed driver verisions 430, 435
where I had loaded 440, not sure why they are there
in the nvidia-settings gui I chose 435, and majic occurred
now nvidia-smi shows driver version 435.21
cuda version 10.1
Seems to be good, any thoughts?

What is the output of the command I gave, please?

yes I had seen that but the comment only the distro is supported was to cryptic for me to pick up on
