external Display should be the only Screen (Login + Work) [Solved]

[chrissi55]

I am new to MX Linux - started with the 23.6.1_KDE version and i'm using kernel 6.14.
I have it installed on a Notebook and an external Monitor is connected via HDMi.

My purpose is to have the internal Display is disabled (--off) on Login Screen so the external Display is the only one active during login and during sessions.

I found several pages with hints and help, tried to figure it out what is wrong in my case.

The command xrandr | grep -w connected delivers

Code: Select all

XWAYLAND0 connected 1920x1080+3200+0 (normal left inverted right x axis y axis) 290mm x 170mm
XWAYLAND1 connected primary 3200x1800+0+0 (normal left inverted right x axis y axis) 700mm x 390mm

With that information i did the following, edited the file /usr/share/sddm/scripts/Xsetup as follows:

Code: Select all

#!/bin/sh
# Xsetup - run as root before the login dialog appears 
xrandr --output XWAYLAND1 --primary --auto
xrandr --output XWAYLAND0 --off
exit 0

The external display has a higher resolution so it is XWAYLAND1.

My question, does .../sddm/scripts/Xsetup only work with X11 (Xorg) or does it also should work with wayland as well?
If not, what steps / settings do i have to edit, to make my external monitor to be the "king in the game"?

At Login prompt the focus is still always on XWAYLAND0 (cursor blinking in password field on the internal display)

Thanks for your help, hope my infos are sufficient.

Hve you tried turning the internal display off in the bios? That way as soon as it boots, it will turn off the internal display and you should see the boot process on the extrenal display.

[i_ri]

does focus follow mouse?

[chrissi55]

The BIOS is rather old, and there is no option to turn the notebook display --off.

What do you mean by "does the focus follows mouse"?
When klicking by mouse into the password field on the external display i get the cursor there, yes if that's what you think of.

Under another Linux environment with gnome and greeter was gdm3 it was possible to do the following to reach the purpose
1) make changes under X11 with the gui for display, resolution, etc.
2) sudo cp ~/.config/monitors.xml ~gdm/.config/monitors.xml
(to copy over the personal settings to the global settings and make them valid for boot time as well)
3) sudo chown gdm:gdm ~gdm/.config/monitors.xml

After a reboot the internal monitor (display) is black and the external display only shows login screen and had the focus.

I need some similar with sddm as greeter for the wayland display manager.

For the moment i activated both displays in the gui and told the system to have the external display as "primary".
With Super + P i can switch usually between "only external" -> "only internal" -> "both" -> and "extend display to right/left"

I'm not familiar with KDE, but does it have - or anything similar to - "MX-Tweak" and/or "Display"?

If so, this may work, check post #'s 5 & 7.

Cheers!

[chrissi55]

Thank you for the tip.

I checked MX-Tweaks from the MX Tools and have in my system the following register cards





I think there is missing some tweaks / settings maybe?

Code: Select all

Interesting (but not part of this topic!) is that MX Tweak seems not to show all settings taht have been made in my case ...

For my Oracle Virtualbox it was nescessary to disable the KVM at boot time. See the output of the Snapshot tool 
GRUB options = kvm.enable_virt_at_load=0 quiet splash

But the tag beneath "Disable early KVM module ..." is not set although i think this is the corresponding GUI setting for the GRUB option i have set in /etc/default/grub manually ....

weird, isn't it?

[MXRobo]

First, I don't know if I referenced would affect the primary LOGIN screen.


Searched: linux kde how to make external monitor primary screen

https://ao.vern.cc/exchange/askubuntu.c ... 57eccbde40

Settings --> Display and Monitor --> Display Configuration

So maybe KDE's "Display and Monitor" is similar to Xfce's Display

I don't know KDE or linux really.

Good luck!

[chrissi55]

OK you are right -> renamed the title of the thread in "external Display should be the only Screen (Login + Work)"

That's exactly what i want - after pre-boot the dispaly should only be seen on the external monitor. For Login and later for work. The internal monitor should switch to blach ( --off)
That what you propose i already have been made, see Post #6

For the moment i activated both displays in the gui and told the system to have the external display as "primary".
With Super + P i can switch usually between "only external" -> "only internal" -> "both" -> and "extend display to right/left"

My purpose is to set the internal Notebook Display to -off when Login Screen appears.
There is definitely no BIOS option to do that - i think this makes sense because, if i would plug out the external monitor it should be possible to reach the desktop in any way.
As long as the external monitor is pluged in MX Linux should do the "Super + P" -> choice "only external Monitor" each boot automatically.

I hope i could give some clarification for my problem that every boot both displays are on and only the internal monitor has the focus for the login screen. After login -> both displays resist on but then the external monitor gets the focus and becomes "primary" (too late for my purpose) but also the internal monitor is still activated but should be deactivated.

I maybe mistaken, but i think i could not reach my purpose by GUI there must be a setting made by konsole/terminal in any *.conf file or something like that?
