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