My mid life crisis nostalgic box

@beldar

This works for me as @SUBSTRING suggested editing xinitrc

Sources: https://wiki.archlinux.org/index.php/Xrandr

ssh into box, then do the following:

cp /etc/X11/xinit/xinitrc ~/.xinitrc

It will copy ~/.xinitrc to /recalbox/share/system (/recalbox/share/system/.xinitrc)

From there you can edit it with vi/nano from ssh, or use winscp/filezilla to edit /recalbox/share/system/.xinitrc

add this to the file: (1080p as an example)
xrandr -s 1920x1080

Note if you intend to use nano you may need to export the environment variable first with:

export TERM=xterm
nano /recalbox/share/system/.xinitrc

I have linked my working .xinitrc to force 720p:

.xinitrc recalbox

@substring

Thanks, done.

Change display resolution on x86 x86_64

@ash1390

It may be that xorg is not autodetecting the correct resolution of your 2nd display. You can use xrandr to duplicate the image or set a specific resolution on the vga port.

Common display names are:
LVDS - Laptop Screen
HDMI - High-Definition Multimedia Interface
DVI - Digital Visual Interface
DP - DisplayPort
VGA - Video Graphics Array
TV - Composite Video
S-video - S-Video

Get root access: https://github.com/recalbox/recalbox-os/wiki/Root-access-on-terminal-(EN)

run xrandr from terminal to see what your displays are: (my example laptop)

~ $ xrandr

VGA-0 connected 1280x1024+0+0 (normal left inverted right x axis y axis) 340mm x 270mm
1280x1024 75.02+ 60.02 

1024x768 75.03 70.07 60.00 

800x600 75.00 72.19 60.32 56.25 

640x480 75.00 72.81 59.94 

LVDS-0 connected primary 1440x900+0+0 (normal left inverted right x axis y axis) 367mm x 230mm
1440x900 59.94+
HDMI-0 disconnected (normal left inverted right x axis y axis)

Once you know what your display names are you can use xrandr to set your display.
See the example displays I used with my laptop with a monitor connected via VGA, your display name may be different.

xrandr --output LVDS-0 --auto --output VGA-0 --auto --same-as LVDS-0 (this will duplicate the same resolution on the VGA port)

To set a specific resolution on the vga port (eg: 720 resolution)
xrandr --output VGA-0 --mode 1280x720

A more complete command that will duplicate the display and set set VGA to 720:
xrandr --output VGA-0 --mode 1280x720 --same-as LVDS-0

You could also switch off the laptops display if you want:
xrandr --output LVDS-0 --off

Or have the laptop screen off and VGA screen on:
xrandr --output LVDS-0 --off --output VGA-0 --mode 1280x720

Once you happy with it you can make it permanent by adding it ~/.xinitrc

My apologies for waffling on, hope it may help

@seba-carp

Hello sebra-carp , sorry but I don`t speak spanish, but looking at your post @ZING referred you here.

Have you tried ?
xrandr -s 1280x720

@usman_tahir880

As @Zing has mentioned you will need to kill emulation station first, here is another thread which might help:

@strodown said in 6.1 x86_64 will not boot into GUI after update from 6.0:

@elnino @Enigmatic_One

• on PC it is necessary to make a fresh installation!
• several boot issues were raised, to ensure a total boot
  you have to login in ssh to your Recalbox:
  https://recalbox.gitbook.io/tutorials/filesystem/root-access-on-terminal
  then once connect type these commands:
  mount -o remount, rw /
  and
  mv /etc/init.d/S03splash /etc/init.d/splash
  after that
  reboot
  and everything should work at best

@strodown thanks for the tips, I had the same issue with a fresh install of 6.1 on a i5-8400T with iGPU.
