It is possible to use 2560x1080 resolution on Linux using ATI Radeon?

Hi guys, I’m new to Linux.
I’m really enjoying Manjaro XFCE, life has changed completely.


What should I do to make the 2560x1080 resolution option appear on display settings in Manjaro XFCE Minimal?

In addition to the updates on Pamac after installing Manjaro do I need to do anything else? Do I need to install anything that doesn’t come with Manjaro? If so, how do I do this?


  • LG Ultrawide 25 monitor (I use only the monitor screen)
  • ASUS N53ta Laptop - ATI Radeon® HD 6720G2 Graphics with 2GB DDR3 VRAM

Approaches I’ve tried and failed

  • Setting a new mode via xrandr
  • I tried to look for a driver on the AMD website but found nothing that appears to be compatible.
  • I tried to change the Kernel version to 4.19 and boot but it didn’t change anything.


I used to plug the monitor into the laptop (hdmi) and in Windows 10 it automatically displayed the desired resolution 2560x1080 (21: 9)

After installing the Manjaro XFCE Minimal when I plug in the monitor, the highest resolution that appears to me is 1920x1080

What do you need? Whats missing?

Dont do that. Besides this being a generally bad idea for handling any software in linux (we use repositories and packages and such … and they usually are tied to things like system libraries)… manjaro also has MSM/mhwd to handle these things. Dont deviate from that unless you have a good reason and know what you are doing.

Please see this:

Thanks for your answer!

I want to use 2560 x 1080 resolution on my monitor, but it does not appear in the display configuration menu. I’ve tried the approaches mentioned above but nothing has worked.

Sorry. I edited the first post.

I notice the 2 video cards… which is interesting … but I’m not entirely sure its down to your gpu(s) and/or drivers.

When you said

I guess that means you’ve done this:

Thanks for answering.

Yes. That’s exactly what I tried to do.
But when I apply the new mode, the monitor screen goes black.

I don’t know if it is related, but one of the LEDs on my notebook’s panel is continuos in blue color, which means it is only using the integrated GPU. And not the dedicated one.

Wouldn’t using the dedicated card have anything to do with this issue?

I installed Manjaro XFCE and updated everything on Pamac.

In hardware configurations, “video-linux” is installed and active, despite showing “video-modesetting” and “video-vesa” (not installed)

Should I install any more drivers? Where can I get it? How to install?

Hello guys

I still haven’t been able to make the 2560 x 1080 resolution work on Manjaro XFCE.

As I said above all the drivers seem to be installed and updated.

I’ve tried to add and apply via xrandr but it doesn’t work. When I apply the new mode, the LG 25 monitor screen loses its signal.

Could you help me try to resolve this issue? Or indicate an article about it?

Maybe take a look through this thread…

The answer there was basically some sort of bad configuration/driver … after a reinstall and such it worked.

Note - Towards the end is a script, but it was made for KDE (using kscreen-doctor).
