How to find display configuration

Post by psiphre »

I have been trying unsuccessfully for over a week to get a display setup working and so far mint is doing the absolute best job. i want to keep fiddling with it but i need to know what file it is that makes my displays display the way they are displaying.

is it something in /usr/share/X11/xorg.conf.d? is it something in /etc/X11? is it something else?

mint automatically configured my displays in such a way that they "basically just work". i had to fiddle with enabling and disabling a few of them several times before it figured out everything perfectly, and i had to use arandr to do the layout since the display control panel is rainbows. but now that i've got them all arranged in the right way, i want to use the proprietary nvidia driver to push the one that i'm going to be putting graphically intense stuff on - or at least get some hardware acceleration out of nouveau (i got a glmark2 score of 59 on a gtx 1060 so i'm pretty sure it's not being accelerated).

so be concise: is there a file somewhere that i can edit to change the way the monitors are set up when the computer boots? if so, where is it? if not, how do i go about that?

where is the display configuration file?

Post by psiphre »

where does mint keep the file that tells the OS how to set up the displays? i've been beating my head against getting my whole setup working under linux since i made the jump on the first and i need to be able to know that if i make a change to "file X", it will be represented in the display layout.

sorry, i know now that this is a repost, i didn't realize when i posted the original that it had to be authorized by a moderator :lol:

It isn't really clear to me what you are trying to do and you did not share any system information despite the huge red banner at the top explaining "how to get help", so I'll just take a wild guess and say ~/.config/monitors.xml.

There's no one file like that really, and there's no useful system info there that could be used to say what may be done. Post the text output of inxi -Fxz run in the terminal.

And what problem are you trying to solve here?

output of inxi -Fxz below. as you can see, i have two video cards, a 1060 on bus ID 01:00 and a quadro on bus ID 02:00. i have four monitors plugged in to the quadro and one plugged in to the 1060. currently they are both being driven by the nouveau driver, which sucks. i'd like to use the official driver, but when i do, only the monitors plugged in to the 1060 work.

ultimately i think my goal here is to pass the 1060 through to a kvm windows machine so i can play my games, while getting just a bit better performance from the quadro cards so i can i.e. play a video without atrocious artefacting.

Personally I don't have experience with Nvidia's linux driver, yet your issue seems to be about configuring said driver, so I do not feel qualified to answer.

Adjusting the thread title to better describe the problem may help in getting the right people into the thread.
