Can't get a higher resolution on fedora

randuser · 10-08-2023, 05:08 AM

I installed the Fedora 39 beta on my Lenovo ThinkPad X280 i5-8250U 1080p Laptop but in the settings app and on the command line the screen resolution of my built-in display is shown as 1366x768 with a frame rate of ~ 60 Hz.

Code:

$ xrandr | less
Screen 0: minimum 16 x 16, current 1366 x 768, maximum 32767 x 32767
eDP-1 connected primary 1366x768+0+0 (normal left inverted right x axis y axis) 280mm x 160mm
   1366x768      59.98*+

```

My laptop is: https://www.amazon.co.uk/gp/product/...?ie=UTF8&psc=1

What could be causing fedora not to detect the correct screen resolution of 1080p and how can I get fedora to detect the correct resolution?

Welcome to LQ!

You don't say if you are running X11 or wayland. Maybe try the alternative?

Also, please remember that you are running fedora 39 which is still in beta. So, maybe you would find better advice if posting your question at:

Thanks for the link. I'm on wayland. I've tried with x11 and the highest resolution is still `1366x768`.

May be Fedora is currently detecting and using a default resolution of 1366x768 for your Lenovo ThinkPad X280's built-in display. To correct this and set the desired resolution of 1080p, you can use the following steps:

Check Available Resolutions:
Run the following command to view the available resolutions:

bash
Copy code
xrandr
Look for the entry corresponding to your built-in display (e.g., eDP-1) and note the available resolutions.

Set Resolution:
Use the following command to set the desired resolution:

bash
Copy code
xrandr --output eDP-1 --mode 1920x1080
Replace 1920x1080 with the correct resolution if it's different.

Permanent Configuration:
If the resolution change is successful, you can make it permanent by adding the command to your user's startup applications.

For example, on GNOME, you can use the "Startup Applications" app to add a new startup command.

By following these steps, you should be able to set and maintain the correct resolution for your Fedora installation on the Lenovo ThinkPad X280.
