Where does nvidia.conf go?

[VanessaDeagan]

Hi. I tried Kubuntu a while ago, then switched over to Manjaro, and am now back to Kubuntu (currently running 17.04).

What I'd like to know is - where does the "nvidia.conf" file go? In Manjaro, if you saved it in /etc/X11/mhwd.d/nvidia.conf, then it would be loaded on each and every system boot.

Where should I put my nvidia.conf file in Kubuntu?

What's in it?

*buntu's use /etc/X11/xorg.conf.d/

to store config files that replicate the old xorg.conf sections if that's what you're looking for. I have a "device.conf" file:

[FONT=monospace][COLOR=#000000]Section "Device"[/COLOR]
    Identifier  "device0"
    Driver  "nvidia"
    VendorName  "nVidia Corporation"  
    BoardName "GeForce GTX 780"
    Option  "UseEvents"  "false"
    Option  "Coolbits" "12"
    Option  "TripleBuffer" "True"
#                + Enables triple buffering. "Decreases the time an application stalls while waiting for vblank events, but increases latency slightly" (NVIDIA Readme)

And, why do you have to put it anywhere? When I installed nvidia-378.13 to drive my GT650M the installation process took care of all of that. It made my secondary nvidia GPU, which cannot be made primary in the BIOS, behave like the primary GPU, controlled by systemd.

Here is where mine is:

$ locate nvidia.conf
/usr/share/lightdm/lightdm.conf.d/90-nvidia.conf

$ cat /usr/share/lightdm/lightdm.conf.d/90-nvidia.conf
[SeatDefaults]
# Force using traditional X
type=xlocal
# Scripts to handle PRIME
display-setup-script=/sbin/prime-offload
display-stopped-script=/sbin/prime-switch

But, all of that is meaningless for me because Neon uses sddm, not lightdm.

Because I need to set my PowerMizer defaults and set Coolbits.

I just checked again, and it looks like my

/etc/X11/xorg.conf

contains my nVidia settings.

did you edit this file ,,,or did it have the settings you like by default ,,,,I cant imagine it had any "coolbits" settings in it by default.

this file can get reset to defaults during upgrades ,,, that is unless you have your own settings in /etc/X11/xorg.conf.d/20-nvidia.conf ,,,then this will be used and added to the default in
/etc/X11/xorg.conf

That was an interesting link, Vanessa, thanks!

My Acer V3-771G seems to love its secondary Nvidia GT650M using nvidia-378.13. The powermizer works automatically, which is why I was wondering why you needed to control yours. Stupid assumption. I'm not brave enough to play with CoolBits.
