Screen resolution change with projector connected through HDMI messing with touchscreen input

Ask Fedora
1

Hi,

First of all I have to admit that I’m fairly new to Linux and I try to slowly get the hang of it. Most tasks I have to do on Linux work just fine or even better than with Windows 11. But I have one major problem on my daily job I can’t figure out for the life of me.

I’m using a Thinkpad X1 Yoga with Fedora 40 and I’m experiencing a problem when I connect this computer to a projector through a HDMI cable.

My normal screen resolution is 16:10 (1920x1200) but as soon as I connect the cable it switches to 16:9 (1920x1080). I did not experience this problem with W11 so I guess the projector is not the problem. The option for 16:10 dissapears from the menu in the settings.

This wouldn’t be a problem so far but my touchscreen and my pen input are not accurate anymore. For example when I write on the bottom of the screen, my writing is shifted to the center of the screen by quiet a margin and vice versa when I write on the top part of the (touch)screen. Only in the middle the input appears where it should.

I was looking for a way to prevent the automatic change to 16:9 or a way to adjust the touchscreen accordingly. I already changed the resolution of the projector to 16:10 (1920x1200) but to no avail.

I hope I explained my problem well enough.

Any help would be greatly appreciated!

Have a nice day and thank you in advance for your help
