the blacklist file prevents Nouveau from loading, but if you need to double
check that it actually worked you use 'lsmod'
I pipe the output to grep to shorten the list:
$ lsmod |grep nouveau
root@ENU-2:~# lsmod | grep nouveau
root@ENU-2:~#
This will output a single line if it finds the nouveau kernel module, or do
nothing if nouveau is not loaded. Do the same for the nvidia driver:
$ lsmod |grep nvidia
root@ENU-2:~# lsmod | grep nvidia
nvidia_drm 36083 2
nvidia_modeset 1100086 3 nvidia_drm
nvidia 14351241 84 nvidia_modeset
ipmi_msghandler 37262 1 nvidia
drm_kms_helper 119698 2 i915,nvidia_drm
drm 323926 6 i915,drm_kms_helper,nvidia_drm
i2c_core 48117 7
drm,i915,i2c_i801,i2c_dev,drm_kms_helper,i2c_algo_bit,nvidia

If both drivers are loaded at the same time, you will have problems
If neither driver is loaded, you will have 2D performance only.
If nouveau is loaded, but NOT nvidia then nvidia-settings will crash and
burn.
Find which of the 2 modules you have currently loaded in your kernel with
lsmod,
Then check the nvidia packages you have installed:
$ ls /var/log/packages/ |grep nvidia
root@ENU-2:~# ls /var/log/packages | grep nvidia
nvidia-legacy390-driver-390.87-x86_64-1_SBo
nvidia-legacy390-kernel-390.87_4.4.157-x86_64-1_SBo
root@ENU-2:~#
None of the above suggestions are fixes, just triage. What is broken
depends entirely on the output of lsmod vs the nvidia programs you have
installed.
nvidia-settings runs.
/etc/X11/xorg.conf 73 lines, starting with:
# nvidia-settings: X configuration file generated by nvidia-settings
# nvidia-settings: version 390.87 (root@ENU-2) Sun Jan 6 15:29:25 PST
2019
It also has a set of lines:
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "GeForce GT 610"
EndSection
(When I saved that configuration there were two screens. In this file I
only see screen 0. Should I try running nvidia-setting again as root,
which I did the first time) and see if the changes stick?
