Limited screen resolution - intel HD Graphics 530

Just continuing where I left in the old forum (Limited screen resolution - intel HD Graphics 530 - Newbie Corner - Manjaro Linux Forum).

So I installed " arandr " and I can see a small interface. How do I now set the desired screen parameters?

I tried with:

$ sudo arandr --newmode "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync
Usage: arandr [savedfile]

arandr: error: no such option: --newmode 

But apparently this is not the way to use it…

Hope anyone can help
Thank you

xrandr command has a --newmode switch - perhaps you meant to use that one?
Also see the arch wiki.

Just because I assumed arandr is similar to xrandr which they probably are but I lack the experience to understand exactly how.
I already tried to use xrandr to increase my screen resolution from 1280x768 to 1680x1050 (using the --newmode switch) without success until @Shjim suggested to try arandr but it seems I cannot do much from arandr menu. How can I force/set 1680x1050?
I will have a look at the wiki in the meantime, thank you!!

Edit: the wiki describes exactly what I did or tried to do with xrandr (see the archived post)

arandr is a GUI for settings display layout and some other settings. as @freggel.doe mentioned, you look for xrandr to add custom resolutions.

In the old forum you were running xrandr with “sudo”. Do NOT run this as super user.
Just xrandr --newmode "1680x1050_60.00" 146.25 1680 1784 1960 2240 1050 1053 1059 1089 -hsync +vsync
The follow the arch wiki with the next instructions

I think I used it first without sudo and the result was the same. I’ll try again and report back to you. Thanks

Same result:

$ xrandr --newmode "1680x1050_60.00"  146.25  1680 1784 1960 2240  1050 1053 1059 1089 -hsync +vsync
xrandr: Failed to get size of gamma for output default

Is it anything wrong in the line? What else can I do?

try to continue with --addmode and --output as in arch wiki.
Please post output of xrandr

xrandr --addmode default 1680x1050_60.00
xrandr: Failed to get size of gamma for output default
xrandr: cannot find mode "1680x1050_60.00"

xrandr --output default --mode 1680x1050_60.00
xrandr: cannot find mode 1680x1050_60.00

I suppose if a new mode cannot be set it neither can be found and added. Is it possible there is something wrong with the format I am writing the instructions as the wiki suggests?

The reason a used sudo is because the was one time I succeeded to add a new mode. I could see it listed in the screen settings. I am not so sure now it was sudo that made it possible.

What do you mean?

Type “xrandr” in the terminal and copy/paste the output text here

   [man@man-b150md3h ~]$ xrandr
    xrandr: Failed to get size of gamma for output default
    Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768
    default connected primary 1024x768+0+0 0mm x 0mm
       1024x768       0.00* 
       800x600        0.00  
       640x480        0.00

And yet on win 10 I can go all the way to 2048x1152…

Is there any other way to force a higher resolution than 1024x768?
