Can't achieve maximum screen resolution: BadMatch error when attempting to add new mode in xrandr

I am having trouble with getting my monitor’s maximum resolution (1920x1080) to run on Manjaro. On Wayland the option in settings to switch resolution is not there, it is simply stuck on 1366x768 (16:9). On X11, I can switch resolutions but only between 1366x768 and lower options, down to 800x600. My computer model is HP Elitebook 850 G3.

I’ve reinstalled the linux-video driver and after looking through some threads of similar problems attempted to add a new mode under xrandr:

cvt 1920 1080 60


# 1920x8080 60 Hz
modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 

and executing:

xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr --addmode eDP1 1920x1080_60.00 

gives me the error:

 X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  140 (RANDR)
  Minor opcode of failed request:  18 (RRAddOutputMode)
  Serial number of failed request:  39
  Current serial number in output stream:  40

How can I fix this?
Let me know if you need any additional information.
Thanks in advance!

:+1: Welcome to Manjaro! :+1:

  1. Please read this:
    How to provide good information
    and post some more information so we can see what’s really going on. Now we know the symptom of the disease, but we need some more probing to know where the origin lies… :grin:
  2. An inxi --admin --verbosity=7 --filter --no-host --width would be the minimum required information… (Personally Identifiable Information like serial numbers and MAC addresses will be filtered out by the above command)
    Also, please copy-paste that output in-between 3 backticks ``` at the beginning and end of the code/text.
  3. the output to xrandr and the technical specifications of your monitor will be helpful as well because the information you’ve provided points to your Monitor / PC combo not being compatible for FHD.


I checked the computer specs out and it turns out that this model only has a 1366x768 monitor after all. I should have checked more carefully before-hand.
Thanks anyway! :slight_smile:

That was my first guess, and why I requested the additional information…
