Add and set custom screensize in Wayland

[peer]

When I am using Xorg I can add an set a custom screensize with xrandr. This works in every DE (
kde, xfce, gnome,....).
I cannot find a solution to do the same in Wayland

Is there way in Wayland to add a new (custom) screensize and to set this screensize for every DE??

Have you tried the traditional method, /etc/X11/xorg.conf.d/50-monitor.conf:

Code: Select all

Section "Monitor"
    Identifier	"Monitor0"
    DisplaySize	378 284
    Option	"PreferredMode"	"1792x1344"
EndSection

PreferredMode determines the resolution; DisplaySize, in conjunction with the resolution, the DPI. At least, that's how it had to be done before xrandr came along.

The qeustion is about Wayland, not X11
At this moment I added the preferred custom screen size to grub and that works both for X11 and Wayland
In X11 I can create a script with xrandr to add and set a custom screen size. I would to create a similar script in Wayland.

Wayland depends on an X foundation to run. Run ps -A while a Wayland session is running to see what else is running. See what happens to Wayland if you try to remove Xorg/X11 packages.

X11 is a protocol, Xorg is a program that implements this protocol. Wayland is a protocol, gnome-shell is one program that implements this protocol. There is no "Wayland" program.

As far as I know, there is no standard feature in the wayland protocol that lets you control the monitor resolution but many wayland implementations support extensions that allow you to do this. So for now you need to use the extension/tool that supports the wayland implentation that you use.

As far as I know this is untrue. You can run gnome-shell completely without support for xwayland.

So, don't run the tests; don't try get what you asked for. I have no expectation of ever having gnome-shell installed.

Do you try wlr-randr?

[peer]

I will look into wlr-randr

After installing in 'Debian stable kde wayland' I run the command lwr-randr and got the following error:

Code: Select all

wlr-randr
compositor doesn't support wlr-output-management-unstable-v1

So it looks wlr-randr does not work in my os.

wlr-randr works with wayland implementations using wlroots. Google suggests that with KDE you could use kscreen-doctor.

I have seen kscreen-doctor (should work for KDE) but ! was looking for a solution that is independant of the DE.
I guess it there isn't an independant solution for wayland at this time.
Let's close this item for now.
Thanks for the suggestions

What about wdisplay??

[peer]

does not work either (and it is graphical)
error: "compositor does not support wlr-output-management-unstable-v1"
