It can not use nvidia-settings to switch from the power saving mode to the performance mode
I try to use nvidia-settings 410.73-0ubuntu0~gpu18.04.1 with
nvidia-graphics-drivers-410 410.73-0ubuntu0~gpu18.04.1 in
ppa:graphics-drivers/ppa to switch from the power saving mode to the
performance mode on Ubuntu 18.04.
But it failed.
ERROR: NVIDIA driver is not loaded
ERROR: Unable to load info from any available system
However `prime-select nvidia` still works fine and there is no such issue
by nvidia-settings 390.77-0ubuntu0.18.04.1 in bionic-updates.
I also opened https://bugs.launchpad.net/bugs/1800413 to track this issue.
