How to change the display resolution on logon screen / greeter?

Hello at the community,
how or better in which script can I change the resolution of the screen for the greeter on my notebook? Grub is fullscreen and I have changed the resolution on desktop with arandr and had make it stable with an autostart-script. But I dont't know, how it's to change on logon/greeter-screen. My native resolution is 1280x800 and the resolution on start of the greeter is much smaller. (800x600?) Someone of you can help me, I'm sure.

thanx to all

I think this guide might be helpful. If you wish to change the LightDM login screen resolution, just follow the steps there.

@Kim Jong-un Stunt Double
Thanx for your answer. But, unfortantly, it doesn't work. I've tried it, but I think lightdm.conf and usr/share/lightdmxrandr.sh is'nt active, until you are logged in. It takes only effect on the desk-resolution. But it is the resolution of the logon-screen, which is wrong. Right script on wrong place - I think so.

^Ok, I see. If you open /etc/lightdm/lightdm.conf as root and uncomment the display-setup-script line (around line 69) and use there

display-setup-script=xrandr -s 1280x800

and save it. Does it work after a reboot?

Re: How to change the display resolution on logon screen / greeter?

I think the best option here is an Xorg configuration file.

These commands will create a file at /etc/X11/xorg.conf.d/00-resolution.conf with the configuration you need:

sudo mkdir -p /etc/X11/xorg.conf.d
sudo tee /etc/X11/xorg.conf.d/00-resolution.conf <<!
Section "Screen"
    Identifier "Screen0"
    Monitor "VGA1"
    DefaultDepth 24
    SubSection "Display"
        Modes "1280x800_60.00"
    EndSubSection
EndSection
!

You will probably have to change the Monitor line (and perhaps tweak the Modes as well) — run the `xrandr` command in a terminal, check which display is described as "connected" and substitute the correct values in.

Re: How to change the display resolution on logon screen / greeter?

jumper1968, do you have the right resolution with grub? sure?
and what do you mean by "much smaller"? the lightdm greeter doesn't fill the whole screen? or it does fill the whole screen but looks washed out because of too-low resolution?

in any case, i think we need some facts.

lspci -k

output, please.

Re: How to change the display resolution on logon screen / greeter?

Hello,
thanx @ all! I've changed the lightdm-gtk-greeter.conf in the first line, nearly like martix ;-) showed in his link. It works, but only if it placed in the first line of seat[0].
That's it! The background picture isn't shown at this way, but that's no problem for me. ;-)
Thank you @ all.
Can be closed....for me. ;-)
