I use proprietary NVidia driver and I want to setup brightens, contrast and gamma using NVIDIA control panel. The setup parameters are properly stored in ~/.nvidia-settings-rc file. But when KDE starts, parameters are not apply to the picture shown on display.
So i run

Code: Select all: nvidia-settings

parameters are properly appalled but control panel window appears on screen.
So I try only to load parameters without calling control panel window, but an error is rapported and parameters are not apply to the screen.

Code: Select all: [maciek@piotr ~]$ nvidia-settings -l Gtk-Message: Failed to load module "canberra-gtk-module"

So my question is. How can I start user KDE session with applying setup parameters stored in ~/.nvidia-settings-rc ?

Check the man page:

man nvidia-settings wrote: -l, --load-config-only
Load the configuration file, send the values specified therein to the X server, and exit. This mode of operation is useful to place in
your xinitrc file, for example.

Yep, but it does not work. As I wrote i try:

Code: Select all: [maciek@piotr ~]$ nvidia-settings -l Gtk-Message: Failed to load module "canberra-gtk-module"

And nothing changed

my workaround is to define such script:

Code: Select all: #!/bin/bash nvidia-settings& sleep 3 killall nvidia-settings

And run it before KDE start, using System Settings -> Start and stop session -> Autorun -> Add script (it is translation from my language to English)

That is not related to nvidia-settings nor is it an error, only an informational message.
Check e.g. viewtopic.php?p=27034#p27034 and the following post for the solution for that.

What would be interesting would be to run nvidia-settings -q all > test1, then nvidia-settings -l and afterwards nvidia-settings -q all > test2
Then diff -u test1 test2 and see if there are differences, besides maybe different temperature readings.

Otherwise you should ask that in the relevant nvidia forum: https://devtalk.nvidia.com/default/board/98/

Its a kind of mystery. In some Linux distros nvidia-settings works properly, in others - no.
At this moment I use workaround script. It resolve a problem in everyday use. But of course it is not bug fixing.

Please mark the thread accordingly by editing the topic of the first post and prefix it by [DONE], thanks

So You have!

Code: Select all: #!/bin/bash # # This is a bash shell script to be run at startup # nvidia-settings --load-config-only

He said that didn't work, proposed before already: viewtopic.php?p=38898#p38898

OK. I didn't realize that nvidia-settings -l was the same as nvidia-settings --load-config-only
