Hi again.

Xrandr responds ‘ Cant open displays’

@jackalpret read this:

@zing nothing works.
All commands with xrandr responds cant load display.
Xorg or x -configure create xorg.conf.new and i copied to /etc/X11 (without .new). But it continuous as same. Cant open displays... i rebooted also.

Did you stop Emulationstation before trying the commands?
Have you tried: "DISPLAY =: 0.0 xrandr"?
What is the result of the "Xorg: 1 -configure" command?
Have you tried editing the xorg file manually?

I need to make it clear that I am not an expert on this, I am trying to help within what I researched about it.

Here are the results:

recalbox pc v4.8 and v6.0 are the same, only different in Xorg -configure
Xorg -configure doesnt work in v4.8:

Xorg -configure creates .new in v6.0:

All the other commands in both versions that I have are the same:

Any idea ?
I'm very sad

@jackalpret Well, I don't understand enough to identify where the error is, so I need to check from the beginning:
at the link:
https://github.com/recalbox/recalbox-os/wiki/Change-display-resolution-on-x86---x86_64
The initial statement says:

Xrandr can be used to set the size, orientation or reflection of the outputs for a screen. A common use scenario would be to use a specific resolution less than the displays maximum resolution. For example a 1080p resolution on a 4K display, or a 720p resolution on a 1080p display.

• ssh into your recalbox: root terminal access

Once connected perform the following:

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

This will copy ~/.xinitrc to /recalbox/share/system (/recalbox/share/system/.xinitrc). This will be the file that we will edit.
From here you can edit the file with vi/nano from ssh with your existing connection, or use winscp/filezilla to edit /recalbox/share/system/.xinitrc
add this to /recalbox/share/system/.xinitrc (1080p as an example)

xrandr -s 1920x1080

Did you do this initial procedure?
Have you tried adding your configuration manually to the .xinitrc file?

Sorry not to be more precise, I am not a developer, I'm just trying to help.

@zing Hi! thanks for all your answers.

I don't know what is happening.

xrandr -s 1920x1080 for example doesnt work :
Can't open display

I know that batocera is another thing, but in batocera, in menu I can choose my display (for example auto, vga, etc), and If i select vga it works fine .... but i like more recalbox over batocera.

[Zing]

@jackalpret Sorry, but it was not clear if you answered what I asked:

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

Did you do this initial procedure?
Have you tried adding your configuration manually to the .xinitrc file?

It's really no use comparing Batocera with Recalbox, they are different systems, and different teams.
What you can do is contact the developers and request these features ...

@jackalpret hi to do this you can follow this tutorial: Change display resolution on x86 x86_64
I am currently testing to fix this problem and make it automatic if you want to give you the trouble to test the automated method do not hesitate to let me know about the discord thank you.

I was able to do it! My steps:

1. ssh on my recalbox
2. cp /etc/X11/xinit/xinitrc ~/.xinitrc
3. add this to /recalbox/share/system/.xinitrc
   xrandr -s 1920x1080
4. uncomment the following line and put my laptop screen :
   xrandr --output eDP1 --off
5. reboot!
