How to properly switch from Wayland to X11 (temporarily)?

[xps]

Hi,

I have a two monitor setup and need to record my external screen. My setup is my laptop’s built-in 16:10 4K screen and an external Full-HD 16:9 monitor. I just installed Manjaro with Gnome and found that it’s running wayland, as simplescreenrecorder won’t work.

So, I figured that I just switch to TTY3 and run startx. But here come the problems:

• In X11 the screen resolution for both screens are set to 2x. Therefore, the external monitor’s resolution is scaled to 948x540px which is bad
• When I tried to open the settings app or gnome-terminal it didn’t show. After switching back to TTY2 and Wayland, I found that both programs were opened there.
• (On the plus side: firefox and simplescreenrecorder ran properly and the screen recording of just the external monitor worked as intended)

Which is when I stopped to try it myself and figured I better ask here, how to do it properly (to not mess up the system).

• Do I need to stop Wayland somehow or is there a possibility to log into a X11 session from GDM?
• How do I configure fractional scaling and different scalings/screen resolutions for X11 without messing up the wayland configuration (as far as that’s possible—already read that Wayland is recommended for this kind of monitor configuration). I guess, that I can manage the configuration part, once the session runs properly—I just want to make sure that I don’t mess up the (already properly configured) wayland configuration.

You can login to an X11 session from the login screen by choosing GNOME on Xorg in the bottom right.

Thanks. I was too blind

But unfortunately, I’m also not able to find the correct settings for xrandr. I played for more than an hour messing the display seetings more than once (which forced to reboot/kill x ).

I’d appreciate it, if someone could help me figure out the correct xrandr command to have the built-in monitor at 1.5x (of it’s native 3840x2400) and the external monitor at 1x (1920x1080) at the left of the built-in monitor…
