I have recently installed (fresh) Fedora 25 and while trying to configure xrandr with the below command, it displays error:


xrandr --output WAYLAND0 --mode "1600x900_60.00"


Configure crtc 0 failed

When I tried to perform the same in Gnome on Xorg, it worked.

Please help me configuring the monitor in Wayland.

xrandr is for Xorg, hence why it's got x at the start of its name, so that's hardly surprising. I'm afraid I don't know the solution though.

You can't use the Displays option in the Gnome control center?

Nope. It doesn't recognise the actual resolution for monitor. It only has two basic resolutions.

Then wayland is not recognizing your video card or your monitor properly. I would suggest filing a bug on wayland and using the Xorg option for now.

This is well explained in this fedora wiki :

Yes, but they only state that these are the issues which are yet to be addressed. So I believe I have to wait for the updates, that's it? Or is there a workaround?!! Any suggestion for some ready alternative to xrandr?

I had just resoved this issue. Fist, you need for disable WAYLAND by uncomment in file: /etc/gdm/custom.conf


Reboot your linux.

After that, run the xrandr command you will not found WAYLAND0, you will found real card: DP1, HDMI1, VGA1, etc... instead

Now, you can use xrandr to change display resolution normally (follow the guide at here:

This does not really address the question. Also even if gdm uses wayland, it should be possible to start an usual based desktop session which is mentioned in the question.

But for the Newbie (about me), I can't find any useful way to resolve this issue. I don't understand about "how to WAYLAND work". How to use wayland with correct resolution @muep?
