MATE First use of sudo in terminal slow

[GilbertDube]

The first sudo command (only the first one) take ~25s to execute. PC usage stay at 2% ex: sudo caja or: sudo xed /etc/fstab Afterward any command will execute fast. Did not see that behavior in Cinnamon (VM)

Added this Auth.log capture of when it happen.

I can't reproduce this on LM20 MATE. Was this a one-off issue for you or can you reproduce it? Can you add some detail to when exactly the issue happens (e.g., first time after log in, every time you open a new terminal in the same log in, or ...).

Note also that you should probably not be using sudo with GUI programs. Instead use what polkit provides to doing administrative tasks. E.g. run pkexec caja to run Caja as root and run xed admin:///etc/fstab to edit /etc/fstab as root.

Hi xenopeek, thank you for your time.

The problem appears every time I restart, but only the first time I enter an command inside a terminal. All subsequent command are normal.

I reinstalled several times and tested all day. I found this in my startup script:

nvidia-settings -a [gpu: 0] / GPUFanControlState = 1 -a [fan-0] / GPUTargetFanSpeed = 65

when I remove it, I have no more delay, when I put it back, the problem reappears.

I have the 440.64 NVIDIA driver installed. My xorg.conf:
