I’ve struggled a lot with messing with the conf files in /usr/share/X11/xorg.conf.d/ quite a bit, but one change I’d very much like to make to my system is changing my monitors pre-login, since my monitors show in 1920x1080, 640x350, 640x350 with the last one seeming to be primary at the time. How do I set my monitor’s display in a conf file? I assume I need to use modeline, but last time I attempted that I lost a graphical display. Here’s my system info from inxi --admin --verbosity=7 --filter --no-host --width:

im not sure what exactly do you want to do… also you didnt mentioned what desktop are you using and what is the display manager …
Ah, my apologies. My goal is to have my resolution changed before my login. As of this moment, my login screen is always the resolution of a fresh Manjaro install. I believe xrandr/xorg things can fix it, but I don’t understand enough of it to solve this. If I understand correctly, I need to make a file called 10-monitors.conf? My system info:
OS: Manjaro Linux x86_64
Kernel: 5.15.38-1-MANJARO
DE: Plasma 5.24.5
CPU: Intel i7-4790K (8) @ 4.400GHz
GPU: NVIDIA GeForce GTX 1070 Ti
GPU: Intel HD Graphics
Display Manager? It’s X11, if that is a display manager.
i still dont understand what you mean …what is your current resolution and to what do you want to change it
provide output from:
inxi -xxS
System:
Host: NaginiBox Kernel: 5.15.38-1-MANJARO arch: x86_64 bits: 64
compiler: gcc v: 11.2.0 Desktop: KDE Plasma v: 5.24.5 tk: Qt v: 5.15.3
wm: kwin_x11 dm: SDDM Distro: Manjaro Linux base: Arch Linux
When I’m on my desktop, my resolution is 1920x1080 (primary), 1024x768, 1024x768. When I boot my computer, and hit my login screen, my resolution is 1920x1080, 640x350, 640x350 (primary?). It is gross.
so your login screen resolution is different then your resolution after you log in?
so your resolution gets normal after you enter your password?
Yes. I don’t like the look of my displays when I am at my login, so I wish to change it
Research has brought me to the point where I believe this is close to the solution, but I still don’t quite understand. Modeline is full of numbers I don’t understand the purpose of. Here’s a 10-monitors.conf I quickly made, with editorial question marks. I don’t know how to use Modeline without destroying my Graphical Interface. I don’t know if PreferredMode modes what I need. I also do not know if I can just place this in /usr/share/X11/xorg.conf.d/ or if Manjaro uses a different file for conf

ok i dont know how to set it up, i thouth you wanted to do something else… and do you need to have the login at startup, i have it disabled…
I suppose doing that would be an easy and surefire fix. It’s a bit of a basic security risk, but I’ll consider it
you could try this:
go to /etc/mkinitcpio.conf and edit the modules section to look like this:
MODULES=(i915)
if there are already some modules ad the i915 to them, dont remove any of them
then run this:
sudo mkinitcpio -P
reboot and check if you have normal resolution
That does not appear to have solved it. Should I change it back?
yes, change it back, i thought early loading of the graphic driver might help…
It is purely calculated. You do it like this:
cvt 1024 768
Then just copy&paste it. However this normally not needed if xorg detects the correct modline itself.
What do you mean by that? Just put it in the Modeline part, like this:
Section "Monitor"
Identifier "DP-4"
Option "Primary" "true"
EndSection
Section "Monitor"
Identifier "HDMI-0"
Modeline "1024x768" cvt 1024 768
Option "PreferredMode" "1024x768"
Option "RightOf" "DP-4"
EndSection
Section "Monitor"
Identifier "DVI-D-0"
Modeline "1024x768" cvt 1024 768
Option "PreferredMode" "1024x768"
Option "RightOf" "HDMI-0"
EndSection
Also, if I just put the file 10-monitors.conf into /usr/share/X11/xorg.conf.d and reboot it should configure my monitors pre-login, right?
ModeLine "name" mode-description
This entry is a more compact version of the Mode entry, and it also can be used to specify video modes for the monitor. This is a
single line format for specifying video modes. In most cases this isn't necessary because the built-in set of VESA standard modes
will be sufficient.
man xorg.conf
cvt is command on the terminal which prints the modeline. Alsoupper and lowercase is important, so it ModeLine and not Modeline
yes
Thanks for the help! So, as a final check, this won’t cause me any problem, right?
